In-game pickup line
“Blood laser barrage”
Mechanics
What Brimstone does
- Hold fire to charge a piercing blood beam that hits enemies along its path.
- The base item applies a 0.33 fire-rate multiplier; a full beam deals damage over its duration rather than in one instant.
- Its listed full-beam damage in Repentance is nine times Isaac’s damage across about 0.63 seconds, before other item interactions.
In a run
Practical note
Line enemies up before firing. The continuous beam can hit several targets, but the charge slows repeated shots.
