Rapid Wolf Strike p. 88
You foam at the mouth and scream in rage as you make a powerful attack against your enemy. You set aside all thoughts of defense as you lunge forward.
For a split-second, you unleash the barely controlled, primal rage that surges within you. As part of this maneuver, you make a single melee attack. You gain a +4 bonus on this attack roll and deal an extra 2d6 points of damage. You take a -4 penalty to AC until the start of your next turn, as this wild strike sends you off balance and hinders your defenses.
