Nullify

Schools:	Translocation

  You undo the last action which the target performed, rolling back any impact the action had as though the action was never performed. The cost of undoing the action is equal to total amount of points invested in that action. Nullify can only be performed on the last action performed. Nullify is considered a 'counter-attack' and can be performed in response to any action.  

Lesser Nullify

Costs half as much as Nullify. You may only undo actions which directly involve you or actions performed to unsuccessfully navigate hazards.  

Greater Nullify

Costs twice as much as Nullify. When rolling back an action, you may choose to directly affect its outcome instead as though interfering with Mage Hand, using all the rules normally associated with Mage Hand.
