Ioseff Xarwin is site bound to his laboratory.

Site Bound

If a character forcefully presents Fulvia&#x27;s ring to Ioseff as an action with the manipulate trait, he must attempt a DC 26 Will save; he&#x27;s thereafter immune to Recoil for 24 hours.
<hr/>
Critical Success Ioseff is unaffected.
Success Ioseff takes 4d6 mental damage and is <a href="/condition/frightened">Frightened 1</a>.
Failure Ioseff takes 8d6 mental damage and is <a href="/condition/frightened">Frightened 2</a>.
Critical Failure Ioseff takes 8d6 mental damage, is frightened 2, and is <a href="/condition/stunned">Stunned 3</a>.

Recoil

When a ghost is destroyed, it re-forms after [[/br 2d4 #days]]{2d4 days} within the location it&#x27;s bound to, fully healed. A ghost can be permanently destroyed only if someone determines the reason for its existence and sets right whatever prevents the spirit from resting.
<hr/>
In order to put Ioseff to rest, the following three conditions must be met after defeating Ioseff but before he rejuvenates:
<ul>
<li>The undead brain collector in area D6 has been destroyed.</li>
<li>The brains of his wife and children have been freed from the brain collector statue, allowing their souls to move to the Boneyard.</li>
<li>The Void Mirror has been replaced in its frame in the Cosmic Crypt.</li>
</ul>

Rejuvenation

Ioseff takes a -1 item penalty to attack rolls and saving throws against a character who carries Fulvia&#x27;s ring. This penalty doubles to -2 against a character who wears Fulvia&#x27;s ring. At the start of ttheir turn, a character who possesses Fulvia&#x27;s ring can attempt a secret DC 20 Perception check; on a success, they sense a faint compulsion fueled by outrage to present Fulvia&#x27;s ring to the ghost.

Internal Insurrection (disease); Level 7.

Incite Insurrection

Ioseff Xarwin attempts to possess an adjacent corporeal creature. This has the same effect as the <a href="/spell/possession">Possession</a> spell, except since Ioseff Xarwin doesn&#x27;t have a physical body, it is unaffected by that restriction of the spell.
The target must attempt a DC 28 Will save.
<hr/>
Critical Success The target is unaffected.
Success You possess the target but can&#x27;t control it. You ride along in the body while the spell lasts.
Failure You possess the target and take partial control of it. You no longer have a separate turn; instead, you might control the target. At the start of each of the target&#x27;s turns, it attempts another Will save. If it fails, it&#x27;s <a href="/condition/controlled">Controlled</a> by you on that turn; if it succeeds, it chooses its own actions; and if it critically succeeds, it forces you out and the spell ends.
Critical Failure You possess the target fully, and it can only watch as you manipulate it like a puppet. The target is Controlled by you.
A character who carries Fulvia&#x27;s ring on their person gains a +4 item bonus to their save and treats the result of the save as one degree of success better than their rolled result. If Ioseff attempts to use this ability on a character who wears Fulvia&#x27;s ring, he can attempt a Perception check against the ring-wearer&#x27;s Stealth DC to notice the ring in time to avoid the attempt; on a success, he loses the two actions he took to make the attempt but avoids further effects. If he doesn&#x27;t notice the ring and attempts to possess the ring-wearer, the ring-wearer automatically gains a critical success on their Will save, Ioseff is <a href="/condition/stunned">Stunned 3</a>, and he can&#x27;t use Malevolent Possession again for 24 hours.

Malevolent Possession

<hr/>
Effect Ioseff holds up the stump of his left arm, and the streaming blood begins to form a ghostly hand that he then uses to point out a humanoid creature within 30 feet. That creature must attempt a DC 28 Fortitude save.
<hr/>
Critical Success The creature is <a href="/condition/sickened">Sickened 1</a> by a sudden, agonizing pain in their left hand.
Success As critical success, but the creature also takes 2d6 slashing damage and is <a href="/condition/clumsy">Clumsy 1</a> for 1 round as they feel as if their left hand just got lopped off by a hatchet.
Failure The creature is <a href="/condition/sickened">Sickened 2</a>, takes 5d6 slashing damage, and is <a href="/condition/clumsy">Clumsy 2</a> for 1 minute as they feel as if their left hand just got lopped off by a hatchet.
Critical Failure The PC is <a href="/condition/sickened">Sickened 3</a> and takes 8d6 slashing damage and 2d6 bleed damage as their left hand appears to detach and fall to the floor before instantly decaying into bones. The PC is clumsy 2 and <a href="/condition/wounded">Wounded 1</a>. As soon as this wounded condition is removed, the PC&#x27;s hand miraculously returns and the clumsy condition ends.
