The Iron Butcher is the first optional fight on the Mountain of Imprisonment and the source of the temper that makes Jagged Steel’s Bleed pass through block. The fight is a heavy-axe exchange: sidestep the swing, punish the downswing, and do not try to out-trade the recovery.
Location and unlock
The Iron Butcher is an optional boss in the Mountain of Imprisonment, Chapter 6, fought at The Lady’s Path. He is the first optional encounter in the region, found at Iron Butcher’s Camp on the path after you ring the entry bell. The Mountain route places him at step 2, before Commander’s Platform, Kui Yanyan, Jade-Face, and Huangxing.
There is no unlock condition beyond reaching the Mountain. The region itself is optional for a Normal-ending run but required for the true-ending chain, and the Butcher is one of its five optional fights.
Reward and missable warning
The drop is the Iron Butcher Mask. Its importance is easy to undersell: it is the temper material for Jagged Steel, adding Open Wounds so Bleed applies through block. The site’s best-builds guide calls this the removal of the only counter to the Bleed build.
The Butcher is optional, and missed optional bosses remain available in post-story free roam. The practical deadline is the Green Serpent House door in Pangzhen: the Mountain’s shrine objectives are cut off when you open the Mirage passage. If you use Jagged Steel, take the mask before you leave. Boss drops are one-per-run.
Fight plan: sidestep the axe, punish the downswing
The boss table’s line is “sidestep axe; punish downswing.” The fight is a heavy-weapon exchange.
Sidestep the axe. The Butcher’s swings are committed and wide. A lateral step takes you off the impact line and keeps you close enough to punish. Backing up keeps you on the line and may put you against the camp geometry.
Punish the downswing. The overhead/downswing recovery is the clean window. Wait for the axe to commit, step off the line, and take a short combo after the impact. Do not punish the wind-up; the axe is still coming down.
Reset. One combo, then move. The next swing is already being set up, and greed is how the recovery turns into a trade.
No HP value, phase count, or named moveset is published. Treat the fight as a single-phase heavy-swing check.
Attack tells
No full colour map or named moveset is published. The documented tells are the axe swing and the downswing; the rest is universal grammar.
| Tell | Response | Punish |
|---|---|---|
| Wide axe swing | Sidestep laterally | Re-enter after the swing |
| Downswing | Step off the line | Punish the recovery |
| Blue-flash hit | Parry | Short counter |
| Red-flash hit | Dodge | Do not block or parry |
If the axe glows red, do not try to parry the downswing; dodge the commitment. The normal swing can be guarded or parried, but the recovery is the reliable damage.
Recommended weapon and build
Bring a mobile main with a short combo. The Butcher’s windows are short and the axe covers a lot of space, so a weapon that commits to a long animation will eat the next swing. A guard-break option is useful but not required.
If you are a Jagged Steel user, this is a priority kill: the mask’s Open Wounds temper is the build’s answer to blocking enemies. The best builds guide covers the Bleed setup, and the Mountain of Imprisonment walkthrough places the camp on the route.
Common mistakes
- Backpedalling the axe. Sidestep laterally.
- Punishing the wind-up. Wait for the downswing recovery.
- Greeding for a second combo. One combo, then reset.
- Skipping the mask. It is the Jagged Steel Bleed-through-block temper.
- Leaving the Mountain before the shrine objectives. The Green Serpent House door is the cutoff.
- Forgetting the Banyan duo. The Butcher returns alongside Jagged Steel at the Shrine Outer Gate Banyan; keep both in frame.
Sources & confidence
The Lady’s Path location, optional status, Iron Butcher Mask reward, sidestep instruction, and downswing punish come from the boss table and the Mountain of Imprisonment route, which draw on PowerPyx’s played walkthrough and KeenGamer’s boss list. The mask’s Open Wounds temper and its role in the Jagged Steel build come from the best-builds and all-weapons tables. No HP value or named moveset is published, so the guide stays with the documented axe exchange.
