Selkie

This beautiful woman changes shape rapidly to become a sleek, aquatic creature with a gray hide of short fur. Her webbed hands end in sharp claws, and her jaws open unnaturally wide to reveal pointed teeth.

SPECIAL ABILITIES

Echo of Reason (Su)

A selkie can instinctively alter the intonation of its voice to make anything it says sound more pleasing to those who understand it. When using the Bluff skill, a selkie treats its lies as one step more believable for the purposes of bonuses or penalties on the check.

Shake (Ex)

On a successful critical hit with its bite attack, a selkie automatically violently shakes a Large or smaller target. The target must succeed at a DC 15 Fortitude save or it is dazed for 1 round. Even on a successful save, the target still takes a –2 penalty on all attack rolls and skill checks for the next 2 rounds. The save DC is Constitution-based.
