Brimstone

Brimstone is a special passive item.

Effects

 * Tears are replaced by a charged blood laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.

Interactions

 * 20/20: Overridden by Brimstone.
 * Shoots two Brimstone lasers simultaneously without increasing charge time.
 * 8 Inch Nails: Brimstone pushes enemies away in the direction the beam is travelling, but not out of the path of the beam.
 * A Lump of Coal: Changes the color, but does not have an effect on damage.
 * Beam will gradually increase in size but rapidly increase damage the farther it travels, on a multiplier that is roughly +20% per tile of distance. This allows for a huge damage increase from longer distances.
 * Chocolate Milk: Decreases charge time slightly, but does not increase damage.
 * Continuum: Overridden by Brimstone.
 * Cursed Eye: Brimstone overrides the burst shot effect but damage is increased. Charge time decreased.
 * Dr. Fetus: Overrides Brimstone.
 * Isaac shoots bombs while charging Brimstone.
 * Epic Fetus: Overrides Brimstone.
 * 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.
 * Evil Eye: Overridden by Brimstone.
 * Fire Mind: Beam inflicts burning, but cannot cause explosions or leave fires on the ground.
 * Flat Worm: No effect.
 * Holy Light: Overridden by Brimstone.
 * Hook Worm: Beam changes angles while firing straight, but also effectively increases the width of the beam.
 * Ipecac: The character gains neither the increased damage nor the decreased tears of Ipecac. They only gain the minor poison effect.
 * Isaac shoots Ipecac tears while charging Brimstone. Isaac gains increased damage, decreased tears, and the poison effect.
 * Isaac's Tears: Fires normal tears, but nearly instantly charges when charging Brimstone.
 * Jacob's Ladder: Overridden by Brimstone.
 * Monstro's Lung: Overridden by Brimstone.
 * Fires multiple 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: Overridden by Brimstone.
 * Makes the beam curve when moving. Has the same effect on Azazel's mini-brimstone but doubles the range.
 * Mysterious Liquid: Overridden by Brimstone.
 * When Brimstone hits enemies or walls it leaves creep based on how long it hits.
 * Ouija Board: Overridden by Brimstone.
 * Pupula Duplex: Overridden by Brimstone.
 * Rubber Cement: Lasers ricochet off walls.
 * Soy Milk: Greatly reduces Brimstone charge time and damage.
 * Technology: Overridden by Brimstone.
 * Brimstone beams become surrounded with swiveling Technology laser beams, granting a 1.5x damage multiplier.
 * Technology 2: Laser fires while Brimstone is charging.
 * The Parasite: Overridden by Brimstone.
 * Wiggle Worm: Makes the beam wavy.

Synergies

 * 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. 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
 * Incubus won't fire delayed Brimstone shots and will fire regular Brimstone shots instead.
 * Dark Matter: Beam will have a chance to cause fear.
 * Diplopia: Picking up two Brimstones will make Isaac simultaneously fire two lasers, similar to the 20/20 effect.
 * God's Flesh: Chance to shrink enemies and turns the beam indigo.
 * 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.
 * Loki's Horns: Occasionally causes Isaac to fire the beam in all four cardinal directions, similarly to Head of Krampus's effect.
 * The Ludovico Technique: Laser is now a controllable circular beam. Enemies directly inside the circle won't be hurt.
 * The Mulligan: Spawns blue flies constantly when hitting an enemy.
 * Mom's Eye: Sometimes shoots a laser from the back of Isaac's head.
 * Mom's Knife: Adds a small barrage of knives after the main knife is fired. The barrage of knives goes all the way across the screen and increases in quantity the longer the charge.
 * 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.
 * Monstro's Lung - Causes Isaac to fire multiple beams in random directions.
 * Mutant Spider: Increases charge time but fires four separate Brimstone beams instead of one. Azazel's beams overlay each other instead of spreading out, causing additional damage.
 * Number One: Greatly decreases charge time and turns beam yellow.
 * Polyphemus: Significantly increases damage and increases charge duration.
 * Proptosis: Damage is doubled with no drop-off at range.
 * Range is unchanged, but damage quickly drops further along the beam. This also affects the beams produced by Tammy's Head.
 * Sacred Heart: Increases damage and makes laser home in on enemies.
 * Sad Bombs: 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: Slow effect persists and turns the beam color to light pink.
 * Spoon Bender: Turns beam purple and makes it curve towards enemies similar to The Gate's. Azazel's mini-brimstone charge will become purple, but will not home.
 * Strange Attractor: Enemies are sucked towards the beam, increasing damage significantly. Consumables will also be moved by the beam.
 * Tammy's Head: Fires Brimstone beams in every direction.
 * Tech X: Brimstone now becomes a large ring that varies in size depending on how long it is charged before firing.
 * Tech X + A Lump of Coal: The Brimstone ring now increases in size and damage the further it travels.
 * Tech X + Mom's Knife: Mom's Knife and a Mom's Knife+Brimstone barrage are shot alongside the rings.
 * The Common Cold: Beam turns green and poisons enemies.
 * The Inner Eye: Produces 3 beams and greatly increases charge time.
 * Tiny Planet: The beam will wrap around the character and shoot straight forward.

Trivia

 * The term brimstone (burn stone) comes from the King James Bible in reference to burning sulfur.
 * 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
