Aura faint evocation; CL 5th
Once per day, this good luck charm allows the wearer to reroll a single skill check or concentration check after the success or failure of the original roll is known. The result of the reroll must be kept, even if it is worse than the original roll. The charm may not be used on a skill check that’s already been rerolled by some other means.
