You may channel your ki power into melee attacks.
Prerequisite: Ki power, sudden strike ability +2d6.
Benefit: You can spend one daily use of ki power to grant yourself a bonus on your next melee attack roll equal to your Wisdom bonus. You also deal extra damage equal to your ninja level plus your current pool of ki power uses (not counting the ki use spent to activate this feat).
