Brimstone Witch
The Brimstone Witch line is the longest storyline in the Calamity Overhaul adventure. A short while after you defeat the Calamitas Clone, she steps in with her own portrait and tells you she has only come to “measure” you. This first meeting offers two answers, fight or silence. Only drawing a weapon opens the rest of the story.
Choosing to fight carries the arc forward into the Moon Lord chapter, then into three commissions where she hands you a weapon and asks you to hunt a specific boss with it. Partway through, Halibut steps in to talk you out of working for the witch. Once all three commissions are turned in, the Brimstone Witch fight swaps to a full set of story lines and leads into the bad ending, Eternal Blazing Now, shortened to EBN on this page.

Dialogue and commission panels use the brimstone-fire presentation style.
Flow overview
Section titled “Flow overview”First meeting
Section titled “First meeting”| Your choice | Outcome |
|---|---|
| Draw weapon | Summons the Brimstone Witch; win or lose before Moon Lord each has an ending, and it can be retried |
| Stay silent | She leaves 999 Ashes of Calamity and departs; the hunt chain does not begin |
Main route (requires drawing a weapon at the first meeting)
Section titled “Main route (requires drawing a weapon at the first meeting)”| Step | Event |
|---|---|
| 1 | Defeat Moon Lord → post-fight scene → receive the Pallbearer; Commission ① registers |
| 2 | Commission ①: kill Providence with 80% Pallbearer contribution → Heartcarver + Commission ② |
| 3 | During Commission ②: Halibut steps in |
| 4 | Commission ②: kill the Devourer of Gods with 80% Heartcarver contribution → Oni Machete + Commission ③ |
| 5 | Commission ③: kill Yharon with 75% Oni Machete contribution → Auric Bars + Proverb |
| 6 | Defeat all four Exo Mechs → rewritten fight lines → EBN ending |
Notes:
- If the world already records the Brimstone Witch as defeated, the first meeting no longer triggers.
- While holding the legendary Halibut, claim the matching boss gift first so nothing clashes with the first meeting or the Moon Lord scene.
- The Moon Lord reward and all three commissions require choosing draw weapon at the first meeting.
- In the commission tracker, these three jobs are filed under the Brimstone Witch category.

Other beats
Section titled “Other beats”| Situation | Notes |
|---|---|
| First fight lost | Repeatable; valid before Moon Lord |
| First fight won before Moon Lord | The witch reels, curses, and flees; you get Ashes of Calamity ×999 |
| Legendary Halibut easter egg | Beat the Brimstone Witch while holding the legendary Halibut with the sea domain at layer 10 or above; Halibut and the witch trade extra barbs (no effect on the commissions) |
| Altar gate | With Commission ③ done but the Exo Mechs not yet all defeated, the altar summons nothing |
| Rewritten fight lines | After the commission chain, the Brimstone Witch fight uses story dialogue |
| After EBN | For a player who reached EBN, summoning the Brimstone Witch teleports them to the boss position and the witch NPC no longer appears; her post-fight portrait removes the hood |
