Rockwell is the end boss of Aberration, and he inverts the usual Ark difficulty curve. The health numbers are the smallest of any boss arena in the game. The tribute list is the most demanding.
The stats (from the wiki dataset)
| Difficulty | Health |
|---|---|
| Gamma | 42,000 |
| Beta | 68,500 |
| Alpha | 115,000 |
The encounter total spreads across his phases and tentacles, so the bar you burn is not the whole fight. Do not read the small number as an easy boss.

The real difficulty: the supply chain
Every trophy item is an Aberration-specific drop from a creature that can kill you:
- Nameless Venom — from nameless, the map’s ambient predator. You will have fought dozens by the time you have twenty venom, and every one of those fights was a risk.
- Reaper Pheromone Gland — from reaper kings, the map’s signature stalker enemy. Glands are also what you need for reaper pregnancies, so demand competes with itself.
- Rock Drake Feather — from rock drakes in the lower regions, which are the map’s endgame area.
- Basilisk Scale — from basilisks, which fight underground with a gaze attack.
By the time the tribute is assembled, you have already survived everything Aberration can throw at you. That is the design.
The fight
The arena is the Rockwell arena on Aberration, and the encounter is element-themed:
- Tentacles. His health spreads across his own body and the tentacles that share the arena, which is why the numbers read low.
- Element-based attacks. Expect corruption and ground hazards rather than straightforward melee.
- Phases. The fight moves through stages rather than staying static, so positioning is a moving target.
Bring a loadout built for sustained damage and healing rather than burst. The fight is shorter than the Island bosses but denser.
