Cephalophix

CREATURE 5

The striking image of the cephalophix's head resting in their hands is enough to give any mortal pause, but the horrifying shrieks and splattering black tar that spray from their mouths is disturbing to even other devils. Cephalophixes hate all magic with passion and fury, and they especially loathe divine magic, believing it to be the gods' unfair finger on the scales of planar conflict. The irony that they require magic to combat it isn't lost on them, but they aren't above any method that leads to the death of another magic user. Their hatred of all magic makes it difficult for other devils to work with cephalophixes, and more powerful devils usually keep them in soundproof cages until they're needed. Cephalophixes prefer this arrangement as well, meditating in solitude far from the magic and its users that they despise.

Tortured Shriek (sonic)

The cephalophix unleashes a deafening shriek, dealing 2d10 sonic damage to all creatures in a 30-foot cone with a DC 19 basic Fortitude save. Creatures that fail are also Deafened until the start of the cephalophix's next turn, or for 1 minute on a critical failure.
