Upon use, summons a sword that hangs directly above Isaac. As long as the sword hangs above Isaac, all item pedestals and items spawned from Beggars are doubled, spawning an additional, free item next to them.
After Isaac gets hit once with the item activated, at any time without warning, the sword may fall, instantly killing Isaac regardless of his health. The more hits Isaac takes, the more likely it becomes for the sword to fall.
Self-damage (such as from a Blood Bank, Devil Beggar, Curse/Sacrifice room, or self-damage Active Items) does not increase the chance for the sword to fall.
