A thought eater is an ethereal stalker that feeds on the minds of other creatures. It especially savors the minds of psychic creatures and will target them above nonpsychic creatures.
It has transparent, ethereal flesh that makes it look skeletal. Its head is chicken like, but its body is more similar to a predatory mammal.
Ethereal Striker. A thought eater waits on the Ethereal Plane until it finds prey. It will swiftly enter the Material Plane to attack its target’s mind. If it feels it has the advantage, it will use its powers to subdue threats to continue feasting on the mind of its prey. If pressed, it will retreat to the Ethereal Plane and rely on hit and run attacks until it is sated or driven away.
