Quintessivore

CREATURE 10

Quintessivores are cunning creatures that wield arcane magic and scalpel-sharp spider limbs that can rend one's soul just as easily as flesh. A quintessivore doesn't immediately kill its prey-it drags the creature to its lair and separates the victim's soul from their body with its bladed limbs. The flicking blades then pull out the creature's individuality, reducing the soul down to pure soul-stuff called quintessence, which the quintessivore then consumes.

Feed on Quintessence (arcane, exploration, manipulate)

Over the course of 1 hour, the quintessivore removes and deconstructs the soul of a creature. The creature must either be captive or have been dead for no more than 2 hours before the start of the process. At the end of the hour, the quintessivore consumes the quintessence of the creature's soul.

For the next month, it gains a +1 status bonus to its spell DC and spell attack roll, and it adds 6th-rank Never Mind and Vampiric Exsanguination to its arcane prepared spells.

Deconstructing a soul maps the unique properties of the creature's soul into the quintessivore's blade-legs. The soul can be reconstructed by binding it to quintessence. A dead quintessivore's soul flees its body as pure quintessence suitable for this purpose.

Suspend Soul (arcane)

The quintessivore suspends the life processes of a dying creature within 15 feet of it. The creature can't decrease or increase its HP or dying value for 10 minutes. The creature can attempt a DC 29 Will save to avoid this effect. If the creature receives magical healing, it can attempt a new save, ending the effect and being healed normally on a success.

The effect ends if the quintessivore uses Suspend Soul again.

Tattered Soul

A creature hit by the quintessivore's blade-leg Strike must succeed at a DC 29 Fortitude save or become Drained 1 (Drained 2 on a critical failure). If the creature is already drained, it's immune to this effect.
