Aura of Chaos(Tome of Battle: The Book of Nine Swords, p. 57)
Devoted Spirit (Stance) [Chaos]
Level: Crusader 6 (Two Devoted Spirit maneuvers),
Casting Time: 1 swift action
A coruscating aura of purple energy surrounds you as chaos runs rampant in the area immediately around you.
While you are in this stance, your attacks have the potential to be utterly devastating. When rolling damage for a melee attack, you gain a special benefit from any damage die that rolls its maximum amount (such as a result of 6 on a d6). When one or more of your damage dice show a maximum possible result, reroll each such die and add its result to the original damage total. You can continue to reroll as long as a die shows its maximum possible result, adding each new number to the damage total until each die has shown less than a maximum result.
