Prime Primer

How to use it

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

1. Buy it from the shop in the Gungeon Proper (floor 2) for 110 money. Shop discounts don't apply.
2. Keep it until the Forge and give it to the Blacksmith along with the other three parts.

Don't lose it

• Stealing it isn't worth it — surviving Bello's attack closes the shop and the Primer vanishes.
• It sits in a glass case, so the Grappling Hook can't snag it.
• 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.
