A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn&#x27;t give any special access to their thoughts, and communicates no more information than normal speech would.

Telepathy 100 feet

The monster can cast its at-will spells any number of times without using up spell slots.

At-Will Spells

A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

Stygian Guardian

Troops are composed of many individuals, represented by four &quot;segments&quot; on a battle grid. Each segment is 10 feet on each side and as tall as the individual members of the troop. Segments must remain contiguous. Each one has to share at least 5 feet of one of its edges with another segment—being adjacent on a diagonal isn&#x27;t sufficient! You can measure flanking, cover, and the like using the center of any segment.
A troop has two Hit Point thresholds in its HP entry and loses segments as it crosses thresholds. Typically, the higher threshold is at 2/3 of the troop&#x27;s maximum Hit Points and the lower is at 1/3 of its maximum. Once the troop drops below the higher threshold, it loses one segment, leaving three segments (12 squares) remaining and setting the first threshold as the troop&#x27;s new maximum Hit Points. This repeats when the troop drops below the lower threshold, leaving two segments (8 squares). At 0 Hit Points, the troop disperses entirely, with the few remaining members surrendering, @UUID[Compendium.pf2e.conditionitems.Item.sDPxOjQ9kx2RZE8D]{Fleeing}, or easily dispatched, as determined by the GM. Typically the creature who caused the troop to lose a segment decides which to remove, or the GM decides when a specific creature wasn&#x27;t responsible. To restore lost segments and maximum Hit Points, a troop needs to spend downtime to use long-term treatment on casualties or recruit new members to replace the fallen.
Troops are typically immune to non-damaging effects that target a single creature, such as a @UUID[Compendium.pf2e.spells-srd.Item.vLA0q0WOK2YPuJs6]{Charm} spell or the @UUID[Compendium.pf2e.actionspf2e.Item.2u915NdUyQan6uKF]{Demoralize} action. An ability that can target 5 or more creatures can target an entire segment, increasing to two segments if it can target 10 or more creatures and to the entire troop if it can target 20 or more creatures. An ability that affects all creatures in a certain range affects all segments in range (make any checks or saves separately for each segment). As examples, an 8th rank charm spell (with 10 targets) can affect two segments, and an ability that Demoralizes all creatures within 30 feet of you would affect all segments that are fully within that range. A non-damaging ability that would prevent a segment from acting, cause them to flee, or otherwise make them unable to function as part of the troop for a round or more removes the segment entirely. The troop loses a number of HP required to bring it to the next threshold. If an ability both deals damage and has a non-damaging effect, apply the damage then the rest of the effect.

Troop Defenses

Whenever a troop moves, you move one of its segments and the other segments follow behind it. At the end of the movement, you can group the other segments adjacent to the one you moved as you see fit, provided none of them moves farther than the moving segment. If you choose not to move the troop any distance, you can instead reshape the position of all the segments as long as one stays in place.

Troop Movement

The infernal tide conjures murky water to fill the lungs of all creatures that can&#x27;t breathe water within a 30-foot cone. Each target in the area must attempt a DC 30 Fortitude save.<hr/>Critical Success The target is unaffected.
Success The target coughs up water and becomes <a href="/condition/sickened">Sickened 1</a>.
Failure The target must hold its breath. The only action it can take is to attempt a DC 30 Fortitude save to expel the water, which is a single action.
Critical Failure The target falls <a href="/condition/unconscious">Unconscious</a> and begins suffocating. If the target succeeds at its Fortitude save while suffocating, it coughs up the water and can breathe again.
