Violent display
You never miss an opportunity to cow foes.
Prerequisite: Dazzling Display, Weapon Focus, base attack bonus +6.
Benefit: When you land a successful sneak attack or confirm a critical hit against a creature with a weapon with which you have Weapon Focus, you can use Dazzling Display as an immediate action.
Special: This feat is available to weretigers, weretiger-kin and those who associate with these creatures.
The reason i'm asking is because of Twisting Fear
Whenever the vigilante causes an opponent to gain the shaken, frightened, or panicked condition, that opponent takes an amount of nonlethal damage equal to the vigilante's reduced hidden strike damage, as the stress wears upon its body. A creature can't take damage from twisting fear more than once per round. Panicked creatures that take damage from twisting fear are too winded even to scream as they flee in terror. Only a stalker vigilante can select this talent.
if it dose not stack i think most weretiger vigilantes will dip one level of rogue or any other class that gains SA at level 1.
each time you make a SA you can try to intimidate all with in 30 feat and deal dmg against them. All day every day a good combo i think. the feat was written before the class was released and SA and HS are very similar to each other.
