Brimstone is a special passive item.


  • 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.

  • 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 ranged version, his mini-brimstone won't have enough length to use any homing items. Added in Afterbirth His mini-brimstone's range can be increased with range up items or pills.

  • Added in Afterbirth8 Inch Nails 8 Inch Nails8 Inch Nails Afterbirth icon.png+1.5 Damage Up. Replaces Isaac's tears with nails, which have increased knockback.: Brimstone pushes enemies away in the direction the beam is travelling, but not out of the path of the beam.
  • Chocolate Milk Chocolate MilkCollectible Chocolate Milk icon.pngGrants charged tears that deal greater damage when fully charged.: Doesn't increase damage, but reduces Isaac's tear delay by 20%. Beam is colored brown.
  • Added in Afterbirth †Compound Fracture Compound FractureCollectible Compound Fracture icon.pngIncreases range. Tears turn into bones, which shatter into 1-3 bone shards upon hitting an enemy or obstacle./Cricket's Body Cricket's BodyCollectible Cricket's Body icon.pngGrants -1 Tear Delay and reduces Range. When tears hit an object or deplete their range, they spawn 4 smaller tears, whose Range and Damage scale with Isaac's.: Overridden by Brimstone. Stat effects are still applied.
  • Added in AfterbirthContinuum ContinuumCollectible Continuum Afterbirth icon.png+2.25 Range Up. +1.5 Tear Height. Isaac's tears travel through walls and appear out of the opposite wall. Isaac's tears also travel over rocks and objects.: Overridden by Brimstone.

    • Added in Afterbirth Isaac shoots bombs while charging Brimstone.
  • Epic Fetus Epic FetusCollectible Epic Fetus icon.pngIsaac's tears are replaced with guided missiles, like those used by the Doctor's Remote.: Overrides Brimstone.
    • Added in Afterbirth After the missile hits the ground, it spawns 10 Brimstone beams similar to the effect given by Sad Bombs. Azazel's mini-brimstone does not give the Sad Bombs effect.
  • Added in AfterbirthEvil Eye Evil EyeCollectible Evil Eye Afterbirth icon.pngWhile firing tears, Isaac has a chance to fire an eye across the screen with a very slow shot speed, which will fire tears of its own in the same direction as Isaac. The eye will be destroyed if it comes into contact with an enemy or obstacle.: Overridden by Brimstone.
  • Fire Mind Fire MindCollectible Fire Mind icon.pngGrants flaming tears that deal burning damage over time. Tears have a chance to explode on impact with an enemy, which creates a fire at the location of the explosion.: Beam inflicts burning, but cannot cause explosions or leave fires on the ground.
  • Added in Afterbirth †Flat Stone Flat StoneCollectible Flat Stone icon.pngTears bounce off the floor. Tears that hit an enemy after bouncing deal splash damage to all nearby enemies for 25% of Isaac's tear damage.: Overridden by Brimstone.
  • Flat Worm Flat WormTrinket Flat Worm icon.pngIsaac's tears take on an oblong appearance. They also push enemies back.: No effect.

    • Added in Afterbirth † 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 significantly increased damage. The beam is colored yellowish green. Take care to pre-charge Brimstone so that the Ipecac shot is on cooldown as Isaac enters a room.
  • Isaac's Tears Isaac's TearsCollectible Isaac's Tears Rebirth icon.png6 roomsShoots 8 tears around Isaac, which retain the damage, shot speed, and special effects of his tears. Each tear shot by Isaac increases item charge by one.: Fires normal tears, but nearly instantly charges when charging Brimstone.

  • Added in AfterbirthMarked MarkedCollectible Marked icon.pngIsaac will now fire tears automatically directed at a red target on the ground which is controlled by the player. This allows for a full 360 degree tear firing radius. Can be overridden by other tear modifiers such as Mom's Knife or Brimstone.: Overridden by Brimstone.
  • Monstro's Lung Monstro's LungCollectible Monstro's Lung icon.pngIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.: Overridden by Brimstone.
    • Added in Afterbirth Fires 3-5 additional Brimstone lasers in random directions around Isaac. Does not increase charge time. Charging a new Brimstone laser removes the original from in front of the player, but not the additional ones added by Monstro's Lung. This effectively increases fire rate.
  • My Reflection My ReflectionCollectible My Reflection icon.pngGives Isaac's tears a boomerang effect, and increases range and shot speed.: Overridden by Brimstone.
    • Added in Afterbirth Makes the beam curve when moving. Has the same effect on Azazel's mini-brimstone but doubles the range.

    • Added in Afterbirth When Brimstone hits enemies or walls it leaves creep based on how long it hits.
  • The Parasite The ParasiteCollectible The Parasite icon.pngIsaac's tears split in two when they hit something.: Overridden by Brimstone.

  • Added in AfterbirthPupula Duplex Pupula DuplexCollectible Pupula Duplex icon.pngTransforms Isaac's tears into a wide arc shape which gives them a much larger hitbox. Gives Isaac spectral tears which allows them to travel through objects in the environment (i.e. rocks).: Overridden by Brimstone.
  • Rubber Cement Rubber CementCollectible Rubber Cement icon.pngTears bounce off walls, enemies, and environmental objects.: Lasers ricochet off walls.
    • If Azael's mini Brimstone beam ricochets, it effectively becomes a full-length Brimstone beam.
  • Soy Milk Soy MilkSoy Milk Icon.pngTears shrink and do much less damage, but fire in very rapid succession.: Greatly reduces Brimstone charge time and damage.
  • Technology TechnologyTechnology Icon.pngReplaces tears with a piercing laser with unlimited range.: Overridden by Brimstone.

If a needle kills an enemy, it bursts into more needles./Tough Love Tough LoveCollectible Tough Love Rebirth icon.pngAdds a chance to shoot a tooth instead of a tear, which deals greater damage than regular tears.: 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.
  • Anti-Gravity Anti-GravityCollectible Anti-Gravity icon.png-2 Tear Delay. Tears float in position until firing ceases, after which they will fly off in the direction they were shot in.: An orb of energy expands, then shrinks while firing the beam after a delay. The orb still hurts enemies if they touch it. Makes it harder to hit enemies with Azazel as the laser does not increase in range. Effectively allows a faster firing rate, since Isaac can start charging a new shot immediately after releasing the fire key without cancelling the first shot and is a great combo with soy milk

  • Guppy: Flies are spawned at a rate of approximately one fly per tick of damage for each enemy it hits. This causes a lot of flies to spawn very quickly. The spawned flies will also move to attack the targeted enemy immediately.
  • Added in Afterbirth †Haemolacria HaemolacriaCollectible Haemolacria icon.pngTears are now fired in an arc. Upon hitting the floor, an obstacle, or an enemy, they burst into many smaller tears in all directions.

The barrage of knives goes all the way across the screen and increases in quantity the longer the charge.
  • Mom's Wig Mom's WigCollectible Mom's Wig icon.pngAdds a chance to spawn blue spiders when firing tears. Restores 1 red heart.: 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.
  • Monstro's Lung Monstro's LungCollectible Monstro's Lung icon.pngIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.: Causes Isaac to fire multiple beams in random directions.
  • The Mulligan The MulliganCollectible The Mulligan Rebirth icon.pngTears have a 1/6 chance of spawning allied blue flies when they hit an enemy.: Spawns blue flies constantly when hitting an enemy.

  • Sad Bombs Sad BombsCollectible Sad Bombs Rebirth icon.png+5 Bombs. Upon exploding, bombs shoot 8 tears off in every direction, similar to Tammy's Head. The tears are affected by any tear modifiers Isaac has on his own tears.: Changes the tears fired by bombs upon their explosions to Brimstone beams, in a manner identical to its synergy with Tammy's Head.
  • Spider Bite Spider BiteSpider Bite Icon.pngAdds a chance to shoot slowing tears, reducing speed of enemy movement and any projectile fired by them.: Slow effect persists and turns the beam color to light pink.

In-game Footage


  • The term brimstone (burn stone) comes from the King James Bible in reference to burning sulfur. It is used in the phrase "fire and brimstone" to describe the torments of hell.
  • 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.
