Alternate Reality

You tamper with an event from within the last couple of seconds, potentially changing the outcome. You can cast this spell after one attack roll, saving throw, or ability check is made on the current turn. Events are reset to the moment the target made that roll. The target makes that roll again, with the same modifiers as before, and gains your choice of either advantage or disadvantage on the reroll but must take the new result. All creatures involved remember how it played out before the spell was cast.
