Fortune's Aegis (3.5e Maneuver)

The ultimate defense for a Coin’s Edge, by invoking fortune’s aegis you leave a foe with only the worst of all possible attacks to use against you.

You may initiate this maneuver whenever an enemy attacks you, after they have made their attack roll. This maneuver replaces the result of their attack roll with a 1. If the new result does not exceed your AC, the attack misses. As this 1 is not a natural 1, the attack does not automatically miss. This maneuver is a supernatural ability.
