Copper Wrench is a passive item in Fiend Folio: RELOADED, a mod for The Binding of Isaac.

Spawns 3 Copper Bombs.

Increases the chance of Copper Bombs appearing by 20%.

If a Copper Bomb fails to blow up, it will turn into a Copper Bot Fly familiar.

The familiar behaves exactly like a Bot Fly.

After 60 seconds, the Bot Fly familiar gets primed and will serve as a one-time-use Holy Mantle shield for Isaac, after which it explodes, dealing 50 damage.

When primed, the Bot Fly no longer shoots tears.

Copper Bot Flies have a 0.33% chance to break every second.

Copper Wrench can be found in the following item pools:
