Biome
Boss arena. One Collector Leviathan, no respawn. The hardest single-target encounter in the build.
The Collector Leviathan Arena is a dedicated boss biome. Population caps are hard-coded to exactly one Collector Leviathan; killing it does not respawn it in the current build.
The arena contains a Pearl Stash as its hidden objective. The Leviathan defends it actively and routes between hiding spots tagged AI.Target.HidingSpot.Leviathan.
Bring the highest hull rating you can build. Most successful kills use repeated Tadpole ramming runs from outside the arena's threat radius rather than a sustained melee.
Overgrown Ruins
Sunken Axum architecture wrapped in coral, with mid-depth power-plant chambers and root-canyon caves.
Coral Gardens
The bright, biodiverse Shallows-tier biome. Highest creature variety in the build and the heartland of the cooking pipeline.
Sparse Plains
The Clamily mid-depth flats. Lower creature density, more open water, and rarer mineral deposits.
Deep Start
The depth-rated descent corridor down to the Void. Where Tadpole crush warnings start firing.
