Casting Time 1 immediate action
Your limited omniscience allows you to reroll a saving throw, attack roll, or skill check. The skill check cannot take more than 1 round. Whatever the result of the reroll, you must use it even if it is worse than the original roll. If you use the power to reroll a saving throw, you can cast this spell even when it is not your turn.
