Shard of Glass

Upon taking damage, Isaac has a chance to drop a full red heart, gain 5 range, and leave a trail of damaging red creep for the current room. Taking damage causes Isaac to bleed, spraying a volley of blood in the direction he fires. Bleeding will eventually damage him, but it can be stopped by picking up a Red Heart.

Effects

• Adds a 25% chance to drop a full Red Heart upon taking damage.
• Taking damage will cause Isaac to bleed, spewing red tears around him constantly.
• • If the bleeding goes for too long, Isaac's Red Hearts will take damage (bypassing other Hearts); this is indicated by Isaac slowly turning red and eventually blinking. This damage has a large chance of dropping a full Red Heart.
  • • Red Hearts spawned by this item may become different hearts in certain Super Secret Rooms.
  • Holding a direction of fire focuses the bleeding to that direction, with slightly increased range.
  • Shard of Glass's effect ends when Isaac receives any form of Red Heart healing, if Isaac loses his last Red Heart, or if the next hit would kill Isaac.
  • • The Forgotten can end the bleeding by switching to The Soul.
  • If Isaac has no Red Hearts, the effects of Shard of Glass will not activate.
