You sort through the multiverse of infinite probabilities and phase shift yourself or your target into one that suits your purposes. For any action within the round this spell is cast, you may roll twice and take the result of your choosing. For each roll you alter in this way, you may spend MP equal to the difference between the dice rolled (if you are choosing between a 6 and a 3, the MP cost is 3) to replace a roll in this way. You may cast this spell as a reaction once during the round, in addition to any other action you take.

You shatter the fundamental relationship between cause and effect in the area of effect. All those who do not resist the spell are subject to random mishaps that exchange causes for effects. Every round the spell is in effect, victims have a 50% chance of all their actions affecting unintended targets. The spellcaster is unaffected.

You manifest the existence of a phantasm with tangibility in the area of effect, but by default only you and the targets of the spell believe in its existence. All others must make an opposed spell check to believe. For example, you create a phantasm of a bridge that only you and your party perceive to be real; all others may not cross it unless they succeed in an opposed spell check against you and have reason to believe it exists.
