Arcane Gunpowder

How to use it

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

1. In the Black Powder Mine (floor 3), find the big, seemingly empty room full of floating minecarts over a chasm.
2. Ride the carts across on their invisible rails, dodge rolling from cart to cart. Rolling into a cart seats you in it; slow one down to line up the next jump.
3. Grab the Gunpowder on the far side and carry it to the Blacksmith in the Forge.

Don't lose it

• It's the only active-item part, so it takes up an active slot — The Pilot's extra slot helps.
• Any flight item lets you skip the minecarts entirely.
• Falling into the pit resets the room and deletes anything you dropped there.
• In co-op, it vanishes if whoever holds it dies. The Rat can't steal 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.
