A kaortic hulk eats anything, even undead, constructs, or oozes. Despite its bulk, it attempts to use its spell-like abilities to maneuver itself into places where it couldn't normally reach, then attack its prey while initially invisible and within a sheath of silence.

Reluctant Servant (Ex): If a kaortic hulk is called into service through a spell or other effect, there is a 1% cumulative chance each round that it turns on the creature that summoned it.

Spell-like Abilities: 2/day - gaseous form, spider climb, invisibility, silence. Caster level 8th.

Extraplanar Subtype

A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.

Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
