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.
      • (except in Repentance) Brimstone ticks 13 times over the course of 0.9 seconds (54 frames).
      • (in Repentance) Brimstone ticks 9 times in ~0.63 seconds (38 frames).
    • (in Repentance) 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.
  • Tears down: (except in Repentance) Tear Delay × 3 / (in Repentance) Fire Rate ÷ 3.
  • (except in Rebirth) This item belongs to the LeviathanLeviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes[ | ]

  • (except in Repentance) Brimstone is a special item.
  • Character Azazel iconAzazel 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.
    • (except in Rebirth) His Brimstone's shorter range can be increased with range up items or pills.
  • Multi-shot effects like Collectible 20 20 icon20/20 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.
  • (in Repentance) Character Tainted Azazel iconTainted Azazel has a full range, but thinner beam whose damage is halved unless enemies are cursed by his inherent Collectible Hemoptysis iconHemoptysis sneeze.
  • The beam will apply Tear effects and does so frequently thanks to its high tick rate.
  • Any item that grants homing tears: will cause the beam to make sharp turns and even loops to hit enemies, which is extremely powerful. Character Azazel iconAzazel's mini-brimstone does not home unless he has a high range stat.

Synergies[ | ]

  • (except in Rebirth)Collectible 20 20 icon20/20: Adds a second Brimstone.
  • (in Repentance)Collectible Almond Milk iconAlmond 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
  • Character Azazel iconAzazel / (in Repentance) Character Tainted Azazel iconTainted Azazel: Picking up Brimstone with him will give him the regular version.
  • (in Afterbirth †)Collectible Apple! iconApple! / (in Afterbirth †)Collectible Euthanasia iconEuthanasia / (except in Repentance)Collectible Tough Love iconTough 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.
    • (in Repentance) The bonus applies randomly on every tick of the beam, including the insta-kill ability from Euthanasia.
  • Collectible Anti-Gravity iconAnti-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 Character Azazel iconAzazel as the beam does not increase in range. (in Repentance) Size and damage of the beams no longer scale with fire rate nor lasts infinitely at above 15 fire rate.
    • (in Repentance) Anti-Gravity + Collectible Soy Milk iconSoy Milk / Collectible Almond Milk iconAlmond Milk: Allows auto firing upon full charge but without permanent beam uptime.
    • (in Afterbirth and Afterbirth †) Anti-Gravity + Collectible Incubus iconIncubus: Isaac will fire Brimstone orbs, while Incubus will fire regular Brimstone beams.
      • (in Repentance) Both Isaac and Incubus fire Brimstone orbs.
  • (in Repentance)Brain WormBrain 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:
    • (except in Repentance) Additional copies of this item, such as from (except in Rebirth)Collectible Diplopia iconDiplopia / (in Afterbirth † and Repentance)Collectible Crooked Penny iconCrooked Penny adds another beam, with no increase in charge time.
    • (in Repentance) 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 Character Azazel iconAzazel's Collectible Birthright iconBirthright effect, the laser beam will be 4x wider.
      • The bigger beam granted by double Brimstone synergizes with other items as expected.
  • (in Repentance)Collectible Chocolate Milk iconChocolate 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.
  • (in Repentance)Collectible Continuum iconContinuum: Brimstone laser travels through the wall and appears out the other side once.
  • (in Repentance)Collectible Cricket's Body iconCricket's Body: Spawns split tears on the first enemy or obstacle the beam hits.
  • (in Repentance)Collectible C Section iconC Section: Shoots 4 fetus tears along with the brimstone beam.
  • (except in Rebirth)Collectible Dead Eye iconDead Eye: The damage multiplier that was gained before picking up Brimstone will now be permanent. However, saving and quitting the run will result in this damage multiplier being permanently lost (which is a bug).
  • (in Repentance)Collectible Dataminer iconDataminer: Dataminer can be used to underflow Isaac's tears to immediately bring it to 120, maxing out Brimstone's width and damage via tears.
  • (except in Rebirth)Collectible Epic Fetus iconEpic Fetus: Adds a Brimstone Sad Bombs effect: missile explosions shoot ten beams in all directions, massively increasing damage and area of effect.
  • (in Repentance)Collectible Explosivo iconExplosivo / Collectible Sinus Infection iconSinus Infection: The beam has chance to stick tears to enemies on every other tick.
  • (in Repentance)Collectible Eye of the Occult iconEye of the Occult: Creates a controllable crosshair similar to Collectible Marked iconMarked. Fires automatically upon reaching full charge. The beam curves towards the crosshair and then attempts to hit the wall Isaac is facing.
    • Brimstone + Collectible Tech.5 iconTech.5 / Collectible Technology 2 iconTechnology 2: Tech.5 and Technology 2 lasers are also affected by the crosshair but cannot create the crosshair on their own.
  • GuppyGuppy: Blue Flies are spawned at a rate of approximately one blue fly per tick ((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.
  • (in Afterbirth † and Repentance)Collectible Haemolacria iconHaemolacria: +20 Tear Delay after Haemolacria's tears down. Tears burst into 4-7 Brimstone beams that do Isaac's damage per tick.
    • Character Azazel iconAzazel / (in Repentance) Character Tainted Azazel iconTainted Azazel: Overrides these characters' Brimstone. Tears do not burst into Brimstone beams.
    • (in Repentance) Double Brimstone: Grants +1 Damage but not the 1.2x damage multiplier. The width of the beams doubles.
    • Haemolacria + Collectible Chocolate Milk iconChocolate Milk: The Brimstone beams deal full damage regardless of charge.
    • (in Repentance) Haemolacria + Collectible Technology iconTechnology: The lasers coil the beams. This is purely visual and does not grant a 1.5x damage multiplier.
  • (in Repentance)Collectible Head of the Keeper iconHead of the Keeper: Makes the laser yellow and upon a tick has a chance to drop a coin.
  • (in Repentance)Collectible Hemoptysis iconHemoptysis: Enemies hit by the sneeze will gain a curse that increases the damage Brimstone deals to 2x and +3 flat damage. Enemies who die to Brimstone under the curse will damage and spread the curse to nearby enemies.
  • (in Repentance)Collectible Holy Light iconHoly Light: Every tick of the beam has a chance of summoning a beam of light.
  • Hook WormHook Worm: Beam shifts left to right while firing straight and forms angles that constantly flatten and expand, effectively increasing its width.
  • (in Repentance)Collectible Jacob's Ladder iconJacob's Ladder: Upon hitting an enemy, wall or obstacle, the beam generates sparks that home in on enemies.
  • (in Repentance)Collectible Lead Pencil iconLead Pencil: Lead Pencil triggers approximately every 2 seconds as the beam is fired (charge time is not counted).
  • Collectible Loki's Horns iconLoki's Horns: Adds a chance to shoot a beam from all four cardinal directions, similarly to Collectible Head of Krampus iconHead of Krampus's effect.
  • Collectible The Ludovico Technique iconThe 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 + (in Repentance)Collectible C Section iconC Section: Disables C Section. Fetuses no longer spawn.
    • The Ludovico Technique + (except in Rebirth)Collectible Incubus iconIncubus:
      • (except in Repentance) Incubus' Brimstone laser is not affected by Ludovico Technique.
      • (in Repentance) Adds a smaller controllable laser ring in addition to the main one.
    • The Ludovico Technique + Collectible A Lump of Coal iconA Lump of Coal: The ring increases in diameter when Isaac is further; 100% when he is on the center, 1.25x when he is 12.5 tiles of distance away.
      • (except in Repentance) The damage increases on distance but is reduced while Isaac is in the ring.
      • (in Repentance) The damage increase 20% per tile of distance.
    • The Ludovico Technique + Collectible Mom's Knife iconMom's Knife: Overrides Brimstone.
    • The Ludovico Technique + Collectible Proptosis iconProptosis: The ring deals 1.5x Isaac's Damage at its largest, and 50% at its smallest. 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.
  • (except in Rebirth)Collectible A Lump of Coal iconA 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.
  • (in Repentance)Collectible Marked iconMarked: Fires automatically upon reaching full charge. Fires at the direction of the crosshair.
  • Collectible Mom's Eye iconMom's Eye: Adds a chance to shoot a beam from the back of Isaac's head.
  • Collectible Mom's Knife iconMom'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 (except in Repentance) 80% of / (in Repentance) 2x Isaac's tear damage.
    • 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%.
    • This effect does not work with Character Azazel iconAzazel or Character Tainted Azazel iconTainted Azazel's versions of Brimstone.
  • (in Rebirth and Afterbirth)Collectible Mom's Wig iconMom'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.
    • (in Afterbirth † and Repentance) The blue spiders only spawn while the beam is firing.
  • (except in Rebirth)Collectible Monstro's Lung iconMonstro's Lung: 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 Character Azazel iconAzazel and (in Repentance) Character Tainted Azazel iconTainted Azazel's Brimstone.
    • (except in Repentance) Charging a new Brimstone beam removes the original from in front of Isaac, but not the additional ones added by Monstro's Lung.
  • (except in Rebirth)Collectible Multidimensional Baby iconMultidimensional Baby: If a brimstone laser is shot through the baby, it will double the laser.
  • (in Afterbirth and Afterbirth †)Collectible My Reflection iconMy Reflection: Makes the beam curve when moving. It has the same effect on Character Azazel iconAzazel's mini-brimstone but doubles the range.
    • (in Repentance) Makes the beam shoot from the back. An oval beam is shot from the front instead.
  • (in Repentance)Collectible Mucormycosis iconMucormycosis: The beam has 25% chance to spawn spore to enemies on every other tick.
  • (except in Rebirth)Collectible Mysterious Liquid iconMysterious Liquid: Leaves a creep for each enemy and obstacle the beam hits, on every other tick. Character Azazel iconAzazel's Brimstone leaves creeps at the end of its range.
  • (in Repentance)Collectible Ocular Rift iconOcular Rift: Rifts may appear where the beam hits rocks, walls or enemies.
  • (in Repentance)Ouroboros WormOuroboros Worm: The beam will make large loops on itself. The homing is present, but unreliable.
  • (in Repentance)Collectible The Parasite iconThe Parasite: Spawns two perpendicular beams on the first enemy or obstacle the beam hits.
  • (in Repentance)Collectible Rotten Tomato iconRotten Tomato: Each tick of the beam's damage can mark enemies.
  • (except in Rebirth)Collectible Rubber Cement iconRubber Cement: Beams bounce off of walls once, creating a second beam that deals (except in Repentance) half / (in Repentance) full damage.
    • (in Afterbirth) If Character Azazel iconAzazel's mini Brimstone beam bounces off a wall, it effectively becomes a full-length Brimstone beam, but it will still only deal half damage.
      • (in Afterbirth † and Repentance) Character Azazel iconAzazel's Brimstone no longer becomes a full length beam after bouncing, instead bouncing as a regular mini-Brimstone.
    • Collectible Soy Milk iconSoy Milk: The Brimstone beam bounces off the wall at a perpendicular angle to where the beam was fired.
  • Collectible Sad Bombs iconSad Bombs: Upon exploding, bombs release ten beams in all directions.
    • (in Repentance) Brimstone does not benefit from Sad Bombs' flat damage bonus.
  • (in Repentance)Collectible Soy Milk iconSoy 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
    • (in Repentance)Collectible Soy Milk iconSoy Milk + Collectible Chocolate Milk iconChocolate Milk: The beam does 25% more damage. Does not increase Isaac's damage stat itself.
  • Collectible Strange Attractor iconStrange Attractor: Enemies are attracted towards the beam, improving its consistency. Consumables will also be moved by the beam.
  • (in Repentance)Collectible Sulfur iconSulfur: Grants a larger beam with a 1.2x damage multiplier and +1 damage (same effect as picking up a second Brimstone).
  • (in Repentance)Collectible Sulfuric Acid iconSulfuric Acid / Collectible Terra iconTerra: The beam has a chance to destroy rocks every tick. The laser will not destroy sealed doors or open secret rooms.
  • Collectible Tammy's Head iconTammy's Head: Shoots ten beams in all directions. Given the item's single room charge, this makes for an extremely powerful synergy.
    • (in Repentance) Brimstone does not benefit from Tammy's Head's flat damage bonus.
  • (except in Rebirth)Collectible Tech.5 iconTech.5: Tech.5 fires normally while charging Brimstone.
  • (except in Rebirth)Collectible Technology iconTechnology: The Technology laser coils around the Brimstone beam, granting a 1.5x damage multiplier (it stacks with other similar multipliers like Collectible Cricket's Head iconCricket's Head or Collectible Magic Mushroom iconMagic Mushroom).
    • (in Repentance) Technology's damage multiplier will be overridden if Isaac has the powered up version (from picking up Brimstone twice or using Collectible Sulfur iconSulfur with Brimstone); this can decrease Isaac's damage.
  • (except in Rebirth)Collectible Technology 2 iconTechnology 2: Both fire normally; the Technology laser fires while charging Brimstone.
  • (except in Rebirth)Collectible Tech X iconTech 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.
    • (in Repentance) Double Brimstone: Further increases the width of the ring, and grants +1 Damage.
    • Tech X + Character Azazel iconAzazel:
      • (in Rebirth and Afterbirth) Overridden by Azazel's Brimstone.
      • (in Afterbirth †) Overrides Azazel's Brimstone. This works quite well with Azazel's good initial damage stat and also negates his initial range penalty.
      • (in Repentance) Applies 35% damage penalty and fires a Brimstone ring instead of Tech X ring. If combined with Brimstone, the damage penalty is negated.
    • Tech X + Homing Shots: The ring bends itself to hit enemies if they are nearby.
    • (except in Repentance) Tech X + Collectible Mom's Knife iconMom's Knife: Mom's Knife and a Mom's Knife + Brimstone barrage are shot alongside the rings.
    • (except in Repentance) Tech X + Collectible Technology iconTechnology: The 1.5x damage multiplier from Brimstone + Technology is lost, but the laser fires while charging the Brimstone ring.
      • (in Repentance) Fires a Brimstone ring coiled by a laser. The 1.5x damage multiplier from Brimstone + Technology is retained.
  • Collectible Tiny Planet iconTiny Planet: The beam will wrap around Isaac once and then shoot straight forward.
    • (in Repentance) Tiny Planet + Collectible My Reflection iconMy 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.
  • (in Repentance)Collectible Uranus iconUranus: The beam will freeze any enemies killed by it, so long as they are not immune to the freeze effect.
  • Wiggle WormWiggle Worm: Beam becomes wavy while firing straight, effectively increasing its width.

Interactions[ | ]

Overridden by Brimstone:

Only stat effects are applied; otherwise overridden by Brimstone:

Other interactions:

  • (except in Rebirth)Collectible 8 Inch Nails icon8 Inch Nails: Beams gain knockback, pushing enemies away in the direction they travel but not out of their path. This increases its consistency.
  • (in Repentance)Collectible Abyss iconAbyss: When Isaac uses Abyss to absorb Brimstone it turns into a larger gray locust but otherwise acts like normal locusts created by Abyss.
  • (in Repentance)Collectible Bird's Eye iconBird's Eye: Will occasionally spawn a fire when firing.
  • (except in Repentance)Collectible Chocolate Milk iconChocolate Milk: Reduces Isaac's tear delay by 20%. Does not increase damage.
  • (in Rebirth and Repentance)Collectible Dr. Fetus iconDr. Fetus: Overrides Brimstone.
    • (in Afterbirth and Afterbirth †) Isaac continuously fires bombs while charging the beam.
  • (in Rebirth)Collectible Epic Fetus iconEpic Fetus: Overrides Brimstone.
  • (except in Rebirth)Collectible Epiphora iconEpiphora: 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.
  • Collectible Fire Mind iconFire Mind: The beam will not cause explosions, but will still set enemies on fire.
  • (in Afterbirth † and Repentance) Character The Forgotten iconThe 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.
  • (in Afterbirth †)Collectible Ghost Pepper iconGhost Pepper: The flames can still shoot from Isaac while holding the fire button.
    • (in Repentance) Has a chance to shoot flames for every other tick while the beam is being fired.
  • Collectible Godhead iconGodhead: Homing and stat bonuses apply, but the beam does not have a damaging aura.
  • (in Rebirth and Afterbirth)Collectible Ipecac iconIpecac: Does not apply Ipecac's stat changes. The beam poisons enemies.
    • (in Afterbirth †) 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.
    • (in Repentance) Applies +2 flat damage, instead 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 Collectible Soy Milk iconSoy Milk / Collectible Almond Milk iconAlmond Milk. The beam and its explosions poison enemies. Collectible The Ladder iconThe Ladder, when placed, will trigger the Ipecac-Brimstone explosions. (possibly a bug)
      • Ipecac + Collectible Haemolacria iconHaemolacria: The flat damage bonus is +40 instead of +2. Tears will explode into multiple brimstone beams, each of which explodes and has a chance to hit Isaac.
  • (in Rebirth and Afterbirth)Collectible Isaac's Tears iconIsaac's Tears: Fires normal tears, but nearly instantly charges when charging Brimstone.
    • (in Afterbirth †) Fires normal tears. Charges at the same rate as Isaac's fire rate while charging Brimstone.
    • (in Repentance) Fires normal tears. Charges when firing Brimstone.
  • (in Repentance)Collectible Knockout Drops iconKnockout Drops: Gives the lasers high knockback.
  • (in Repentance)Collectible Lachryphagy iconLachryphagy: Brimstone's range is lowered, but Lachryphagy tears will form at the end of the beam, which can be fed.
  • (in Afterbirth † and Repentance)Collectible Large Zit iconLarge Zit: Creep shots will still be fired occasionally while holding the fire button.
  • (in Repentance)Collectible Lodestone iconLodestone: Changes the beam to gray, can still apply the magnetized effect. The beams are not attracted to enemies with the magnetized effect.
  • Collectible Number One iconNumber One: Although Number One is otherwise purely beneficial with standard Brimstone, Character Azazel iconAzazel's range is severely affected.
  • (in Repentance)Collectible Playdough Cookie iconPlaydough Cookie: Brimstone will start cycling through colors and applies the standard chance of tear-effect on hit, with the homing effect occurring intermittently.
  • (in Repentance)Collectible Pop! iconPop!: Brimstone has shorter range, a bit longer than Character Azazel iconAzazel's brimstone, and it is not affected from Range. The beam fires Pop! tears at the end, which are Piercing.
  • (in Rebirth)Collectible Proptosis iconProptosis: Does not apply distance penalty.
    • (in Afterbirth and Afterbirth †) 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.
    • (in Repentance) 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.
  • (in Repentance)Collectible Spirit Sword iconSpirit Sword: Overrides Brimstone.
  • (in Repentance) Character Tainted Samson iconTainted Samson: Greatly decreases attack speed for Samson's rage mode melee attack and replaces the thrown jawbone with a large laser sphere (similarly to Character The Forgotten iconThe Forgotten).

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 black 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.
    • (in Repentance) Ironically enough, prior to update V1.7.5, Brimstone was changed such that it didn't contribute to the LeviathanLeviathan transformation.
  • (except in Repentance) Brimstone has the same appearance of Collectible The Pact iconThe 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.
  • (in Repentance) Brimstone is one of the few items that will give Isaac a unique costume when two copies are acquired, along with (in Repentance)Collectible Guppy's Eye iconGuppy's Eye and (in Repentance)Collectible Glass Eye iconGlass 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 Bug! (except in Repentance) Picking up Brimstone before picking up Collectible Scorpio iconScorpio will not change the beam's color. Picking up Scorpio before Brimstone, however, will properly change it to green.
Bug Bug! (in Repentance) When having Brimstone + Collectible My Reflection iconMy 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 Bug! (in Repentance) PC Brimstone will occasionally fire the laser the opposite direction.
