Gloves of Fortunate Striking

Best worn by the cleverest of warmakers, these gloves allow their wearer to attempt to change an unfortunate strike at the enemy to a more accurate one. Once per day, after the wearer of the gloves has made an attack roll (but before it's determined whether the roll succeeded), he may choose to make the attack roll again. He must use the second result even if it's lower. The wearer can't use this ability if he has already made the attack roll again because of another ability he possesses, nor can he use another ability he possesses to make the attack roll again as he uses the gloves. The gloves can be used only after they are worn continuously for 24 hours. If they are taken off, they become inactive until they are again donned and worn for a full 24 hours.
