Devilish Catharsis (3.5e Maneuver)

Your power positively oozes from you as you stare down your opponent, striking fear into his heart.

You may make an Intimidate check against a DC equal to 10 + the target's Challenge Rating + their Wisdom modifier + any bonuses they have against fear effects). If you succeed, the designated opponent (who must be able to see you and be threatened by you in melee) is considered shaken until the end of their next turn. If you win by 5 or more, the opponent is frightened for the same duration, and if you win by 10 or more they are treated as panicked.
