Abyssal Pool Map Guide

The Abyssal Pool is an underwater labyrinth of drowned ruins, lost idols, and mutated monsters. While individual run layouts vary procedurally, biomes follow consistent depth tiers with predictable resource types, enemy populations, and altar locations.

Maps collected during dives upload to the Library, revealing explored branches. Systematic exploration beats random deep diving — uncover every branch in a biome before blessing it or pushing to the next depth tier.

The Shallows — starting biome, Iron Ore, Planks, first Idol, Killer Algae, Rain-Touched. Eastern Farmlands and Stalker Wells gate mid-game shafts. Graveyard and Crimson Basin hold late pressure. The Chasm and Endrain Village close the deepest routing and ending beats.

Read the dedicated Rain Serpents page before you spend a day hunting a gate that has not spawned. Dive Points on the Diving Deck skip transit once you have discovered the spot. Without Tier 3–4 Deck access, deep Idols cost prohibitive oxygen on transit alone.

Follow heartbeat audio for Eldritch Idols. Follow whispers for underwater altars. Snails unlock one-way shortcuts once opened from the correct side. Destructible beams need Corrosive Darts. Use boost sparingly in unfamiliar branches and upload Map fragments to the Library after every productive dive.
