Imperator’s Warning (3.5e Maneuver)

''Your presence on the battlefield is a dire warning to your foes. As you down one, you whirl about to strike another.''

As part of this maneuver, you make a single melee attack against an opponent. In order to initiate this maneuver, you must have downed a foe this round (typically by dropping it to below 0 hit points or killing it). If you down a foe while this maneuver is expended, then you may take an immediate action to recover it, but you cannot initiate it that round.
