Brimstone Bombs is a passive item added in The Binding of Isaac: Repentance.
Effects[]
- Gives Isaac +5 bombs.
- Upon exploding, Isaac's bombs fire 4
Brimstone lasers in the cardinal directions.
- Each laser deals 8 damage per tick, and can hit up to 19 times.
- Multiple lasers cannot hit the same enemy simultaneously.
Notes[]
- The lasers created by Brimstone Bombs can push other bombs, including Troll Bombs and bombs placed by Isaac.
Synergies[]
- BBF/ Bob's Brain: Inherits the effect in full, firing lasers every time they explode.
- Dr. Fetus/ Epic Fetus: Attacks have a small chance to trigger this effect. Chance goes up to 100% at 30 luck.
- Kamikaze!: Activating Kamikaze! sends brimstone lasers in all 4 directions.
- Locust of War/ Scatter Bombs: Explosions create thinner lasers that deal 4.8 damage per tick instead of 8.
- The Mulligan/Guppy: The lasers can create Blue Flies when they deal damage.
- Multidimensional Baby: Placing Multidimensional Baby in front of the beam will transform it into two black-and-white beams.
Interactions[]
- Bomber Boy: Only the center explosion will fire lasers.
- Anarchist Cookbook: The lasers fired by the troll bombs will push other troll bombs around, likely to the edges of the room.
