Brimstone is a special passive item.

Effects[edit | edit source]

  • Isaac's tears are replaced with a charged blood laser beam. The beam is piercing and spectral, dealing damage to all enemies and ignoring all obstacles in its path.
    • The laser deals damage equal to Isaac's damage and deals damage each tick.
      • Removed in Repentance Brimstone ticks 13 times over the course of about 1 second.
      • Added in Repentance Brimstone ticks 9 times in about 1 second.
    • Tears down: Delay * 3.
  • Added in Afterbirth / Removed in Repentance This item belongs to the Leviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes[edit | edit source]

  • Azazel starts the game with a short-ranged, slower charging version of Brimstone. Picking up Brimstone with him will give him the long-ranged version. Without the long-range version, his mini-brimstone won't have enough length to use any homing items.
    • Added in Afterbirth His Brimstone's shorter range can be increased with range up items or pills.
  • Multi-shot effects like 15►20/20 20/20 will increase the number of beams accordingly, with exceptions listed below.
    • Although extremely unlikely, Isaac can shoot a total of 16 blood beams at a time via multi-shot items. If the number of blood beams would exceed this number, the beams' span will instead widen.
  • Added in Afterbirth / Removed in Repentance If multiple Brimstones are picked up (via Added in Afterbirth15►Diplopia Diplopia, Added in Afterbirth †15►Crooked Penny Crooked Penny or on a Victory Lap), then another beam is added, with no increase in charge time.
  • The beam will apply status effects and does so frequently thanks to its high tick rate.
  • Added in RepentanceTainted Azazel picking it up won't make character's attack wider unless it is picked up twice.

Synergies[edit | edit source]

  • Added in Afterbirth15►8 Inch Nails 8 Inch Nails: Beams gain knockback, pushing enemies away in the direction they travel but not out of their path. This increases its consistency.
  • Added in Repentance15►Almond Milk Almond Milk: Brimstone can be used without charging and will last indefinitely. The beam will also gain random worm trinket effects. Damage is significantly decreased. The beam can also be aimed in any direction with joystick controls.
  • Added in Afterbirth †15►Apple! Apple! / Added in Afterbirth †15►Euthanasia Euthanasia / 15►Tough Love Tough Love: The beam can gain the damage multiplier from each of the items, although there is no visual difference. The bonus applies for the whole beam and not on a per-tick basis. Euthanasia loses its instant kill ability, however.
  • 15►Anti-Gravity Anti-Gravity: An orb of energy expands, then shrinks while firing the beam after a delay. The orb still hurts enemies if they touch it. Isaac can start charging a new shot immediately after releasing the fire key without canceling the first shot, effectively allowing for a faster firing rate. It makes it harder to hit enemies with Azazel as the beam does not increase in range.
    • Added in Afterbirth Anti-Gravity + Added in Afterbirth15►Incubus Incubus: Isaac will fire Brimstone orbs, while Incubus will fire regular Brimstone beams.
  • Added in RepentanceBrain Worm Brain Worm: The beam will curve 90 degrees in order to attack opponents, effectively acting as a stronger form of homing.
  • Added in Repentance15►Compound Fracture Compound Fracture/15►Cricket's Body Cricket's Body: Non-brimstone tears have a chance to split off from the beam with applicable stats and tear effects.
  • Added in Repentance15►Chocolate Milk Chocolate Milk: Brimstone laser takes longer to fully charge, but can be released at any point during its charge. Width and damage of the laser increases at higher charges.
  • Added in Repentance15►Crooked Penny Crooked Penny/15►Diplopia Diplopia: Second Brimstone grants a much larger beam with a 1.2x damage multiplier and +1 damage. Any further Brimstones picked up will only grant +1 damage.
  • Added in Afterbirth15►Epic Fetus Epic Fetus: Overrides Brimstone's charging effect, but missile explosions shoot ten beams in all directions, massively increasing damage and area of effect.
  • Added in Repentance15►Explosivo Explosivo: The beam has a chance to stick explosive tears to enemies.
  • Added in Repentance15►Eye of the Occult Eye of the Occult: Brimstone will automatically charge, then attempt to hit the wall Isaac is facing before curving towards the crosshair.
  • 15►Fire Mind Fire Mind: The beam will not cause explosions, but will still set enemies on fire.
  • Guppy: Blue Flies are spawned at a rate of approximately one blue fly per tick of damage for each enemy it hits, up to 13 flies. The spawned blue flies will also move to attack the targeted enemy immediately.
  • Added in Afterbirth †15►Haemolacria Haemolacria: Increased charge time. Tears will burst into several beams that are fired in random directions.
  • Added in Repentance15►Holy Light Holy Light: The beam has a chance of summoning a row of Holy Light beams.
  • Homing tears: The beam will make sharp turns and even loops to hit enemies. Azazel's mini-brimstone does not home unless he has a high range stat.
  • Hook Worm Hook Worm: Beam shifts left to right while firing straight and forms angles that constantly flatten and expand, effectively increasing its width.
  • Added in Repentance15►Ipecac Ipecac: The beam gains a poison effect. Upon hitting an enemy, wall or obstacle, the beam causes an explosion. +2 flat damage. Fire rate is unaffected. 15►The Ladder The Ladder, when placed, will trigger the Ipecac-brimestone explosions.(possibly a bug)
  • Added in Repentance15►Jacob's Ladder Jacob's Ladder: Upon hitting an enemy, wall or obstacle, the beam generates sparks that home in on enemies.
  • 15►Loki's Horns Loki's Horns: Occasionally causes Isaac to fire the beam in all four cardinal directions, similarly to 15►Head of Krampus Head of Krampus's effect.
  • 15►The Ludovico Technique The Ludovico Technique: The beam forms a large ring that is controllable and does not need to be charged. Enemies inside the ring without touching it are not hurt. The shot speed is ignored. The tears stat is ignored and the damage is dealt very rapidly at a rate equivalent to a 2 tear delay.
  • Added in Afterbirth15►A Lump of Coal A Lump of Coal: The beam gradually increases in size and damage the farther it travels, with the damage increasing on a multiplier that is roughly +20% per tile of distance. This allows for a huge damage increase from longer distances.
  • Added in Repentance15►Marked Marked: Brimstone will automatically charge, then fire at the direction of the crosshair.
  • 15►Mom's Eye Mom's Eye: Adds a chance to shoot a beam from the back of Isaac's head.
  • 15►Mom's Knife Mom's Knife: Adds a small barrage of knives after the main knife is fired, with each knife doing 80% of Isaac's tear damage. The barrage of knives goes all the way across the screen and increases in quantity the longer the charge.
  • 15►Mom's Wig Mom's Wig: Holding down a fire button to charge the attack very rapidly rolls the probability to spawn blue spiders; releasing to fire the beam, however, does not.
  • Added in Afterbirth15►Monstro's Lung Monstro's Lung: Fires 3-5 additional Brimstone beams in random directions around Isaac with no increase in charge time. Charging a new Brimstone beam removes the original from in front of Isaac, but not the additional ones added by Monstro's Lung. This effectively increases the fire rate.
    • Added in Repentance Charging a new Brimstone beam will now remove all shot beams, but fire rate remains that of Brimstone.
  • Added in Repentance15►Ocular Rift Ocular Rift: Rifts may appear where the beam hits rocks, walls or enemies.
  • Added in Repentance15►The Parasite The Parasite: Upon hitting an enemy, wall or obstacle, two perpendicular beams split from the main beam at 90 degrees from the closest point of intersection.
  • Added in Afterbirth15►Rubber Cement Rubber Cement: Beams bounce off of walls, creating a second beam that deals half damage.
    • Added in Afterbirth If Azazel's mini Brimstone beam bounces off a wall, it effectively becomes a full-length Brimstone beam, but it will still only deal half damage.
      • Added in Afterbirth † Azazel's Brimstone no longer becomes a full length beam after bouncing, instead bouncing as a regular mini-Brimstone.
  • 15►Sad Bombs Sad Bombs: Upon exploding, bombs release ten beams in all directions.
    • Added in Repentance Brimstone does not benefit from Sad Bombs's flat damage bonus.
  • Added in Repentance15►Sinus Infection Sinus Infection: The beam has a chance to stick booger tears to enemies.
  • Added in Repentance15►Sulfuric Acid Sulfuric Acid Beams has a chance to destroy rocks every tick.
  • Added in Repentance15►Soy Milk Soy Milk: Brimstone can be used without charging and will last indefinitely. Damage is significantly decreased.
  • 15►Strange Attractor Strange Attractor: Enemies are attracted towards the beam, improving its consistency. Consumables will also be moved by the beam.
  • Added in Repentance15►Sulfur Sulfur: Grants a larger beam with a 1.2x damage multiplier and +1 damage (same effect as picking up a second Brimstone).
  • 15►Tammy's Head Tammy's Head: Shoots ten beams in all directions. Given the item's single room charge, this makes for an extremely powerful synergy.
    • Added in Repentance Brimstone does not benefit from Tammy's Head's flat damage bonus.
  • Added in Afterbirth15►Technology Technology: The Technology laser coils around the Brimstone beam, granting a 1.5x damage multiplier (it stacks with other similar multipliers like 15►Cricket's Head Cricket's Head or 15►Magic Mushroom Magic Mushroom).
    • Added in Repentance Technology's damage multiplier will be overriden if Isaac has the powered up version (from picking up Brimstone twice or using Added in Repentance15►Sulfur Sulfur with Brimstone).
  • Added in Afterbirth15►Tech X Tech X: Brimstone becomes a large laser ring that varies in size depending on how long it is charged before firing. The tear delay is that of Tech X.
    • Tech X + 15►A Lump of Coal A Lump of Coal: The Brimstone ring increases in size and damage the further it travels.
    • Tech X + 15►Mom's Knife Mom's Knife: Mom's Knife and a Mom's Knife+Brimstone barrage are shot alongside the rings.
  • 15►Tiny Planet Tiny Planet: The beam will wrap around Isaac once and then shoot straight forward.
  • Added in Repentance15►Uranus Uranus: The beam has a chance to freeze any enemies hit, so long as they are not immune to the freeze effect.
  • Wiggle Worm Wiggle Worm: Beam becomes wavy while firing straight, effectively increasing its width.
  • Greatly decreases attack speed for Tainted Samson's rage mode melee attack and replaces the thrown jawbone with a large laser sphere.

Trivia[edit | edit source]

  • The term brimstone (burn stone) comes from the King James Bible's mention of burning sulfur. It is used in the phrase "fire and brimstone" to describe the torments of hell. While solid sulfur is yellow, molten sulfur is blood red.
  • Brimstone's item icon originally comes from the alchemical symbol for sulfur, referred to as the Leviathan Cross. It was later adopted by Anton LaVey in The Satanic Bible to represent hell and is now often associated with Satanism.
  • The ram horns gained from picking up Brimstone were added as a cosmetic item to Team Fortress 2 to promote The Binding of Isaac: Rebirth. If the game was purchased before the 10th of December, players were awarded the item in genuine quality.
  • Most items that change tear color will also give Brimstone an exotic appearance, but they do not combine and only one color effect is shown.

Bugs[edit | edit source]

Bug Bug! Removed in Repentance Picking up Brimstone before picking up Scorpio will not change the beam's color. Picking up Scorpio before Brimstone, however, will properly change it to green.
Bug Bug! Added in Repentance When having Brimstone + My Reflection and facing towards a wall, standing directly in front of it will make Isaac shoot in reverse - the front facing oval Brimstone beam will shoot from the back, and the back facing beam will shoot from the front.
