Ethereal slayers are carnivorous predators that lie in ambush on the Ethereal Plane, waiting for unwitting creatures to enter. They typically wait in spots that have significant cross-planar traffic, such as beside Material Plane buildings that are rich in magical auras. If several attempts have already been made to access a particular Material Plane location via ethereal travel, there is a good chance that a slayer has taken notice and gravitated to that spot.
A spiny, chitinous shell armors an ethereal slayer’s body, and four mandibles surround its drooling mouth. It has two thick, birdlike legs and two arms that end in wicked, four-foot claws, like those of a praying mantis.
Ethereal slayers are ambush predators. They use their detect magic ability to locate strong magical auras, then wait near them for creatures to travel past on the Ethereal Plane. When a creature appears nearby, the slayer uses its dimensional anchor ability to fix its prey on the Ethereal Plane, then attacks with its claws. Should its opponent manage to flee to the Material Plane, the slayer uses its plane shift ability to pursue.
Detect Magic (Su): An ethereal slayer can produce a detect magic effect (caster level 9th) at will.
Dimensional Anchor (Su): An ethereal slayer can produce a dimensional anchor effect (caster level 9th) at will.
Plane Shift (Su): Twice per day, an ethereal slayer can produce a plane shift effect (caster level 9th; self only; save DC 14).
