Warrior's Fate (3.5e Maneuver)

Through mystical probability meditations, Coin’s Edge adepts can tap into a moment of chance, whether good or bad, calling on its probabilities to evoke later.

When you initiate this maneuver, roll 1d20, and record the result. Once during the rest of the encounter, you may choose to, after rolling a d20, replace the result with the result from this ability, as if you had rolled it instead. However, if you roll a 20, and later substitute it, it does not count as a natural 20, and thus does not automatically hit if substituted on an attack roll, nor does it trigger results dependent on a natural 20, such as the vorpal weapon ability. You may not recover this maneuver until you discharge the stored result. This maneuver is a supernatural ability.
