How to use it

One of the four parts of the Bullet That Can Kill The Past.

  1. Beat the High Dragun at the end of the Forge.
  2. Shoot its skull to break it and pick up the Casing.
  3. Give it to the Blacksmith with the other three parts.

Don't lose it

  • The Rat never steals it, and it can't be dropped once picked up.
  • It's the only part you can get again after handing it over.
  • You need all four parts — Prime Primer, Planar Lead, Obsidian Shell Casing, and Arcane Gunpowder — in one run before the Blacksmith will forge the Bullet That Can Kill The Past.
  • Hand everything to the Blacksmith in the Forge (floor 5); the finished Bullet then lets you fight your character's Past in the Breach.
  • Bullet parts can't be dropped, so The Cultist in co-op can never deliver them — have the main player collect them.
