Only usable when this vampire successfully blocks an ally or younger vampire bleeding you.
[dem] Put this card on the acting minion and end the action (with no combat). The minion with this card gets -1 bleed. He or she may burn it as an action that costs 1 blood. A minion may have only one Shattered Mirror.
[DEM] As above, and this reacting vampire doesn't tap for successfully blocking the action.
