Flurry of Possibilities (3.5e Maneuver)

You fracture probability for a few moments, allowing you to choose which possible strikes you wish to call into existence.

Until the end of turn, whenever you make a melee attack, you make two attack rolls, and use the higher result to determine whether or not the attack hit. If you use a strike that allows you to make multiple attack rolls for one attack, this boost does not grant you any additional rolls on that attack. This maneuver is a supernatural ability.
