Effects[edit | edit source]

  • On use, Isaac holds a key above his head. Pressing a fire button removes one key and throws it as a piercing projectile. The key damages enemies, as well as opens locked doors and chests it hits.
    • The key will also break the first rock it hits.
    • The thrown key does damage equal to 5x Isaac's damage + 30.
  • Gives 5 keys when picked up for the first time on a run.

Notes[edit | edit source]

  • Thrown keys can open the door to Mom's Heart, the door to Mega Satan, the door to access Mausoleum and the Strange Door. However, it cannot be used as a substitute for the Red Key.
  • Thrown keys can be used to open secret rooms.
  • Destroying a rock will create a bridge at the opposite side the thrown key hit from.
  • One thrown key can open doors that require two keys to open.
  • Despite being a substitute to bombs, thrown keys will not destroy shopkeepers.
  • Thrown keys can open multiple chests.
  • Thrown keys can't open locked Challenge Rooms.
