Entity: Mountainkeeper Tengu

Source Advanced Player's Guide pg. 25 ^2.0

You come from a line of tengu ascetics, leaving you with a link to the spirits of the world and the Great Beyond. You can cast the disrupt undead cantrip as a primal innate spell at will. A cantrip is heightened to a spell level equal to half your level rounded up. Each time you cast a spell from a tengu heritage or ancestry feat, you can decide whether it’s a divine or primal spell.
