Binding of Isaac: Rebirth Wiki

Brimstone is a passive item.

Effects[]

  • 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.
      • These ticks occur every 1/15th of a second (once every 4 frames). However after the first damage tick, there is an additional pause for ~0.12 seconds (7 frames). Damage ticks work normally after that.
      • Removed in Repentance Brimstone ticks 13 times over the course of 0.9 seconds (54 frames).
      • Added in Repentance Brimstone ticks 8 times in ~0.57 seconds (34 frames).
    • Tears down: Delay * 3.
  • Added in Afterbirth / Removed in RepentanceThis item belongs to the Leviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes[]

  • Removed in Repentance Brimstone is a special item.
  • Azazel 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.
  • The beam will apply status effects and does so frequently thanks to its high tick rate.
  • 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.
    • Added in Repentance Picking up a second Brimstone will give +1 damage, 1.2x damage multiplier, as well as make the laser beam 2x wider with no increase in charge time. Picking up additional copies of Brimstone will only add +1 damage.
      • If combined with Azazel's Added in Repentance15►Birthright Birthright effect, the laser beam will be 4x wider.
      • The bigger beam granted by double Brimstone synergizes with other items as expected.
  • Added in RepentanceTainted Azazel Tainted Azazel's beam width and damage will not be increased unless picked up twice, or with Chocolate Milk.

Synergies[]

  • 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 Azazel as the beam does not increase in range.
    • Added in Repentance Anti-Gravity + 15►Soy Milk Soy Milk: The Brimstone orbs remain as long as the fire button is held, similarly to Brimstone + Soy Milk but fixed in place. Isaac is unable to charge another shot while it is firing.
    • Added in Afterbirth Anti-Gravity + Added in Afterbirth15►Incubus Incubus: Isaac will fire Brimstone orbs, while Incubus will fire regular Brimstone beams.
  • Azazel Azazel + Added in Repentance15►Birthright Birthright: The Brimstone beam will have its width doubled as per the effect of Azazel's version of Birthright. Stacked with other beam widening synergies like Brimstone and 15►Chocolate Milk Chocolate Milk, it can lead to a Brimstone blast that dwarfs even the Added in Afterbirth15►Mega Blast Mega Blast in size, allowing for quick and easy room clears through the sheer size of the Brimstone beam.
  • Added in Repentance15►Bird's Eye Bird's Eye: Will occasionally spawn a fire when firing and with high luck will spawn four fires.
  • 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. Very strong against multi-segment bosses such as Mother.
  • 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►Continuum Continuum: Brimstone laser travels through the wall and appears out the other side once.
  • Added in Repentance15►Crooked Penny Crooked Penny/Added in Repentance15►Diplopia Diplopia: Picking up a 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►Multidimensional Baby Multidimensional Baby: If a brimstone laser is shot through the baby, it will double the laser.
  • 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.
  • Removed in Repentance Added in Afterbirth †15►Ghost Pepper Ghost Pepper: The flames can still shoot from Isaac while holding the fire button.
    • Added in Repentance Occasionally emits a flame while the beam is firing.
  • Guppy: Blue Flies are spawned at a rate of approximately one blue fly per tick (Added in Repentance every other 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 Repentance Fires bursting brimstone tears at the tears rate without any charging.
  • 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 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-brimstone explosions.(possibly a bug)
  • Added in Repentance 15►Jacob's Ladder Jacob's Ladder: Upon hitting an enemy, wall or obstacle, the beam generates sparks that home in on enemies.
  • Added in Repentance15►Knockout Drops Knockout Drops: Gives the lasers high knockback.
  • Added in Afterbirth †15►Large Zit Large Zit: Creep shots will still be fired occasionally while holding the fire button.
  • Added in Repentance15►Lodestone Lodestone: Changes the beam to gray, can still apply the magnetized effect. The beams are not attracted to enemies with the magnetized effect.
  • 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►Mucormycosis Mucormycosis: Will occasionally spawn spores.
  • Added in Repentance15►Ocular Rift Ocular Rift: Rifts may appear where the beam hits rocks, walls or enemies.
  • Added in Repentance Added in Afterbirth †Ouroboros Worm Ouroboros Worm: The beam will make large loops on itself. The homing is present, but very wonky.
  • 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 Repentance15►Rotten Tomato Rotten Tomato: Firing can mark enemies.
  • Removed in Afterbirth15►Rubber Cement Rubber Cement: Overridden by Brimstone.
    • Added in Afterbirth Beams bounce off of walls, creating a second beam that deals half damage.
      • Added in Afterbirth / Removed in Afterbirth † If Azazel 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 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' flat damage bonus.
  • Added in Repentance15►Sinus Infection Sinus Infection: The beam has a chance to stick booger tears to enemies.
  • 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).
  • Added in Repentance15►Sulfuric Acid Sulfuric Acid/Added in Repentance15►Terra Terra The beam has a chance to destroy rocks every tick.
  • 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 anymore.
  • 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 overridden 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►The Inner Eye The Inner Eye: Isaac fires three beams at once. Fire rate is decreased.
  • 15►Tiny Planet Tiny Planet: The beam will wrap around Isaac once and then shoot straight forward.
  • Added in Repentance15►Uranus Uranus: The beam will freeze any enemies killed by it, 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.

    • Added in Afterbirth Adds a second Brimstone.
  • Removed in Repentance15►Chocolate Milk Chocolate Milk: Reduces Isaac's tear delay by 20%. Doesn't increase damage.
    • Added in Repentance 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. Width scales from 50% at minimum charge to 160% at maximum charge. Damage scales from 25% at minimum charge to 250% at maximum charge. Unlike with normal tears, the tears stat does not directly affect maximum or minimum damage.
  • Removed in Repentance15►Compound Fracture Compound Fracture/15►Cricket's Body Cricket's Body/15►The Parasite The Parasite: Splitting is overridden by Brimstone, but stat effects are still applied.
  • Added in Afterbirth / Removed in Repentance15►Continuum Continuum: Overridden by Brimstone.

  • Added in Repentance15►Dr. Fetus Dr. Fetus: Overrides Brimstone.

    • Added in Afterbirth: Adds a Brimstone Sad Bombs effect: missile explosions shoot ten beams in all directions, massively increasing damage and area of effect.
  • Added in Afterbirth15►Epiphora Epiphora: Effect only activates when holding charge in a specific direction, and deactivates when the charge is released, effectively making Epiphora useless unless Isaac has exceedingly high tear delay.
    • Added in Repentance After charging an attack, continuing to hold the attack button will increase fire rate but the firerate is reverted when letting go of the attack button or changing the attack direction.
  • Added in Afterbirth15►Evil Eye Evil Eye: Overridden by Brimstone.

  • Removed in Afterbirth †15►Ipecac Ipecac: Isaac gains only the poison effect without either the increased damage nor the decreased fire rate.
    • Added in Afterbirth † / Removed in Repentance Isaac shoots Ipecac tears while charging Brimstone. Both Brimstone and Ipecac shots modify Isaac's damage and tear delay stat, meaning that Ipecac fires slower and Brimstone charges slower, but Brimstone deals drastically increased damage. Take care to pre-charge Brimstone so that the Ipecac shot is on cooldown as Isaac enters a room.

  • Added in Afterbirth †15►Technology Zero Technology Zero: Overridden by Brimstone.
  • Removed in Afterbirth15►Technology 2 Technology 2: Overridden by Brimstone, but retains the reduced damage.

Trivia[]

  • 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.
  • Added in Repentance Brimstone is one of the few items in the game that change Isaac's appearance if he has multiple copies of it.
  • Removed in RepentanceBrimstone has the same appearance of 15►The Pact The Pact, but with big, curved horns.

Bugs[]

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.
