Phase Beasts

Phase beasts possesses the magical ability to phase in and out of the Ethereal Plane. They seem to appear out of nowhere and quickly vanish after attacking. Their movement on the Ethereal Plane before coming back to the Material Plane makes it seem like they can teleport.

Curiously, many phase beasts appear to be the same variety of beasts that appear have giant versions of themselves in the wild.
