CASTING

Casting Time 1 swift action

EFFECT

Range personal
Target you
Duration instantaneous

At any point during your turn, you may cast this spell to slip backwards in the time stream, undoing any actions you have taken so far during that turn and erasing their effects. Any actions by other creatures that occurred reactively during your turn as a result of your actions, including attacks of opportunity and readied actions, are similarly undone and their effects negated. Resources expended for any actions negated by the paradox are restored to their unused condition, including spells cast, daily uses of abilities, consumable magic items or charges, or anything else, as though they had never been used. You cannot alter any action or its effects that occurred prior to your current turn, and you cannot cast this spell if you have already been affected by an effect that prevents you from taking actions or casting spells.
