You weave the fortunes of others around your ally as a shield, siphoning off your foe's luck and making it theirs. Roll a number of ten-sided dice equal to your level, and set them aside. Whenever a foe attacks your protected ally, if any of their dice rolled for the attack roll matches any of the dice you rolled and set aside, discard one matched die from your reserve, and some remarkable bit of bad luck caused your foe's attack to miss. You cannot Cast this Spell again until all the dice in your reserve are used up, or until you Take a Long Rest. When this spell ends, discard any dice remaining in the reserve.

Note that the dice reserve for this spell is private to this spell alone, and is not shared with the dice reserve for any other spell or action.
