Mistfall Hunter All Bosses: Complete Guide to Otto, General Harald, and the Mist Lord

I’ve put about 40 hours into Mistfall Hunter since launch week, and I’m not going to lie — the first time I walked into Otto the Flesheater’s room, I got folded in under 20 seconds. The extraction ARPG formula already punishes mistakes with your gear on the line, but the boss fights in this game add a whole different layer of tension. This guide covers every boss currently in the game across both maps, what they do at each HP threshold, and how I eventually learned to stop dying to them.

---

Map & Boss Overview

Mistfall Hunter currently has two main maps. Each map has two roaming bosses and a Mist Lord that spawns in a sealed arena. The bosses are not random — they appear in fixed locations every match, but whether another squad has already killed them or is waiting to ambush you while you fight is a different question.

Map	Roaming Bosses	Mist Lord
Hallowgrove	Otto the Flesheater, Parading Corpse	The Weeping Courtier
Brandergard	Tyrannical Executioner, General Harald	The Iron Proctor

Einherjar Mode — this is Mistfall Hunter’s “hard mode” toggle. It bumps all boss HP by roughly 40%, increases their aggression in phase transitions, and improves loot tables. I’ll call out Einherjar-specific differences where they matter.

Hallowgrove Bosses

Otto the Flesheater

Otto is the first real boss most players encounter. He’s a bloated, corpse-stitched brute that patrols the northwestern section of Hallowgrove. His arena is a collapsed cathedral hall with two pillars you can use for cover — but don’t rely on them too much.

Phase 1 (100% — 40% HP)

Otto shuffles toward you with a slow, deliberate walk. His attacks in this phase are telegraphed:

• Overhead Slam — He raises both arms for about 1.5 seconds, then slams the ground. The hitbox extends about 4 meters in front of him. Side-dodge at the last second. If you roll backward, the shockwave still catches you.
• Grab — At close range (within melee distance), Otto lunges forward with both hands. If this connects, he picks you up, bites your character model for roughly 40% of your HP, and throws you. The grab has a 10-second cooldown. Shield classes can block it. Everyone else needs to maintain distance.
• Corpse Belch — A cone-shaped AoE of green bile. Deals damage over time if it hits you. The visual tells are clear — Otto stops, leans forward, and his stomach distends. The cone covers about 120 degrees in front of him.

The key to Phase 1 is patience. I spent my first three attempts trying to burst him down and ate a grab every time. Switch to your ranged weapon stance, kite him around the pillars, and only go in for melee after he commits to the slam.

Phase 2 (40% HP and below)

The transition is unmistakable. Otto roars, his skin rips open along the stitches, and a second pair of arms bursts out of his torso. He now has four arms.

• Double Slam — Two overhead slams in quick succession. The first slam hits the spot in front of him, the second hits slightly to his left. If you dodge the first one straight backward, the second one clips you. Dodge diagonally to the right.
• Spin Attack — Otto rotates his entire body, swinging all four arms in a 360-degree arc. This is the big one. It deals roughly 60% of your HP even through medium armor. The wind-up is about 2 seconds — his body crouches and his arms spread wide. Back off immediately.
• Enraged Charge — At around 20% HP, Otto enters a berserk state. He charges in a straight line toward the nearest player, ignoring all other targets. The charge deals collision damage and ends with a slam. He does this three times in a row before calming down for about 8 seconds.

My Strategy: I run Shadow class with a rapier and crossbow. Phase 1 is all crossbow — stay at max range, plink his head for crits, and only swap to rapier when he does the slam. Phase 2 gets trickier. I save my Shadow Step for the Spin Attack specifically. The i-frames let me phase through it entirely. For the Enraged Charge, I hug the pillars. He destroys them after two charges, but that gives you breathing room.

Loot Table: Otto drops Gyldenblod (always), a chance at Otto’s Carved Femur (a blunt weapon with life steal), and a low chance at Holy Weapon: Ribcage Lantern — a lantern off-hand that pulses light every 8 seconds, revealing hidden traps in a radius around you.

---

Parading Corpse

The Parading Corpse is the second roaming boss in Hallowgrove. It’s a procession of corpse-puppets strung together by mist-thread, controlled by a single puppeteer entity that hangs above the group. You fight the puppeteer indirectly by killing the corpse line.

Phase 1 (100% — 50% HP)

The corpse line has four puppets. Each puppet has individual HP (roughly 1/4 of a normal enemy). The puppeteer above is untargetable until at least two puppets are down.

• Synchronized Swipe — All four puppets attack in sequence. The timing is rhythmic. Once you learn the pattern, you can parry the third hit for a free opening.
• Thread Pull — The puppeteer yanks a puppet backward, pulling any player standing near that puppet toward the center of the group. This sets you up for a surround attack.
• Grave Mist — A fog AoE that the puppeteer spews downward. It obscures vision and slows movement by 30%. The fog lasts 15 seconds.

Phase 2 (50% HP and below)

When two puppets die, the puppeteer descends and becomes targetable. The remaining two puppets become more aggressive — their attack speed doubles.

• Puppeteer’s Lash — A whip attack from the puppeteer with a 8-meter range. It has a wind-up of about 1 second.
• Revival — If you don’t kill the puppeteer within 30 seconds of it descending, it revives one dead puppet. The revived puppet has 50% HP.
• String Slicer — The puppeteer shoots a thread horizontally across the arena. If you’re in its path, it deals 35% HP and slows you. The thread stays for 10 seconds, blocking the area.

My Strategy: AoE is king here. The puppets group tightly at the start. I open with a grenade (the Sticky Fuse works well) to chunk all four simultaneously. Then I focus one puppet down to trigger the puppeteer descent. Once the puppeteer is down, I burn it with everything I have. The 30-second timer forces you to make a choice: kill the puppeteer fast or let it revive and extend the fight.

Loot Table: Parading Corpse drops Gyldenblod, Thread-Strung Pauldrons (light armor with dodge roll cooldown reduction), and a chance at Holy Weapon: Puppeteer’s Grasp — a gauntlet that lets you pull a single enemy toward you on a 20-second cooldown.

Brandergard Bosses

Tyrannical Executioner

The Executioner is a hulking knight in rusted plate armor, carrying a greatsword that’s literally bigger than your character. He patrols the central courtyard of Brandergard.

Phase 1 (100% — 45% HP)

• Executioner’s Cleave — A horizontal slash that covers a 180-degree arc in front of him. The wind-up is long (about 2 seconds) but the damage is devastating — roughly 70% of your HP without armor. The tell is him dragging the sword along the ground, creating sparks.
• Stomp — He raises his foot and stomps the ground. A small AoE around him. Stagger him during the wind-up to cancel it.
• Judgment — At 65% HP, he performs Judgment for the first time. He plants his sword in the ground, and a circle of light appears around him. If you’re inside the circle when the timer ends (3 seconds), you take 50% damage. If you’re outside, you take none. The sword stays in the ground for the rest of the fight, acting as an obstacle.

Phase 2 (45% HP and below)

The Executioner rips his sword out of the ground (if he planted it) and starts two-handing it. His attack speed increases by about 30%.

• Charged Cleave — Same as the regular cleave, but now with a shockwave that travels about 10 meters. The shockwave passes through pillars.
• Executioner’s March — He walks forward slowly, swinging the sword in a continuous pattern. Each swing covers a wide arc. He does this for about 10 seconds or until he hits a wall. The only safe spot is directly behind him.
• Beheading — A single-target attack that deals 90% HP if it connects. The tell is him raising the sword above his head with both hands and pausing for 1.5 seconds. If you’re the target, a red line appears on the ground connecting you to him. Run perpendicular to the line.

My Strategy: The Executioner is slow but punishing. I use the Bonecaster class for this fight — the range lets me stay outside his cleave arc. Phase 1 is straightforward: bait the cleave, punish from behind, back off. Phase 2 is where I see most players panic. The Executioner’s March is scary but it’s actually predictable. Run behind him, get 2-3 hits in, then reset. The Beheading attack is a run-check — if you’re not paying attention to the red line, you’re dead.

Loot Table: Executioner drops Gyldenblod, Executioner’s Greataxe (two-handed weapon, slow but high stagger), and a chance at Holy Weapon: Judgment Bell — a utility item that rings when an enemy is within 15 meters of you, even through walls.

General Harald

General Harald was added in BETA 3 and is arguably the harder of the two Brandergard roaming bosses. He’s a nimble, armor-clad commander with a spear and shield. His arena is the eastern barracks, which has low ceilings and narrow corridors — terrible for ranged builds.

Note: There was a launch day hotfix (July 29, 2026) for an impassable area anomaly in Harald’s arena where a debris pile was blocking access to the eastern supply room. This has been patched.

Phase 1 (100% — 50% HP)

Harald fights with a spear and shield. He’s aggressive but methodical.

• Spear Thrust — A quick, forward-reaching stab. Low damage (about 20% HP) but very fast. The wind-up is barely half a second. This is his primary poke attack.
• Shield Bash — He raises his shield and charges forward. If it connects, you’re staggered for 2 seconds. He follows up with a guaranteed Spear Thrust. The bash deals 15% HP, but the follow-up thrust deals another 25%.
• Commanding Shout — At 75% HP, Harald shouts, buffing himself. For the next 30 seconds, his attack speed increases by 15% and he takes 10% less damage. The shout has a 60-second cooldown.
• Whirlwind Spear — A spinning attack that hits in a full circle around him. Lower damage than the Executioner’s equivalent (about 35% HP) but much faster wind-up.

Phase 2 (50% HP and below)

Harald throws his shield aside and two-hands his spear. His movement speed increases noticeably.

• Impale — A long-range thrust that travels about 12 meters. Harald crouches, aims, then lunges. If you’re hit, you’re pinned to the ground for 3 seconds, taking tick damage. Your teammates can free you by attacking Harald during this window.
• Spear Rain — Harald leaps into the air and rains down spear strikes in a cone. Each strike deals 15% HP. There are 5 strikes total. The pattern is random but the cone is fixed — run sideways, not backward.
• Veteran’s Resolve — At 20% HP, Harald enters a last-stand state. For 15 seconds, he cannot be staggered or interrupted, and all his attacks deal 25% more damage. After 15 seconds, he’s exhausted for 5 seconds — this is your kill window.

My Strategy: Harald is the only boss in the game that punishes passive play. If you keep backing up, his Spear Thrust and Impale will catch you. I stay close, circle to his right (shield side in Phase 1), and punish after his Whirlwind Spear. In Phase 2, the Impale is the run-ender. I keep a Smoke Bomb equipped specifically for this — dropping it breaks line of sight and cancels his targeting. For Veteran’s Resolve, I don’t even try to fight. I run, use healing items, and wait out the 15 seconds.

Loot Table: Harald drops Gyldenblod, Harald’s Campaign Medal (accessory that increases extraction speed by 15%), and a chance at Holy Weapon: Commander’s Banner — a deployable banner that buffs all allies in a 10-meter radius with 20% damage for 30 seconds. Cooldown is 120 seconds.

Mist Lord Encounters

The Mist Lord is the centerpiece of each map. It’s not a boss you can just walk up to — you need to activate it.

How to Access the Mist Lord

Every Mistfall Hunter match has a Mist Lord. It spawns at the center of the map in a sealed chamber. The entrance is a swirling portal of mist — similar to the boss gates in Elden Ring. To open it, you need to defeat a certain number of Corroded enemies in the surrounding area. The exact number varies by map (Hallowgrove requires 8, Brandergard requires 10).

Once the portal is open, any player can enter. The arena locks for 60 seconds after the first player enters. During those 60 seconds, no other players can enter or leave. This is a critical mechanic — it means you cannot be third-partied during the first minute of the fight, but it also means you’re committed.

The Weeping Courtier (Hallowgrove Mist Lord)

The Weeping Courtier is a tall, gaunt figure in tattered noble’s clothing. Its face is a smooth, featureless mask. It moves with an unsettling, gliding walk.

Phase 1 (100% — 60% HP)

• Tear Volley — The Courtier raises a hand and fires a spread of 6 tear-shaped projectiles. Each projectile deals 10% HP. The spread is tight at close range, wider at distance. At mid-range, you can dodge through the gaps.
• Mist Step — The Courtier teleports behind the nearest player. This is instant — no wind-up. It always follows up with a melee swipe. If you’re solo, turn around immediately after the teleport and block or dodge.
• Sorrowful Aura — A passive aura that builds up a “Despair” meter on any player within 8 meters. At full Despair, your movement speed is halved for 10 seconds. The aura pulses every 3 seconds. You can reset the meter by leaving the aura radius.

Phase 2 (60% HP and below)

The Courtier’s mask cracks, revealing a weeping face underneath. It starts leaving mist trails everywhere.

• Mist Trail — The Courtier leaves a trail of mist wherever it walks. The trail lasts 20 seconds and deals 5% HP per second if you stand in it. The arena gradually fills with these trails.
• Wailing Burst — A large AoE centered on the Courtier. The wind-up is 3 seconds, during which a circle appears on the ground. If you’re inside when it detonates, you take 60% HP and are knocked back. The Courtier cannot move during the wind-up.
• Summon Reflection — At 30% HP, the Courtier summons a mirror-image of itself. The reflection has 30% of the Courtier’s HP and uses Tear Volley and Mist Step. It does not have the Mist Trail or Wailing Burst. Kill the reflection fast — it doesn’t despawn on its own.

My Strategy: The Weeping Courtier is a DPS check disguised as a mechanics fight. The Sorrowful Aura forces ranged players to keep moving, but melee builds suffer. I run Feral Scion for this fight — the high mobility helps me manage the Despair meter. In Phase 2, the arena fills up fast. I try to bait the Wailing Burst near the edges of the arena so the mist trails are concentrated there, leaving the center clear. The Reflection at 30% is the real threat. I save my ultimate ability for this moment.

Loot Table: The Weeping Courtier drops Gyldenblod (large quantity), Courtier’s Weeping Mask (head armor that reduces Despair buildup by 50%), and a guaranteed chance at a Holy Weapon (random from the Hallowgrove pool).

The Iron Proctor (Brandergard Mist Lord)

The Iron Proctor is a massive, clockwork-like construct. It’s easily the largest boss in the game — about three times the height of a player character. It resides in the Grand Cathedral at the center of Brandergard.

Phase 1 (100% — 65% HP)

• Cog Slam — The Proctor raises its left arm (which is a massive gear) and slams it down. The slam creates a shockwave in a straight line. The shockwave travels about 15 meters.
• Gear Spit — The Proctor’s chest opens, and it launches a spinning gear at the nearest player. The gear homes in slightly and deals 25% HP on impact. It can be destroyed with 3 hits.
• Mechanical Precision — Every 20 seconds, the Proctor “locks on” to a player. A red reticle appears over that player’s head. For the next 5 seconds, the Proctor’s next attack against that player is guaranteed to crit. The targeted player should go defensive.

Phase 2 (65% to 35% HP)

The Proctor’s outer shell falls away, revealing a glowing core. It moves faster now.

• Cog Storm — The Proctor spins rapidly, sending gears flying in all directions. Each gear deals 15% HP. The storm lasts 4 seconds. The only safe spot is directly under the Proctor — the gears don’t hit there.
• Gravitational Pull — The Proctor’s core glows, and all players in the arena are pulled toward it over 3 seconds. At the end of the pull, it detonates a shockwave. The pull is strong enough that you can’t run out of range. Instead, time your dodge roll at the moment of detonation.
• Overheat — The Proctor vents steam from its joints. The steam deals 5% HP per second and creates a heat haze that obscures vision. The vents last 10 seconds.

Phase 3 (35% HP and below)

The Proctor goes into emergency mode. Its core is exposed and glowing red.

• Self-Destruct Protocol — The Proctor begins a 30-second countdown. If it reaches 0, the Proctor explodes, dealing 100% HP damage to everyone in the arena. The only way to stop it is to deplete its remaining HP.
• Rapid Cog Spit — The Proctor fires gears every 2 seconds instead of every 8 seconds.
• Crush — The Proctor raises both arms and brings them down on a targeted area. The area is indicated by a red circle on the ground. The attack deals 80% HP and stuns you for 3 seconds if you’re in the circle.

My Strategy: The Iron Proctor is the longest boss fight in the game. I bring at least 3 healing items. Phase 1 is about positioning — stay behind the pillars to block the Cog Slam shockwave. Phase 2 requires good reaction time for the Gravitational Pull. The dodge timing is tighter than it looks — I practiced it in low-stakes runs until I got it consistent. Phase 3 is a pure burn. I pop all my damage cooldowns, use my Holy Weapon if I have one, and pray. The 30-second timer is generous but the pressure makes you panic.

Loot Table: The Iron Proctor drops Gyldenblod (large quantity), Proctor’s Core Shard (gem socket that adds 10% cooldown reduction), and a guaranteed chance at a Holy Weapon (random from the Brandergard pool).

Einherjar Mode Boss Differences

Einherjar Mode is Mistfall Hunter’s answer to players who want harder content. I’ve run it about 10 times now. Here’s what changes for bosses:

• All bosses have 40% more HP. The phase transitions happen at the same percentage thresholds, but the total HP pool is much larger.
• Phase transitions are faster. The recovery window between phases is cut from roughly 3 seconds to 1 second. You can’t use that window to heal anymore.
• Additional attacks in Einherjar:
  • Otto gets a third phase at 15% HP where he explodes into a swarm of insects for 10 seconds, becoming untargetable.
  • The Parading Corpse summons two additional puppet pairs when the puppeteer descends.
  • The Tyrannical Executioner’s Judgment now leaves a burn effect on the ground inside the circle that lasts for the rest of the fight.
  • General Harald’s Veteran’s Resolve lasts 20 seconds instead of 15.
  • The Weeping Courtier summons two Reflections at 30% HP instead of one.
  • The Iron Proctor’s Self-Destruct countdown is 20 seconds instead of 30.
• Loot is better. Einherjar bosses have a 30% higher chance to drop Holy Weapons and a guaranteed drop of Holy Forging Materials, which are used to upgrade Holy Weapons.

Loot Table Summary

Boss	Guaranteed Drop	Unique Drop	Holy Weapon
Otto the Flesheater	Gyldenblod	Otto’s Carved Femur	Ribcage Lantern
Parading Corpse	Gyldenblod	Thread-Strung Pauldrons	Puppeteer’s Grasp
Tyrannical Executioner	Gyldenblod	Executioner’s Greataxe	Judgment Bell
General Harald	Gyldenblod	Harald’s Campaign Medal	Commander’s Banner
Weeping Courtier (Mist Lord)	Gyldenblod (large)	Courtier’s Weeping Mask	Random Hallowgrove Holy Weapon
Iron Proctor (Mist Lord)	Gyldenblod (large)	Proctor’s Core Shard	Random Brandergard Holy Weapon

Holy Weapons are the endgame chase items in Mistfall Hunter. They’re not guaranteed drops — the base chance is about 5% from roaming bosses and 15% from Mist Lords. Einherjar Mode bumps those to 8% and 20% respectively. Each Holy Weapon has a unique effect and can be upgraded with Holy Forging Materials.

General Boss Tips

1. Always bring a ranged option. Even if you’re a melee-focused class, having a crossbow or magic staff lets you safely damage bosses during dangerous phases. The General Harald fight taught me this the hard way.

2. The 60-second arena lock is your friend and your enemy. It keeps other players out, but it also means no one can save you. If you’re running a squad, make sure everyone is ready before entering. If you’re solo, accept that you’re on your own.

3. Learn the boss runbacks. The extraction mechanic means you lose everything if you die without extracting. But if you die to a boss, your teammates can still pick you up. The revive window is 30 seconds. After that, you bleed out and your gear is on the ground.

4. Respect the Despair meter on the Weeping Courtier. I ignored it my first two attempts and ended up moving like a snail while the Courtier wailed on me. The meter fills faster than you think.

5. The Iron Proctor is easier with a squad. Solo, the Gravitational Pull into the shockwave combo is brutal. With 3 players, only one person gets targeted by the pull, and the others can free-damage the Proctor during the wind-up.

6. Save your ultimate for phase transitions. Almost every boss has a dangerous window when they transition phases. Burning your ultimate during this window can skip the worst attacks.

What I’m Still Not Sure About

This section is for the things I’ve observed but haven’t fully confirmed. Mistfall Hunter is a week old as of writing, and the community is still figuring things out.

• Mist Lord spawn conditions. I’ve had matches where the portal opened without me killing the required number of Corroded enemies. It might be proximity-based, or other players’ kills might count toward the threshold. The 8/10 number I listed is the most commonly reported, but I’ve seen it vary.
• Holy Weapon drop rates. The 5% and 15% numbers are based on community polling in the Discord. I’ve personally gotten 2 Holy Weapons in about 40 runs, which comes out to roughly 5%. But the sample size is small.
• General Harald’s arena hotfix. The patch notes mentioned an “impassable area anomaly” fix. I’ve tested the eastern supply room and it’s accessible now. But I haven’t confirmed what was in there — some players say it was a loot cache, others say it was a shortcut.
• Iron Proctor Self-Destruct damage. I’ve seen claims that it’s not 100% kill — that high-damage reduction builds can survive it. I haven’t tested this myself. If you’re running a tank build with max armor, let me know.
• Einherjar Mode boss HP scaling. The 40% number is a rough estimate from comparing kill times. I haven’t datamined the actual values. It could be as low as 30% or as high as 50%.

The Bottom Line: Play to Your Boss’s Weakness, Not Your Class’s Strength

Here’s the thing about Mistfall Hunter’s bosses that took me the longest to learn: the game rewards adapting to the boss, not forcing your class’s preferred playstyle. I spent my first 10 hours trying to make my Shadow class work against every boss with the same rapier-and-crossbow combo. It worked fine on Otto. It failed miserably on the Iron Proctor.

The bosses in this game are designed to expose specific weaknesses in your build. Otto punishes close-range greed. The Parading Corpse punishes single-target focus. The Executioner punishes slow reaction times. General Harald punishes passive play. The Mist Lords punish everything at once.

The players I see succeed consistently are the ones who swap their loadout based on which boss they’re hunting. They bring a shield for Otto. They bring AoE for the Parading Corpse. They bring mobility for the Weeping Courtier. They bring healing items for the Iron Proctor.

Mistfall Hunter is a game about preparation as much as execution. The bosses are beatable. They’re all beatable solo. But you need to respect what each one demands from you, and you need to come prepared.
