"A peculiar being. ...she had laid dormant for ages, posing as [Azafure]'s silent matron."

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.

Spawn

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.

Behavior

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.

Attacks

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 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 Brimstone 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 reducing the effectiveness of most homing attacks.
Every 2 / 1-2 seconds, she fires an evenly-spaced ring of 12 / 16 Brimstone Darts along with a fast, arc-shaped barrage of 6 Brimstone 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

Brimstone Ray now splits into Brimstone Darts that can home into the player.
The number of Brimstone Darts from a ring during the cocoon phase is reduced from 16 to 12, but 2 rings are fired at a time instead of 1.
Doubled the amount of Brimstone Darts fired in a spread but halved the attack rate and the amount of Hellfireballs fired to transition to the next phase.
Number of Brimlings reduced to 1.
Brimlings shoot Hellfireballs twice as fast.
Reduced the time taken to teleport from 4.63 seconds to 2.63 seconds.
Reappears 50% faster after a teleport.

On the For the worthy seed

Only teleports once before transitioning to her next phase.
Fires triple the amount of Brimstone Darts during phase 2 and in a larger spread.
Fires barrages of projectiles 2 times per second in phase 3.
Shoots two laser beams at once, with the second one going in the opposite direction of the first.
Brimstone Darts and Hellblasts now inflict Vulnerability Hex for 2 seconds each.

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.

Brimstone Crates now have a chance of containing Unholy Cores.

Tips

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.
Fighting her on the bridge in the center of the biome is a good idea, as it offers a large amount of clear space.
- Put blocks or platforms in the holes on the bridge to prevent falling through them. Additionally, adding a platform spanning the bridge above it may also help with avoiding the boss and her projectiles.
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 one of the mechanical bosses is defeated, as the Infernal Suevite needed to craft her summon requires at least a Mythril Pickaxe to mine.
- However, if the rework is turned off, she can be fought at the start of Hardmode.

Trivia

The Bestiary entry for the Brimstone Elemental: "Roused from her deep slumber in relatively recent years, her awakening set into motion the downfall of Azafure. Most blame her unexpected revival on the city’s overzealous mining of Brimstone, while a few blame the city’s pollution, and some fewer cite dubious prophecies. But behind closed doors, there are whisperings that she was revived deliberately as part of a plot by opposing forces."

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 cycloptic. This could be because her phase one sprite's pupil stretches the height of her eye, "splitting" it into two.
The Brimstone Elemental's laser telegraph is based on Badeline's laser from the game Celeste, and the resulting Brimstone Barrage projectiles are based on an attack from Noita.
The projectiles used in her brimstone barrages are the same projectiles used in the Supreme Witch, Calamitas fight.
The Brimstone Elemental can be fought at the start of Hardmode, as her summoning item only requires Souls of Night, Essences of Havoc, 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 formerly referred to as "BrimstoneWaifu" in the mod's files.
The Brimstone Elemental is the only boss that deals contact damage which doesn't deal defense damage on contact.
If the Boss Checklist Mod is installed, her unique despawn message will be "The elemental ever maintains her somber vigil over Azafure…"
