King Dozer

King Dozer has 7,500 health, no elemental weakness, and a single weak point on the eyes, and he gets harder to hurt as the fight goes on. He is a tier 3 horned lizard, the second intended optional boss after Axl, and the only fight in the game whose damage resistance scales with your progress through it.

That last part is the whole thing, and most fight guides skip it:

So the last third of his health bar costs you more than two and a half times the damage the first third did. A burst opener does not shorten this fight much, and bringing enough healing to survive a long phase 3 matters more than bringing a bigger weapon. Each phase transition also breaks water inlets around the arena, and how many break scales with the party size, so a solo run and a four-player run do not fight in the same room.

What he resists

He drops Searing Stone and shrugs off Sizzle entirely, which tells you what he is: leaving the Spicy weapon at home is the single biggest upgrade most players can make to this fight. Blunt damage is not on the list, so a club and shield is the standard answer, and the eyes are where it has to land. The Spicy and Explosive halvings are confirmed by two independent databases; the Water figure appears in only one, so treat it as the softer number.

Getting in, and starting it

The den is a cave in the northeasternmost corner of the Greenhouse Surroundings, and the gate needs a tier 2 Omni-Wrench, which is the real gate on this fight rather than your gear. The encounter itself is triggered by using a Goopy Gobbler on the pedestal near the arena entrance, so you can walk in, look at it, and leave.

Stun threshold 275 is the highest in the game, more than two and a half times General Berserker's 90, and the cooldown is 120 seconds. Plan on one stun per phase at best. This is not a fight you stagger your way through.

Drops

King Dozer's Light is the trophy drop and it is a 1% roll, so if you want it, you want it from a boss you can clear repeatedly rather than from a first kill.

Health, tier, phase thresholds, resistances, the stun values and the loot table were read off the Grounded Wiki's King Dozer page on 2026-10-26 and cross-checked against the Metaforge creature database, which agrees on health, tier, stun and the Spicy, Explosive and Slashing figures. The handling advice is from published fight reports rather than a stat block. See the full boss list, or damage types for what blunt actually means here.
