Effects

• Upon use, sacrifices up to 2 familiars and spawns an item from the Devil Room pool for each familiar sacrificed.
• • The order in which the familiars were obtained does not matter; it picks 2 at random to sacrifice.
  • If Isaac has no familiars, no Blue Flies and no Blue Spiders, the item will do nothing and will not be consumed.
  • If the Devil Room pool has no items left, one or two copies of Pentagram are spawned.
  • When playing Greed mode the normal Devil Room pool is still used, instead of the Greed mode pool.
• In addition to the familiars, any Blue Flies or Blue Spiders will be converted to 1 Penny each.
