Effects

  • 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.
