Your beast shape form strikes fear into your opponents.
Prerequisites: Con 19, beast shape class feature.
BENEFIT
When you use beast shape, it is supernaturally ferocious and disquieting in appearance, such that when you attack a creature, you can use this ferocity to frighten observers. Opponents within 30 feet of you when you attack must succeed at a Will save (DC = 10 + half your character level + your Charisma modifier) to resist being affected by your frightful shape. On a failed save, creatures with fewer Hit Dice than you become shaken, or panicked if they have 4 Hit Dice or fewer; in either case, the effect lasts for a number of rounds equal to your character level. An opponent that succeeds at its saving throw is immune to your frightful shape for 24 hours. This is a mind-affecting fear effect.
