S Tier — Hardest Bosses
The biggest first-playthrough walls. These are the fights most likely to punish weak resource management, greed, or inconsistent movement.
#1 Mined Mind
Our #1 first-clear difficulty pick. The fight creates sustained pressure and gives very little room for repeated mistakes, so clean movement and disciplined damage windows matter more than trying to race the boss.
#2 Frozen Horror
A severe execution check that arrives late enough to expect strong fundamentals. A better build helps, but bad timing is still punished quickly.
#3 The Congealed
A required late-game wall rather than an optional challenge. The fight asks for movement, pattern recognition, and resource discipline at the same time.
#4 Thalassion
An optional encounter that can punish even well-prepared players. Because it is optional, many players reach it with very different builds and progression levels.
#5 Furgus the Faithful
A demanding late-game fight inside an already exhausting region. Mistakes are expensive when your focus and healing resources are already under pressure.
A Tier — Very Hard
Serious walls that become more manageable once the core pattern or arena problem is understood.
#6 Nox's Beast
A strong early-to-mid-game wall with dangerous arena pressure and enough punishment to expose sloppy movement.
#7 The Carving Man
Fast pressure and a fight that punishes panic. It gets much easier once you stop forcing attacks and read the timing.
#8 Locomotress Agnes
Movement-heavy pressure makes careless positioning expensive and can make the fight feel chaotic before the route becomes familiar.
#9 Dark Deluxy
A difficult optional encounter that rewards preparation. See the Dark Deluxy guide for a dedicated breakdown.
#10 Baron Lionel
A fast late-game duel where missed reads can snowball quickly, especially if you enter the sequence with a weak recovery plan.
B Tier — Moderate
Real boss fights that demand attention, but usually become consistent after their central gimmick or rhythm is learned.
The Duchess of Queensbury
An important early difficulty step that teaches proper dodge-and-punish rhythm.
Mock Moon
Tricky at first, but much easier once the encounter rhythm becomes familiar.
Madd House
A memorable encounter with enough environmental and execution pressure to punish players who ignore the arena.
Major Miner
A solid mid-game test with manageable patterns once you stop overcommitting.
Lumenarks
A later encounter that rewards pattern recognition more than raw damage output.
Armand · Midden · Mirren · Wonder Willis · Maxi · Evra the Undying
These optional fights can be dangerous when discovered early or unprepared, but usually sit below the game's largest progression walls.
C Tier — Easier Once Understood
Bosses or recurring encounters that are still meaningful, but generally create less first-clear pressure than the tiers above.
The Dugin
A unique optional encounter with an unusual setup, but not one of the largest mechanical walls once you understand what is happening.
Thorne
Important narratively, but the earlier fight functions more as a combat check than an endgame execution wall.
Nether Kraken
Visually intimidating, but comparatively manageable after its attacks are understood.

Recommended Before Hard Bosses
If a boss feels unfair, stop forcing attempts for a moment. A better weapon, safer Trinket setup, more healing capacity, or a different Sidearm can turn a frustrating wall into a learnable fight.
