Lycanthropic Curse (3.5e Maneuver)

''The curse fell on the opponent who suddenly growled, hair growing on his arms and chest and muscles straining. You make your way out quickly as the feral foe tore into his nearby allies.''

You curse your opponent with a temporary but vicious form of lycanthropy. You may either make this as part of a melee attack, or as a touch attack. An affected subject gains a +4 racial bonus to Strength, but goes insane and simply attacks the nearest creature to the best of its ability, losing sight of friend and foe. They may still cast spells but take no other actions but attacking, even if wounded. They will automatically try to attack the last creature who assaulted them last round before returning to simply fighting the closest target. When the curse ends they regain their sanity and lose the bonus to strength.

Curiously, this curse can be used to undo the effects of confusion and involentary lycanthrophe transformations, helping the target regain sanity. On a touch the target gains another saving throw attempt or control shape check to resist the effects of confusion, insanity, and lycanthropy.

This is a supernatural maneuver.
