Ad Misericordiam (3.5e Maneuver)

"You shouldn't kill me, because I'm bleeding so badly already"

When you have fewer hit points than twice your initiator level, any creature that attempts to attack you or otherwise take an action that might cause you harm must succeed on a Will save or become unable to do so for 1 round.

Unlike other Eloquent Speech maneuvers, a creature that succeeds on its Will save is susceptible to Ad Misericordiam again one round later, not 24 hours later.
