Leng Ghoul

CREATURE 10

UNCOMMON MEDIUM CHAOTIC DREAM EVIL GHOUL UNDEAD UNHOLY

In the icy nightmare dimension of Leng, ghouls with hoofed feet gather in morbid groups to worship and research, forming societies that mockingly mimic (and in their opinion, surpass) those of the living. Most worship the malevolent gods of the Elder Mythos and see the living as little more than fodder who will eventually die and provide memories for Leng ghouls to consume and absorb. Not all Leng ghouls are evil, but most are, and even those who aren't possess sardonic senses of humor and grisly appetites that make them disturbing allies at best.

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Absorb Memories (manipulate)

Requirements The Leng ghoul is adjacent to the corpse of a creature that retains flesh on its bones

Effect The Leng ghoul devours a chunk of the corpse and regains 6d6 healing Hit Points. At the same time, they also absorb some of the memories stored in the flesh from when the corpse was alive, gaining a +1 status bonus to all skill checks for 10 minutes.

The Leng ghoul can immediately attempt an Occultism check to learn one non-secret memory the corpse had when it was alive (use the standard DC for the creature's level). The exact memory learned is determined by the GM but is typically something of use to the Leng ghoul. The memory can't be one the creature was trying to keep secret unless the check was a critical success.

A Leng ghoul can Absorb Memories from any given corpse only once.

Paralysis (incapacitation, occult)

Any living creature hit by a Leng ghoul's attack must succeed at a DC 28 Fortitude save or become Paralyzed. It can attempt a new save at the end of each of its turns, and the DC cumulatively decreases by 1 on each such save.

Sneak Attack

A Leng ghoul deals an extra 2d6 precision damage to Off-Guard creatures.
