You have a connection with a powerful and usually otherworldly entity called an eidolon, and you can use your life force as a conduit to manifest this ephemeral entity into the mortal world. Magic also flows through this conduit from your eidolon into you, so your eidolon determines the type of spells you cast and the spell list you choose from.

Choose a type of eidolon. When you choose your eidolon, you also determine its appearance and general form, within the parameters for that particular type of eidolon. Once you establish your eidolon's type and general appearance, these features can't be changed later, except by selecting special evolution feats that can cause your eidolon to develop new features.

Your magical connection with your eidolon takes the form of a sigil on each of your bodies. As long as your eidolon is manifested, the sigil glows with light and can't be covered or disguised via any means; it will shine through clothing, appear over cloaks, and remain unaffected by obfuscating magic. This, combined with the way that the two of you clearly act in tandem, makes it readily apparent to an intelligent observer that the two of you are connected in some way, even if the person has never encountered a summoner before.

You bring your eidolon into reality with the Manifest Eidolon action.

Your eidolon is no mere minion. It doesn't have the minion or summoned trait, and the two of you work together and coordinate your actions. You and your eidolon share your actions and multiple attack penalty. Each round, you can use any of your actions (including reactions and free actions) for yourself or your eidolon.

You coordinate your actions with your eidolon more efficiently when you Act Together. Your connection with your eidolon allows you to communicate with it telepathically at all times, even when it isn't manifested. You also gain the Share Senses action.

Lastly, the connection between you and your eidolon means you both share a single pool of Hit Points. Damage taken by either you or the eidolon reduces your Hit Points, while healing either of you recovers your Hit Points. Like with your actions, if you and your eidolon are both subject to the same effect that affects your Hit Points, you apply those effects only once (applying the greater effect, if applicable). For instance, if you and your eidolon get caught in an area effect that would heal or damage you both, only the greater amount of healing or damage applies.

Gear and your Eidolon

Your eidolon can't wear or use magic items, except for items with the eidolon trait. An eidolon can have up to two items invested. Your eidolon's link to you means it can benefit from certain magic items invested by you.

• Your eidolon gains item bonuses to Perception and skills from any magical items that you have invested.
• Your eidolon increases its item bonus to AC based on your armor's armor potency rune or bracers of armor. It also gains an item bonus to its saves from the resilient rune on your armor or from your bracers of armor. Other permanent items that grant or increase item bonuses to AC and saves might convey a similar benefit, as determined by the GM.
• Your eidolon's Strikes benefit from the fundamental and property runes on your handwraps of mighty blows. Alternatively, you can Invest a magic weapon (even though magic weapons can't normally be Invested) to share its fundamental and property runes with your eidolon. You share these benefits only while you're holding the weapon, and you can have no more than one weapon invested in this way at a time. In either case, the eidolon gains only the benefits that can apply to its attacks, with the same limitations noted in handwraps of mighty blows.

Lost and Altered Actions

If you or your eidolon becomes slowed, stunned, quickened, or otherwise affected by something that changes the actions you gain at the start of each turn, it affects your shared actions. However, if you are both subject to such an effect, apply only the more severe one. For instance, if you or your eidolon were Slowed 1, you would start your turn with one fewer action, but if you were both slowed 1, you would still lose only one action, rather than adding the two slowed effects together. However, if you were slowed 1 and your eidolon Slowed 2, you'd have two fewer actions, because that's the more severe effect. If only one of you becomes restricted in how you can spend your actions, that restriction doesn't automatically extend to the other; for example, if your eidolon became Immobilized or petrified, it wouldn't be able to move, but you could still use your actions to move. The GM resolves any situation that's unclear.

You, as the player, control both your summoner and your eidolon, and the two are generally considered to cooperate unless you decide for them not to. While a summoner's link with an eidolon is a partnership, ultimately the eidolon is linked to you, not the other way around. If there's ever a conflict of who should act, you win out over your eidolon. This means that if the eidolon comes under an effect that would take its actions out of your control, such as the Confused or controlled condition, you can use all of your shared actions so your eidolon doesn't have any actions remaining to cause trouble (as long as you are able to act). However, if you came under such an effect, you would simply use all of your shared actions, preventing your eidolon from acting.

Your link to your eidolon grants you limited magic connected to your eidolon's nature. You can cast spells using the Cast a Spell activity, and you can supply material, somatic, and verbal components when casting spells. Because of the magic you draw from your eidolon, you can usually replace material components with somatic components, so you don't need a material component pouch.

Each day, you can cast one 1st-rank spell and five cantrips. You must know spells to cast them, and you learn them via the spell repertoire class feature. The number of spells you can cast each day is called your spell slots.

As you increase in level as a summoner, the magical link with your eidolon grants you additional, more powerful spell slots. Your total number of spell slots and the highest rank of spells you can cast are shown in Table 2-4: Summoner Spells per Day. Because of the way you draw magic from your connection to your eidolon, you begin to lose lower-rank spell slots once you reach 5th level. The maximum number of spell slots you get from the summoner class is four, starting when you reach 4th level. For anything that requires the ability to cast spells of a certain level that's lower than the highest slots you have, you still qualify even if you no longer have spell slots at those levels.

Some of your spells require you to attempt a spell attack roll to see how effective they are, or have your enemies roll against your spell DC (typically by attempting a saving throw). Since your key ability is Charisma, your spell attack rolls and spell DCs use your Charisma modifier. Details on calculating these statistics appear on page 447 of the Core Rulebook.

Heightening Spells

When you gain spell slots of 2nd level and higher, you can fill those slots with stronger versions of lower-rank spells. This increases the spell's rank, heightening it to match the spell slot. Many spells have specific improvements when they are heightened to certain ranks.

Cantrips

A cantrip is a special type of spell that doesn't use spell slots. You can cast a cantrip at will, any number of times per day. A cantrip is always automatically heightened to half your level rounded up-this is usually equal to the highest rank of spell you can cast as a summoner. For example, as a 1st-level summoner, your cantrips are 1st-rank spells, and as a 5th-level summoner, your cantrips are 3rd-rank spells.

Your connection to your eidolon allows you to cast link spells, special spells that have been forged through your shared connection with your eidolon. Link spells are a type of focus spell. It costs 1 Focus Point to cast a focus spell, and you start with a focus pool of 1 Focus Point. You refill your focus pool during your daily preparations, and you can regain 1 Focus Point by spending 10 minutes using the Refocus activity to specifically connect with your eidolon, such as by having a heart-to-heart conversation, playing together, or meditating in unison on the nature of your bond.

Focus spells are automatically heightened to half your level rounded up, much like cantrips. Focus spells don't require spell slots, and you can't cast them using spell slots. Taking feats can give you more focus spells and increase the size of your focus pool, though your focus pool can never hold more than 3 Focus Points. The full rules for focus spells appear on page 300 of the Core Rulebook.

You learn the Evolution Surge link spell, which allows you to grant your eidolon one of several useful benefits.

Link Cantrips

Link cantrips are special link spells that don't cost Focus Points, so you can cast them as often as you like. Link cantrips are in addition to the cantrips you choose from your tradition's spell list. Generally, only feats can give you more link cantrips. Unlike other cantrips, you can't swap out link cantrips gained from summoner feats at a later level, unless you swap out the specific feat via retraining.

You learn the Boost Eidolon link cantrip, which briefly improves your eidolon's capabilities, allowing it to attack with greater power.

Evolution feats are a special type of summoner class feat that allow you to customize your eidolon through your shared link. You gain an evolution feat for your eidolon at 1st level, representing the differences that make it unique from other eidolons of its type. If you retrain this feat, the feat you replace it with must also be an evolution feat.

You and your eidolon work together to remain alert to threats around you, allowing you to perceive far more together than you could individually. Your proficiency rank in Perception and your eidolon's proficiency rank in Perception increase to expert.

All of your spells are signature spells. That means that if you know a spell, you can heighten it freely by casting it from a higher-rank spell slot, up to the maximum rank of spell you can cast. You can similarly cast any of its lower-rank versions without learning them separately.

Your eidolon becomes more capable of using its unarmed attacks. Its proficiency rank for unarmed attacks increases to expert.

Your connection with your eidolon strengthens, granting your eidolon access to a new ability depending on its type, as described in Eidolon Abilities in each eidolon's entry.

Your eidolon has learned how to inflict greater injuries with its unarmed attacks. It deals 2 additional damage with unarmed attacks in which it's an expert. This damage increases to 3 if it's a master, and 4 if it's legendary.

You and your eidolon boost each other's reflexes, allowing you both to roll away from danger. Your proficiency rank for Reflex saves and your eidolon's proficiency rank for Reflex saves increase to expert.

Your eidolon increases its ability to avoid attacks. Its proficiency rank for unarmored defense increases to expert.

You and your eidolon boost each other's reflexes, allowing you both to roll away from danger. Your proficiency rank for Reflex saves and your eidolon's proficiency rank for Reflex saves increase to expert.

The flow of magic and your defensive training combine to help you get out of the way before an attack. Your proficiency rank in unarmored defense increases to expert.

Your eidolon truly masters its unarmed attacks, reaching greater heights. Its proficiency rank for unarmed attacks increases to master.

You've learned how to inflict greater injuries with the weapons you know best. You deal an additional 2 damage with weapons and unarmed attacks in which you are an expert. This damage increases to 3 if you're a master, and 4 if you're legendary.

Your eidolon's damage from weapon specialization increases to 4 with unarmed attacks in which it's an expert, 6 if it's a master, and 8 if it's legendary.

You and your eidolon steel your mind together against effects that threaten you, each protecting the others' minds from danger. Your and your eidolon's proficiency ranks for Will saves increase to master. When you roll a success on a Will save, you get a critical success instead. When your eidolon rolls a success on a Will save, it gets a critical success instead.

Your connection with your eidolon approaches its peak, granting your eidolon access to a powerful new ability depending on its type, as described in Eidolon Abilities in each eidolon's entry. This ability also increases one of the eidolon's ability scores by 2.

Your eidolon's form becomes particularly difficult to assail. Its proficiency rank for unarmored defense increases to master.

You can manifest your eidolon with incredible speed. You can use Manifest Eidolon as a single action, instead of a three-action activity.

Your eidolon is a celestial messenger, a member of the angelic host with a unique link to you, allowing them to carry a special message to the mortal world at your side. Most angel eidolons are roughly humanoid in form, with feathered wings, glowing eyes, halos, or similar angelic features. However, some take the form of smaller angelic servitors like the winged helmet cassisian angel instead. The two of you are destined for an important role in the plans of the celestial realms. Though a true angel, your angel eidolon's link to you as a mortal prevents them from casting the angelic messenger ritual, even if they somehow learn it.

Hallowed Strikes

Your eidolon's attacks are hallowed by the celestial realms. Your eidolon's unarmed Strikes deal an extra 1 good damage; as usual, this extra damage harms only evil creatures or those with a weakness to good damage. Additionally, your eidolon can make nonlethal attacks with its unarmed attacks without taking the usual –2 circumstance penalty.

Traveler's Aura7th

Your eidolon emanates a powerful aura—resembling that of an astral deva—that protects creatures as they travel. The aura has the abjuration, aura, and divine traits. Your eidolon and its allies within a 20-foot emanation are protected from severe heat and cold, and your eidolon is never Off Guard to creatures inside the aura that are of a lower level than the eidolon. When you gain the transcendence class feature, this evolves to the full benefits of an astral deva; your eidolon and allies in the aura are protected from environmental damage from any plane, including severe and extreme heat and cold as well as more unusual dangers.

Angelic Mercy17th

Your eidolon's angelic power allows them to assuage a variety of ailments, just like most other powerful angels. Your eidolon can cast remove curse, remove disease, remove fear, and remove paralysis once per day each as 9th-level divine innate spells.

Your eidolon is a lost soul, bound to the mortal world by undying anger or a bitter grudge. Most phantom eidolons are humanoids with a spectral or ectoplasmic appearance, though some take far stranger forms. Your link with your eidolon prevents it from succumbing to corruption and undeath. Together, you will need to decide whether to work with your eidolon to control its anger, or channel its wrath into power.

Anger Aura17th

Your eidolon exudes wrath in an aura around it, rousing the ire of nearby creatures and causing their defenses to crack as they seethe with rage. Your eidolon gains a 20-foot anger aura, which has the aura, emotion, enchantment, mental, and occult traits. The resistances of any creature in the aura, including you, your allies, your enemies, and your eidolon, are reduced by an amount equal to 3 + your eidolon's Constitution modifier. Your eidolon can hold in its rage by spending a single action, which has the concentrate trait. This reduces the aura's effect to affect only your eidolon. It can take this action again to reinstate the full effect of its aura. Creatures in a barbarian Rage, Seething Frenzy, or similar ability that allows them to channel their anger aren't affected by the anger aura.

Your eidolon is a manifestation of the life force of nature in the form of a powerful magical beast that often has animal features, possibly even several from different species. You might have learned the way to connect with the world's life force via a specific philosophy or practice, such as the beliefs of the god callers of Sarkoris, or formed a bond on your own. Regardless, your link to your eidolon allows you both to grow in power and influence to keep your home safe from those who would despoil it.

Your eidolon is a mental construct based on an astral thoughtform and given physical presence and life by its connection to you, its shape limited only by your imagination. Your eidolon's appearance and physical form vary based on your shared vision for its construction, from clockworks to stuffed dolls and everything between, and it's not uncommon for that appearance to change greatly as your construct gains evolutions. Because it arises from an astral entity, your construct is no mindless servitor, but a fully thinking being with its own ideas, goals, and even emotions. These entities are extremely diverse; while many construct eidolons come from a powerful symbiotic connection with astral denizens, just as many arise from the forgotten memories of ancient empires and craftworks drifting across the Silver Sea of the Astral Plane.

Construct Heart

Your construct eidolon has a link directly to your life force, which renders it a living creature and therefore susceptible to many ailments that bother only the living, though it does possess some resistances to these effects. It doesn't have a construct's normal immunities, but does gain a +2 circumstance bonus to saving throws against death effects, disease, necromancy, and poison effects, as well as effects causing the Fatigued or Sickened conditions. Additionally, its astral essence bleeds off slowly, and it only needs to succeed at a DC 10 Flat to remove persistent bleed damage (or DC 5 after receiving particularly effective aid).

Reconfigured Evolution7th

Your construct eidolon is particularly easy to reconfigure, gaining an additional evolution that suits both of your whims. Choose one additional evolution feat of 6th level or lower. Your eidolon gains that feat. You can Retrain this feat for any other evolution feat of 6th level or lower with only a single day of downtime if you succeed at a Crafting check, with a standard DC of your eidolon's level. If you fail, you can try again on a later day. Many summoners choose Eidolon's Wrath for this ability.

Ultimate Reconfiguration17th

Your construct eidolon becomes even more customizable. Choose an evolution feat of 16th level or lower. Your eidolon gains that feat. You can spend downtime to adjust it using Crafting, just like the feat from reconfigured evolution. Many summoners select Ever-Vigilant Senses for this ability.

Your eidolon is a demon, born of mortal sin congealed amid the chaos and evil of the Abyss, using its link to you to spread chaos at your side. Choose an associated sin for your demon. Demon eidolons have appearances as varied as the infinite Abyss. While demons are inherently untrustworthy, your demon eidolon has reached an accord with you and generally keeps it, though that doesn't mean your eidolon isn't actively working to bring your life deeper into its associated sin. Though a true demon, your demon eidolon's link to you as a mortal prevents them from casting the abyssal pact ritual, even if they somehow learn it.

Demonic Strikes

Your eidolon's attacks are corrupted by the Abyss and imbued with pure evil and shifting chaos. All your eidolon's unarmed Strikes deal an extra 1 evil damage; as usual, this extra damage harms only good creatures or those with a weakness to evil damage. Additionally, choose one of your eidolon's unarmed attacks that deals physical damage; it gains the versatile trait for a different type of physical damage you choose.

Visions of Sin7th

Your demon is born of sin and can project the sin it is formed from into the minds of others. It gains the Visions Of Sin activity.

Blasphemous Decree17th

Your demon utters indescribable words writhing with its associated sin. It can cast an evil Divine Decree once per day as a 9th-level spell. You are unaffected by this decree, even if you aren't evil. At 19th level, this becomes a 10th-level divine decree instead.

Your eidolon is a lost soul, unable to escape the mortal world due to a strong sense of duty, an undying devotion, or a need to complete an important task. Most phantom eidolons are humanoid with a spectral or ectoplasmic appearance, though some take far stranger forms.

Steadfast Devotion7th

Your eidolon's dedication makes it extremely challenging for your foes to bend its mind. Your eidolon gains a +2 circumstance bonus to saving throws against mental effects, and if they roll a success against such an effect, they get a critical success instead. If you have the shared resolve class feature and your eidolon rolls a critical failure against a mental effect, they get a failure instead.

Devotion Aura17th

After fighting at your side for so long, your eidolon has become as devoted to protecting you and your allies as it is to its original cause. It gains a 20-foot devotion aura, which has the abjuration, aura, and occult traits. Whenever one of your eidolon's allies within the aura takes damage, you can reduce the damage by your eidolon's Constitution modifier. You lose a number of Hit Points equal to half the amount by which the eidolon reduced the damage, rounded down. If the damage was lower than the Constitution modifier, base the damage you take on the actual amount of damage prevented.

Because dragons have a strong connection to magic, their minds can often leave an echo floating in the Astral Plane. Such an entity is extremely powerful but unable to interact with the outside world on its own. Dragon eidolons manifest in the powerful, scaled forms they had in life; most take the form of true dragons (albeit smaller), but some manifest as drakes or other draconic beings. You have forged a connection with such a dragon eidolon and together, you seek to grow as powerful as an ancient wyrm.

Your eidolon is a primal chunk of elemental matter infused with sapience, power, and identity, but unable to manifest a true form of their own without the life force you provide via your connection. Most elementals in their natural environment already have different sorts of forms, from vaguely humanoid, to animalistic, to simple masses of their component element. As your life force provides your eidolon the instincts necessary to adopt a physical form, their appearance varies based on the strength of their own self image and your prior exposure to elementals.

Elemental eidolons tend to reach their unusual state—powerful but formless—as the result of large scale events or cataclysms, such as the war to seal the benevolent Elemental Lords or their recent unsealing. Whether elemental eidolons possess any memories of a previous life or are a new sapience formed from left-over essence of a mighty servant of the Elemental Lords brought low varies from eidolon to eidolon. Together, you might undertake a journey to understand your eidolon's mysterious past or leave the past behind and forge a new destiny of your own.

Eidolon Abilities Initial elemental core; Symbiosis elemental burst; Transcendence elemental maelstrom

Elemental Core

Your elemental eidolon is an amalgam of elemental matter and mortal life force, which helps protect them from certain effects that are more harmful to mortals than elementals. They gain a +2 circumstance bonus to saving throws against poison and sleep effects, as well as effects causing the Paralyzed condition. Additionally, their elemental essence bleeds less easily than flesh, so the DC of any flat check they make to remove persistent bleed damage is 10 (or 5 after receiving particularly effective aid). Choose for your eidolon to be an air, earth, fire, metal, wood, or water elemental. Your eidolon and all their unarmed attacks gain the trait of the chosen element, and the eidolon gains additional effects based on your choice.

Air: Your eidolon is formed from elemental air and is light as a breeze. Your eidolon can Leap, High Jump, and Long Jump twice as far, and doesn't take falling damage.

Earth: Your eidolon is formed from elemental earth, and is incredibly hard to move by force. Your eidolon gains a +2 circumstance bonus to their Fortitude or Reflex DCs against attempts to Shove or Trip them. This bonus also applies to saving throws against spells or effects that attempt to knock them Prone. In addition, if any effect would force them to move 10 feet or more, they're moved only half the distance.

Fire: Your eidolon is formed from elemental fire and burns with embers of flame. Your eidolon gains resistance equal to half your level (minimum 1) to fire and an equal amount of weakness to cold and water. Their unarmed attacks deal 1 additional fire damage.

Metal: Your eidolon is formed from elemental metal and can adapt their metallic form to battle. One of your eidolon's starting melee unarmed attacks gains the versatile bludgeoning, piercing, or slashing trait, as your eidolon learns how to shift the metal into various weaponlike forms.

Water: Your eidolon is formed from elemental water and swims with ease. Your eidolon gains the amphibious trait, allowing them to breathe in water and air and to avoid the normal –2 penalty for making bludgeoning and slashing unarmed Strikes underwater. Your eidolon's land Speed is reduced to 15 feet, and they gain a swim Speed of 25 feet. You can take the Amphibious Form feat to increase their land Speed back up to 25 feet, as described in the feat.

Wood: Your eidolon is formed from elemental wood, and its living wooden form twists and regrows as you focus your elemental energies. You can choose to have your eidolon gain the plant trait. Whenever you Refocus, your eidolon regains a number of Hit Points equal to double your level.

Elemental Burst7th

Your eidolon can form projectile attacks from their own body. Your eidolon gains the Elemental Burst activity.

Elemental Maelstrom17th

Your eidolon can form a swirling vortex of elemental matter and move across the battlefield, damaging everything in their path. Your eidolon gains the Elemental Maelstrom activity.

Your eidolon is a fey, a capricious being of the mysterious First World. Many fey appear similar to mortal humanoids with unusual features such as pointed ears, wings, or bodies composed of natural elements, but the full variety of fey is endless, and many others appear completely inhuman. Fey from the First World never truly die, instead forming a new creature. Fey eidolons usually come about when a summoner helps stabilize a difficult reformation. This means your fey eidolon likely lived a different life just before meeting you and might remember fragments of its old memories. Together, you might have to unravel a memory from your eidolon's past life among the fey.

Fey Gift Spells

Your eidolon expands your primal magic with enchantment and illusion magic, allowing both of you to wield the power of fey charm and glamour. When you add spells to your repertoire, you can choose from the primal list as well as from enchantment and illusion spells that appear on the arcane spell list. As usual for when you add spells of a different tradition to your spell list, you're still a primal spellcaster, so all of your spells are primal spells.

Your eidolon gains the Magical Understudy summoner feat, despite not meeting the prerequisite level, and it can choose fey gift cantrips in addition to primal cantrips. As usual for a feat you are granted by name, you can't retrain Magical Understudy into another feat.

Fey Mischief7th

Your eidolon's fey magic becomes more powerful and mischievous. Your eidolon gains the Magical Adept feat, despite not meeting the prerequisite level, and can choose from fey gift spells in addition to primal spells.

Fey Chicanery17th

Ever full of tricks, your fey eidolon twists magical protections into your shared life force, granting it a contingency in its back pocket for desperate situations. During your daily preparations, your eidolon can cast a contingency spell. The 4th-rank spell it chooses must come from the primal or fey gift list, and must either be common or be another spell you have access to.

Your eidolon is an intelligent plant, formed from the same disembodied fragments of nature's life energy that become leshys. Plant eidolons tend to be curious and adaptable, with temperaments based on the parts of mortal culture they feel affinity toward. Despite coming from the same source, plant eidolons don't always look like leshys. Plant eidolons have forms that vary greatly and can look like almost any kind of plant creature in existence. Some even resemble plant creatures so strange they are impossible to identify.

Tendril Strike

Your eidolon can stretch out vines and roots, attacking foes outside its reach. It gains the Tendril Strike action.

Growing Vines7th

Your eidolon's vines and branches lengthen even more. All your eidolon's melee unarmed attacks gain the reach trait.

Field of Roots17th

Your eidolon learns how to send its roots underground to hinder foes. It gains the Field Of Roots activity.

Your eidolon is a psychopomp, a creature whose sworn duty is to usher souls safely to the afterlife and maintain the courts of the dead. Psychopomp eidolons have a variety of appearances, but since they often traffic with mortals, their form typically includes an elaborate mask. You and your psychopomp eidolon share an important fate together, whether it relates directly to your own soul or to a mission that will somehow protect the souls of others.

Eidolon AbilitiesInitial spirit touch; Symbiosis hidden watcher; Transcendence spirit taker

Spirit Touch

Your eidolon's attacks possess a psychopomp's ability to harm the living and the dead. Your eidolon's unarmed Strikes affect incorporeal creatures as though etched with a Ghost Touch property rune and deal an extra 1 void damage to living creatures and an extra 1 vitality damage to undead.

Hidden Watcher7th

Your eidolon can render both of you unseen. Once per hour, it can cast Invisibility targeting you, them, or both of you at once. If the spell targeted both of you, the spell ends for both of you if either of you uses a hostile action.

Spirit Taker17th

Your eidolon is particularly capable when it comes to handling bodiless spirits and putting undead to their final rest. Your eidolon can see incorporeal creatures inside of solid objects and can attack them with Strikes without penalty; an incorporeal creature in a solid object that takes damage from your eidolon's Strike is expelled from the object to the nearest available space, moving closer to your eidolon if possible.

Additionally, your eidolon can target or affect a creature projecting its consciousness (such as via Project Image) or possessing another creature, even if its body is elsewhere, though your eidolon must know about the possession or projection and choose to do so.

Finally, the spirit of an undead destroyed by your eidolon's Strikes is sent directly to the Boneyard for judgment; an undead with an ability to avoid such a fate automatically, such as a ghost's rejuvenation, can attempt a counteract check against your spell DC to return via that ability as normal. In that case, it uses its Will save modifier as its counteract modifier.

Your eidolon is a collective of primal energy and nature spirits, gathered into a single fragmentary being. This collection of natural energy has neither form nor identity until bonded with a summoner. You give these spirits purpose, connecting with them and drawing them through to the physical realm. When manifesting, these nature spirits don a simple form, adopting the guise of many Tiny animals. Each of these animals is the same creature and is marked with your summoner's sigil. The act of manifesting in this swarm form temporarily binds the spirits together into one being, making the eidolon a single entity—one mind and personality speaking with a multitude of voices, and a multitude of bodies acting in concert with a singular purpose.

Eidolon Abilities Initial swarm form; Symbiosis sudden shift; Transcendence sickening swarm

Swarm Form

Your eidolon is an intelligent swarm composed of hundreds of Tiny creatures, and it's immune to the Grabbed, Prone, and Restrained conditions. It can fit through tight spaces as though it were a Tiny creature. It has weakness to area damage equal to its level. Your eidolon has two forms: condensed and dispersed. When you Manifest Eidolon, it manifests condensed. It can switch between these two forms as a single action that has the concentrate trait.

Condensed Form: When condensed, your eidolon draws all its component bodies into a single, condensed mound that functions as a Medium creature. It has a reach of 5 feet, can make Strikes, and can't occupy the same space as other creatures. While condensed, it can use the Haunting Visage action.

Dispersed Form: When dispersed, your eidolon scatters its component bodies across a wider area, increasing its size by one category (to Large for most swarm eidolons). It has a reach of 0 feet, can't make Strikes, and can occupy the same space as other creatures. While dispersed, it can use the Swarming Assault activity.

Sudden Shift7th

Once per round, your eidolon can switch forms between condensed and dispersed as a free action, rather than a single action. In addition, your eidolon gains the Redistribute reaction.

Sickening Form17th

Your eidolon is particularly good at distracting and hindering its foes while dispersed. While dispersed, spaces your eidolon occupies are difficult terrain for other creatures. In addition, your eidolon gains the Sickening Assault action.

Your eidolon is an undead spirit pulled from the Ethereal Plane or Negative Energy Plane, embodied, and bound to your life force in an unusual, potentially antithetical way that even other summoners can't quite understand. Undead eidolons take about every imaginable shape and form, as their bodies manifest from their connection to you. Their ultimate form can be influenced by an amalgamation of the echoes and memories of their old life before becoming undead, their cause of death, their encounters in the afterlife, and portions of your own essences. Together, you and your eidolon need to explore the mysteries of life, death, and undeath to understand what your bond means for both of your futures.

Eidolon Abilities Initial negative essence; Symbiosis drain life; Transcendence rejuvenation

Negative Essence

Your undead eidolon has a link directly to your life force, which grants it a twilight state between living and undead. This renders it a living creature and therefore susceptible to many ailments that bother only the living, though it does possess some resistances to these effects. The eidolon has negative healing, meaning it heals from negative energy effects that heal undead and is damaged by positive energy effects that damage undead. It doesn't have an undead's normal immunities, but it does gain a +2 circumstance bonus to saving throws against death effects, disease, and poison effects, and non-damaging effects that target only undead. Additionally, its necrotic essence stanches its wounds easily. The flat check to remove persistent bleed damage from the eidolon is DC 10 (or DC 5 after receiving particularly effective aid).

Drain Life7th

Your eidolon's link with you sustains it, but it still craves the life essence of the living, whether through blood or pure essence. It gains the Drain Life activity.

Rejuvenation17th

Your eidolon's unusual connection with you allows you both to rejuvenate when defeated. The first time each day your turn begins while you're dying, you instantly regain a number of Hit Points equal to three times your level and wake up. (Increase your wounded condition as normal.) You can immediately Manifest Your Eidolon as a free action. You can then take your turn as normal.
