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.
    • Brimstone ticks 13 times over the course of 0.9 seconds (54 frames).
    • Brimstone ticks 9 times in ~0.63 seconds (38 frames).
  • ${\text{Charge Time (s)}}={\frac {1}{30}}(Roundup({\text{Tear Delay)}})\approx {\frac {1}{\text{Fire Rate}}}$
  • Starting from 15.00 fire rate, the beam can last indefinitely as long as fire key is held, and higher fire rate results in higher damage and larger scale.
    • ${\text{Damage per Tick}}={\frac {6\times {\text{Damage}}}{{\text{Tear Delay}}+1}}={\frac {{\text{Damage}}\times {\text{Fire Rate}}}{5}}$
• Tears down: Tear Delay × 3 / Fire Rate ÷ 3.
• This item belongs to the Leviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes

• Brimstone is a special item.
• Azazel starts the game with a short-ranged, slower charging version of Brimstone. Without the long-range version, his mini-brimstone won't have enough length to use any homing items.
  • His Brimstone's shorter range can be increased with range up items or pills.
• Multi-shot effects like 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 Tear effects and does so frequently thanks to its high tick rate.

Synergies

• Almond Milk: Fires automatically upon reaching full charge. The beam lasts indefinitely as long as the fire key is held. The beam can change its direction while being fired, and can be aimed in any direction with joystick controls. The beam will also gain random worm trinket effects.
  • Increasing tears stat will increase damage and width brimstone as well.
    • Damage per Tick = Damage × Fire Rate ÷ 5
• Azazel / Tainted Azazel: Picking up Brimstone with him will give him the regular version.
• Apple! / Euthanasia / 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.
  • The bonus applies randomly on every tick of the beam, including the insta-kill ability from Euthanasia.
• 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. Size and damage of the beams no longer scale with fire rate as well as lasting infinitely at above 15 fire rate.
  • Anti-Gravity + Soy Milk / Almond Milk: Allows auto firing upon full charge but without permanent beam uptime.
  • Anti-Gravity + Incubus: Isaac will fire Brimstone orbs, while Incubus will fire regular Brimstone beams.
    • Both Isaac and Incubus fire Brimstone orbs.
• 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.
• Brimstone:
  • Additional copies of this item, such as from Diplopia / Crooked Penny adds another beam, with no increase in charge time.
  • Additional copies of this item grant 1.2x damage multiplier and +1 damage and doubles the beam's width. Any further Brimstone only grants +1 damage.
    • If combined with Azazel's Birthright effect, the laser beam will be 4x wider.
    • The bigger beam granted by double Brimstone synergizes with other items as expected.
• C Section: Shoots 4 fetus tears along with the brimstone beam
  • The Ludovico Technique: Fetus tears no longer fire with Brimstone circle, even on doing damage.
• Chocolate Milk: Brimstone laser takes longer to fully charge but can be released at any point. Width and damage of the laser increases with charge, from 25% damage and 50% width at minimum charge to 250% damage and 160% width at maximum charge.
• Dataminer: Dataminer can be used to underflow Isaac's tears to immediately bring it to 120, maxing out Brimstone's width and damage via tears.
• Multidimensional Baby: If a brimstone laser is shot through the baby, it will double the laser.
• Eye of the Occult: Fires automatically upon reaching full charge. The beam curves towards the crosshair and then attempts to hit the wall Isaac is facing.
• Guppy: Blue Flies are spawned at a rate of approximately one blue fly per tick ( 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.
• Haemolacria: +20 Tear Delay after Haemolacria's tears down. Tears burst into 4-7 Brimstone beams that do Isaac's damage per tick.
  • Azazel/ Tainted Azazel: Overrides these characters' Brimstone. Tears do not burst into Brimstone beams.
  • Double Brimstone: Grants +1 Damage but not the 1.2x damage multiplier. The width of the beams doubles.
  • Haemolacria + Chocolate Milk: The Brimstone beams deal full damage regardless of charge.
  • Haemolacria + Technology: The lasers coil the beams. This is purely visual does not grant a 1.5x damage multiplier.
• 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: Beam shifts left to right while firing straight and forms angles that constantly flatten and expand, effectively increasing its width.
• Loki's Horns: Adds a chance to shoot a beam from all four cardinal directions, similarly to Head of Krampus's effect.
• The Ludovico Technique: The Ludovico Technique has priority. The beam forms a large ring that is controllable and does not need to be charged. The damage is dealt 15 times per second, unaffected by Tears. Enemies inside the ring without touching it are not hurt.
  • The Ludovico Technique + multi-shot effect: No effect.
  • The Ludovico Technique + C Section: Disables C Section. Fetuses no longer spawn.
  • The Ludovico Technique + Incubus:
    • Incubus' Brimstone laser is not affected by Ludovico Technique.
    • Adds a smaller controllable laser ring in addition to the main one.
  • The Ludovico Technique + A Lump of Coal: The ring increases in diameter on distance. 100% when he is on the center, 1.25x when he is 12.5 tiles of distance away.
    • The damage does not increase on distance.
    • The damage increase 20% per tile of distance.
  • The Ludovico Technique + Mom's Knife: Overrides Brimstone.
  • The Ludovico Technique + Proptosis: The ring increases in diameter when Isaac is closer; 1.25x when he is on the center, 100% when he is 12.5 tiles of distance away.
    • The ring deals 1.5x Isaac's Damage at its largest, and 50% at its smallest.
• 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 +20% per tile of distance. This allows for a huge damage increase from longer distances.
• Mom's Eye: Adds a chance to shoot a beam from the back of Isaac's head.
• Mom's Knife: Mom's Knife has priority. Does not apply Brimstone's tears down. Adds a small barrage of knives after the main knife is fired, with each knife doing 80% of / 2x Isaac's tear damage. This effect does not work with Azazel's Brimstone.
  • The barrage of knives goes all the way across the screen and does not return.
  • Charge amount increases the barrage size; 2-4 knives at 0%, 8-10 knives 100%.
• 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.
• My Reflection:
  • Overridden by Brimstone.
  • Makes the beam curve when moving. It has the same effect on Azazel's mini-brimstone but doubles the range.
  • Makes the beam shoot from the back. An oval beam is shot from the front instead.
• Ocular Rift: Rifts may appear where the beam hits rocks, walls or enemies.
• Ouroboros Worm: The beam will make large loops on itself. The homing is present, but unreliable.
• Sad Bombs: Upon exploding, bombs release ten beams in all directions.
  • Brimstone does not benefit from Sad Bombs' flat damage bonus.
• Soy Milk: Fires automatically upon reaching full charge. The beam lasts indefinitely as long as the fire key is held. The beam can change its direction while being fired, and can be aimed in any direction with joystick controls.
  • Increasing tears will also increase damage.
    • Damage per Tick = Damage × Fire Rate / 5
  • Soy Milk + Chocolate Milk: The beam does 25% more damage. Does not increase Isaac's damage stat itself.
• Strange Attractor: Enemies are attracted towards the beam, improving its consistency. Consumables will also be moved by the beam.
• Sulfur: Grants a larger beam with a 1.2x damage multiplier and +1 damage (same effect as picking up a second Brimstone).
• Tammy's Head: Shoots ten beams in all directions. Given the item's single room charge, this makes for an extremely powerful synergy.
  • Brimstone does not benefit from Tammy's Head's flat damage bonus anymore.
• Tech X: Tech X has priority. Does not apply Brimstone's tears down. Fires a Brimstone ring. This Brimstone ring is larger than the laser ring and has a much wider hitbox.
  • Double Brimstone: Further increases the width of the ring, and grants +1 Damage.
  • Tech X + Azazel:
    • Overridden by Azazel's Brimstone.
    • Overrides Azazel's Brimstone. This works quite well with Azazel's good initial damage stat and also negates his initial range penalty.
    • Applies 35% damage penalty and fires a Brimstone ring instead of Tech X ring. If combined with Brimstone, the damage penalty is negated.
      • The same applies to Tainted Azazel.
  • Tech X + Mom's Knife: Mom's Knife and a Mom's Knife + Brimstone barrage are shot alongside the rings.
  • Tech X + Technology: The 1.5x damage multiplier from Brimstone + Technology is lost, but the laser fires while charging the Brimstone ring.
    • Fires a Brimstone ring coiled by a laser. The 1.5x damage multiplier from Brimstone + Technology is retained.
• Tiny Planet: The beam will wrap around Isaac once and then shoot straight forward.
  • If combined with My Reflection, the beam will first wrap around Isaac, form an oval beam in a longer range, then shoot backward. Interestingly enough, the beam will look like a G clef symbol.
• Uranus: The beam will freeze any enemies killed by it, so long as they are not immune to the freeze effect.
• Wiggle Worm: Beam becomes wavy while firing straight, effectively increasing its width.

Interactions

• 20/20:
  • Overridden by Brimstone.
  • Adds a second Brimstone.
• 8 Inch Nails: Beams gain knockback, pushing enemies away in the direction they travel but not out of their path. This increases its consistency.
• Bird's Eye: Will occasionally spawn a fire when firing and with high luck will spawn four fires.
• Chocolate Milk: Reduces Isaac's tear delay by 20%. Does not increase damage.
• Compound Fracture: Splitting is overridden. The stat change is applied as normal.
• Continuum:
  • Overridden by Brimstone.
  • Brimstone laser travels through the wall and appears out the other side once.
• Cricket's Body:
  • Splitting is overridden. The stat changes are applied as normal.
  • Spawns split tears on the first enemy or obstacle the beam hits.
• Cursed Eye: Overridden by Brimstone.
• Dr. Fetus: Overrides Brimstone.
• Epic Fetus:
  • Overrides Brimstone.
  • Adds a Brimstone Sad Bombs effect: missile explosions shoot ten beams in all directions, massively increasing damage and area of effect.
• 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.
• Evil Eye: Overridden by Brimstone.
• Eye of Belial: Overridden by Brimstone.
• Explosivo:
  • Overridden by Brimstone.
  • The beam has 20% chance to stick explosive tears to enemies on every other tick.
• Fire Mind: The beam will not cause explosions, but will still set enemies on fire.
• Flat Stone: Overridden by Brimstone.
• The Forgotten: The charged attack will spawn a Brimstone ball that will float in front of The Forgotten for a few seconds before disappearing. The Forgotten will still melee attack while performing this action.
• Ghost Pepper:
  • The flames can still shoot from Isaac while holding the fire button.
  • Has a chance to shoot flames for every other tick while the beam is being fired.
• Godhead: Homing and stat bonuses apply, but the beam does not have a damaging aura.
• Head of the Keeper:
  • Overridden by Brimstone. Also applied to Azazel's Brimstone.
  • Makes the laser yellow and upon a tick has a chance to drop a coin. Also applied to Azazel's Brimstone.
• Holy Light:
  • Overridden by Brimstone.
  • Every tick of the beam has a chance of summoning a beam of light.
• Ipecac:
  • Does not apply Ipecac's stat changes. The beam poisons enemies.
  • Isaac shoots Ipecac tears while charging Brimstone. Stat changes from both items are applied as normal, meaning that Ipecac fires slower and Brimstone charges slower, but Brimstone deals drastically increased damage.
  • Applies +2 flat damage, intead of Ipecac's damage up. Does not apply Ipecac's tears down. The beam explodes on the first enemy or obstacle it hits every other tick, dealing 10 + twice of Isaac's Damage. The beam gains a poison effect. The explosions do not occur when the beam narrows, meaning that they occur only twice per shot without Soy Milk / Almond Milk. The beam and its explosions poison enemies. The Ladder, when placed, will trigger the Ipecac-Brimstone explosions. (possibly a bug)
• Isaac's Tears: Fires normal tears, but nearly instantly charges when charging Brimstone.
• Jacob's Ladder:
  • Overridden by Brimstone.
  • Upon hitting an enemy, wall or obstacle, the beam generates sparks that home in on enemies.
• Kidney Stone: Overridden by Brimstone.
• Knockout Drops: Gives the lasers high knockback.
• Lachryphagy:
  • Overridden by Brimstone.
  • Brimstone has shorter range, a bit longer than Azazel's brimstone, and it is not affected from Range. The beam fires Pop! tears at the end, which is Piercing.
• Large Zit: Creep shots will still be fired occasionally while holding the fire button.
• Lead Pencil:
  • Overridden by Brimstone.
  • Lead Pencil triggers approximately every 2 seconds as the beam is fired (charge time is not counted).
• Lodestone: Changes the beam to gray, can still apply the magnetized effect. The beams are not attracted to enemies with the magnetized effect.
• Marked:
  • Overridden by Brimstone.
  • Fires automatically upon reaching full charge. Fires at the direction of the crosshair.
• Monstro's Lung:
  • Overridden by Brimstone.
  • Brimstone has priority. Does not apply Monstro's Lung's tears down. Fires 3-5 additional beams in random directions around Isaac. This effect also applies to Azazel and Tainted Azazel's Brimstone.
    • Charging a new Brimstone beam removes the original from in front of Isaac, but not the additional ones added by Monstro's Lung.
• Mucormycosis: The beam has 25% chance to spawn spore to enemies on every other tick.

• Mysterious Liquid:
  • Overridden by Brimstone.
  • Leaves a creep for each enemy and obstacle the beam hits, on every other tick. Azazel's Brimstone leaves creeps at the end of its range.
• Neptunus: Overridden by Brimstone.
• Number One: Although Number One is otherwise purely beneficial with standard Brimstone, Azazel's range is severely affected.
• The Parasite:
  • Splitting is overridden. The stat changes are applied as normal.
  • Spawns two perpendicular beams on the first enemy or obstacle the beam hits.
• Parasitoid: Overridden by Brimstone.
• Pop!:
  • Overridden by Brimstone.
  • Brimstone has shorter range, a bit longer than Azazel's brimstone, and it is not affected from Range. The beam fires Pop! tears at the end, which is Piercing.
• Proptosis:
  • Does not apply distance penalty.
  • The beam deals 2x Isaac's Damage, which is already doubled from the items effect, at point blank range. The damage quickly drops further along the beam, at about 0.8x per tile of distance.
  • The beam deals 6x Isaac's Damage at point blank range. Decreases 13.3% of the damage per tile of distance, to the minimum of 0.1 point of damage at 7.5 tiles of distance.
• Pupula Duplex: Overridden by Brimstone.
• Rotten Tomato: Firing can mark enemies.
• Rubber Cement:
  • Overridden by Brimstone.
  • Beams bounce off of walls once, creating a second beam that deals half/ full damage.
    • 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.
    • Azazel's Brimstone no longer becomes a full length beam after bouncing, instead bouncing as a regular mini-Brimstone.
• Sinus Infection:
  • Overridden by Brimstone.
  • The beam has 20% chance to stick booger tears to enemies on every other tick.
• Spirit Sword: Overrides Brimstone.
• Sulfuric Acid:
  • Overridden by Brimstone. Stat effects are still applied.
  • The beam has a chance to destroy rocks every tick.
• Tainted Samson: Greatly decreases attack speed for Samson's rage mode melee attack and replaces the thrown jawbone with a large laser sphere (similarly to The Forgotten).
• Technology:
  • Overridden by Brimstone, but adds damage.
  • The Technology laser coils around the Brimstone beam, granting a 1.5x damage multiplier (it stacks with other similar multipliers like Cricket's Head or Magic Mushroom).
    • Technology's damage multiplier will be overridden if Isaac has the powered up version (from picking up Brimstone twice or using Sulfur with Brimstone).
• Technology Zero: Overridden by Brimstone.
• Technology 2:
  • Overridden by Brimstone, but retains the reduced damage.
  • Both fire normally; the Technology laser fires while charging Brimstone.
• Tech.5:
  • Overridden by Brimstone unless using Azazel, in which case it will fire normally while charging Brimstone.
  • Tech.5 fires normally while charging Brimstone.
• Terra: The beam has a chance to destroy rocks every tick.
• Trisagion: Overridden by Brimstone.

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.
  • Ironically enough, prior to update V1.7.5, Brimstone was changed such that it didn't contribute to the Leviathan transformation.
• Brimstone has the same appearance of The Pact, but with big, curved horns and slightly less angry eyes.
• 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.
• Brimstone is one of the few items that will give Isaac a unique costume when two copies are acquired, along with Guppy's Eye and Glass Eye.
• 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.

Bugs

Bug!	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!	When having Brimstone + My Reflection and facing towards an east/west 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.

Bug!	PC Brimstone will occasionally fire the laser to the right, regardless of the direction chosen.
