Invisibility

Magically turns invisible until it attacks or uses Storm Wave or until its concentration ends (as if concentrating on a spell). Any equipment the peri wears or carries is invisible with it.

Storm Wave (1/Day)

Throws its arms forward releasing a blast of stormy wind in a 30' line that is 5 ft. wide. All in line make a DC 12 Dex save. On a failure a creature takes 7 (2d6) lightning and 7 (2d6) thunder and is pushed up to 10 ft. away from the peri. On a success a creature takes half the damage and isn't pushed.
