Swallowed M80 is an unlockable trinket added in The Binding of Isaac: Repentance.
Effects[]
- Isaac has a 50% chance to explode when he takes damage, similarly to if he used
Kamikaze!.
- The explosion deals 185 damage and uses most of Isaac's bomb synergies.
- The explosion does not cause additional damage to Isaac.
Notes[]
- Causes Devil Beggar and Hell Game to become essentially unplayable, as any damage that could trigger Swallowed M80 will likely cause Isaac to explode, killing them.
- Causes Blood Donation Machines and Confessionals to act as if they were destroyed from the explosion despite surviving and functioning normally, resulting in extra coin and Heart drops.
- The explosion cannot be triggered by Curse Room or Sacrifice Room spikes.
Synergies[]
- Golden Trinket / Mom's Box / Swallowed M80: Having either of these effects/another copy of the trinket raises the chance to trigger an explosion to 100%.
- Pyromaniac: Heals half a red heart on triggered explosion, rendering Isaac invincible on earlier stages if combined with the above synergy.
Interactions[]
- Tainted Magdalene: Explosions will kill enemies before Tainted Magdalene's “hug” attack, preventing heart drops from killing enemies on contact from being guaranteed.
No Effect[]
All bomb upgrades affect Swallowed M80 except the following:

Trivia[]
- This item is a reference to M-80 firecrackers.[1]
- The inability to properly destroy Blood Donation Machines and Confessionals with this trinket was unintended, but kept in as a feature.[2]
