Briefly grants additional attack effect together with Evasion if not targeted. (Range depends on weapon.) Certain moves enhance the additional attack, but the effect is reset if you take damage while targeted. Can't be used repeatedly.
Dagger
[Using it with a Ninjutsu Scroll will give you the same effects.] Enhance additional attack by using Evasion, Assassin Stab or Backstep (only if successful). When the enhancement value is 10 or more, it will be consumed to super enhance additional attack if damage is received while Evasion happens.
