White Raven Strike p. 94
Your eye for tactics allows you to notice an enemy's weak points and attack them with a mighty blow.
The White Raven discipline focuses on tactics, teamwork, and the ability to make an attack that improves your allies' abilities. This strike ruins a foe's defenses.
As part of this maneuver, you make a single melee attack. If it hits, you deal an extra 4d6 points of damage, and the target is considered flat-footed until the start of his next turn.
