Akashti

Soul Shred — Creatures killed by an akashti are difficult to bring back to life or animate as undead. The akashti automatically attempts to counteract any attempt to resurrect or animate as undead any creature that it has killed (counteract modifier +19, counteract rank 5). If the akashti who slew the creature is slain, the creature can be brought back from death or become undead normally.

Manifest Body (concentrate, occult) — Frequency once per day Effect The akashti manifests a hollow humanoid body around their slender skeletal frame over the course of 10 minutes of concentration. If this time is spent within 10 feet of a humanoid body that has been dead for less than a week, the akashti's manifested body looks almost identical to that of the dead humanoid when they lived and functions as a disguise of that creature. If the akashti can consume a portion of the body they're duplicating, they gain a +4 circumstance bonus to Deception checks to Impersonate the creature. While wearing a manifested body, the akashti loses their claw Strike, and their voice sounds like that of the dead creature; they don't possess any of the dead creature's memories or skills and must rely on deception to continue the charade in the face of scrutiny. An akashti's manifested body decays swiftly if they don't take 10 minutes once per day to maintain the manifestation of the false flesh. The body has 10 Hit Points and the same defenses as the akashti. When the body is destroyed, the akashti emerges unharmed, and the fleshy shell left behind scatters into a cloud of red butterflies that swiftly fade into red mist.

Stunning Despair (auditory, incapacitation, mental, occult) — The akashti unleashes overwhelming sobs of despair. Creatures within 30 feet must attempt a DC 29 Will save or become Stunned 1 (Stunned 3 on a critical failure). The akashti can't use Stunning Despair again for 1d4 rounds.
