The Brimstone Elemental is a Hardmode boss fought in the Brimstone Crag biome. She cycles through three distinct behaviors, with varying levels of aggression and methods of attack.

After Providence, the Profaned Goddess has been defeated, she becomes much stronger and begins dropping Bloodstone, which can be combined with Phantoplasm and Blood Orbs to make Bloodstone Cores.


The Brimstone Elemental does not spawn on her own and requires the player to summon her with the Charred Idol. She must be summoned in the Brimstone Crag.

The Brimstone Elemental has 3 phases, starting out in phase 1, and randomly cycling through them after fully completing the attack. She cannot repeat the same phase twice in a row. Phase 3 can only be entered after she attacks 3 times.

Leaving the Brimstone Crag or The Underworld layer will cause the Brimstone Elemental to enrage, increasing her movement speed, projectile speed, and fire rate in all three phases. The enrage is even more effective if both conditions are met.


Phase 1[]

  • She slowly moves towards the player.
  • After 5.13 / 4.63 seconds, she will teleport to somewhere randomly near the player.
    • The location she teleports to is telegraph by a zone of red dust 2.13 seconds before occurring.
    • She performs the teleport twice before changing to another phase.

Phase 2[]

  • She accelerates towards the player and attempts to stay slightly above.
  • She fires Brimstone HellfireballBrimstone Hellfireballs with high acceleration towards the player every 0.83 / 0.67-0.83 / 0.58-0.75 / 0.5-0.67 seconds.
    • After 4 seconds or upon collision with solid tiles, Brimstone Hellfireballs leave behind a damaging stationary explosion that lasts 3 seconds.
  • For every two fireballs fired, she also fires a spread of four slower BrimstoneBarrageBrimstone Darts.
  • She changes to another phase after firing 10 Brimstone Hellfireballs.

Phase 3[]

  • She decelerates to a stop and closes her petals, increasing her defense to 99,999 and completely reduces the effectiveness of most homing attacks.
  • Every 2 / 1-2 seconds, she fires an evenly-spaced ring of 12 / 16 BrimstoneBarrageBrimstone Darts along with a fast, arc-shaped barrage of 6 BrimstoneHellblastBrimstone Hellblasts.
  • She changes to another phase after 5 / 4 seconds.

In Expert Mode[]

  • Moves faster in her first phase, even faster as her health lowers.
  • In phase 2 and 3, she fires projectiles at a faster rate as her health lowers.
  • Brimstone Hellfireballs travel at a faster speed as her health lowers.

In Revengeance Mode[]

  • After every teleport, she summons a Brimling to aid her during the fight.
    • She will stop spawning Brimlings once there are two present.
  • Increased base movement speed in phase 1, firing rate in phase 2, and projectile speed of Brimstone Hellfireballs.
  • When below 50% health, she will only teleport once during phase 1.
  • The Brimstone Elemental gains a new phase below 50% health which can appear in her randomized pool:
    • During the phase, her defense is tripled.
    • Her movement behaves identically to phase 1, but decelerates once a Brimstone Ray is fired.
    • She attempts to aim ahead of the player with a line telegraph for 1.67 seconds. After, the line locks onto the position it last tracked and stays there for 0.33 seconds. These times are reduced to 1.25 seconds and 0.25 seconds respectively for her second shot.
    • Then, a Brimstone Ray appear at the line's position, remaining still for 0.75 seconds, then bursts into an two rows of evenly-spaced Brimstone Darts, which travel perpendicularly out of the ray.
    • After one second, she fires a second ray, or cycles into her next phase once both rays have been fired.
  • Once she drops below 33% health, she will no longer be able to cycle to her first phase.

In Death Mode[]

  • Decreased teleport delay and increased movement speed in phase 1, even higher as her health decreases.
  • Increased movement speed, projectile speed, and firing rate in phase 2. Fires 8 Brimstone Darts per spread instead of 4.
  • Increased projectile speed in phase 3, in addition to firing a second ring of Brimstone Darts. Transitions into the next phase after 4 seconds instead of 5.
  • Fires only one Brimstone Ray with greater movement responsiveness. Darts from the Brimstone Ray are slower, but now home in on the player.

During the Boss Rush[]

  • Does not have an enrage state.
  • Teleport delay decreased from 5.13 / 4.63 to 3.63 seconds.
  • Greatly increased movement speed in phases 1 and 2, and projectile speed in phases 2 and 3.
  • Decreased firing delay in phase 3 from 2 / 1-2 seconds to 0.67 / 0.5-0.67 seconds.

For more elaborate strategies on defeating the Brimstone Elemental, including weapon and arena recommendations, see Guide:Brimstone Elemental strategies.
  • Try mining out the Brimstone Slag. This will offer more mobility to dodge her attacks.
    • Alternatively, one could use explosives like Bombs and Dynamite to destroy the slag and make a large, clear area.
  • The Brimstone Crag has very rough terrain that's easy to get stuck on, so it's a good idea to smooth out the walls, roof and ground of the arena.
  • Try to move around and focus on dodging instead of attacking when she closes her petals, as her projectiles can travel through blocks and her defense is greatly increased in this phase.
    • The player should be aware of their proximity to her during this phase, as the further they are from her, the faster her projectiles go.
    • If the player is too close however, her projectiles will have no time to spread out, so dodging them may be harder.
  • If the player has the Early Hardmode Progression Rework enabled in the configuration options, she can only be fought once two mechanical bosses are defeated, as crafting her summon requires a Hardmode Forge.
    • However, if the rework is turned off, she can be fought at the start of Hardmode.


  • The Brimstone Elemental's theme is Left Alone, which was composed by the artist DM DOKURO.
    • If the Calamity Music add-on mod is disabled, Boss 4 will play instead.
  • While some artwork depicts her as having two eyes, the Brimstone Elemental is actually a cyclops. This could be because her phase one sprite's pupil stretches the height of her eye, "splitting" it into two.
  • The projectiles used in her brimstone barrages are the same projectiles used in the Supreme Calamitas fight.
  • The Brimstone Elemental can be fought at the start of Hardmode, as her summoning item only requires Souls of Night, Essences of Chaos, and Unholy Cores.
    • However, if the Rework Early Hardmode Progression configuration option is enabled, she can be fought after any Mechanical Boss is defeated.
  • The Brimstone Elemental was previously an alternative for Skeletron Prime because of her previous ability to drop Souls of Fright.
  • The Brimstone Elemental was formerly referred to as "BrimstoneWaifu" in the mod's files.
  • If the Boss Checklist Mod is installed, her unique despawn message will be "Brimstone Elemental withdraws to the ruins of her shrine."


As the world took shape long ago, the planet's will adopted a physical form - born from the elements as they formed, becoming five as they distinguished themselves from one another. When the first of humanity discovered these creatures, they were awed by their beauty and magic. The humans worshiped the Elementals - their faith and love empowering them into nigh-goddesses. They enjoyed their newfound strength and followers for thousands of years...but as humans grew aware of and understood the world around them, they also grew disillusioned with their idols. Their religions and power dwindled over the course of centuries; the gift of magic was taken and harnessed by humans, further undermining the Elementals.

The sprite born of the Underworld's flames was the first and the strongest of the five "sisters" - the last to retain her following while the others quietly returned to the aspects of the world that gave rise to them. It wasn't meant to last; a human entered the Underworld one day, abyssal flames burning in her wake as she wielded catastrophic magic that put all of Hell itself to shame. Dispatched under the Jungle Tyrant's command, Calamitas laid waste to the civilization at the core of the planet and reduced it to smoldering rubble in a single night. What had once been the capital of the Underworld was left a foul blackened monument whose unholy energy cursed all who set foot upon it.

That Elemental was no match for Calamitas. Barely clinging to life after the witch tired of her massacre and vanished, what had once been a goddess in all but name was reduced to a mere beast fighting for survival within the twisted ruins of the capital - kept alive by little more than her natural affinity with the chaotic magic that lingered within the crags. Her few remaining followers lost in a human's seemingly pointless slaughter, the Brimstone Elemental swore that humanity would be her enemy until the end of time; any attempt to worship her doubtless a mockery for which she would use all her power to kill the perpetrator, no matter how pitiable a shadow she was of her former self.
