Exploring Ratlantis and Its Loot
Reaching Ratlantis
Ratlantis is a late-game dimension. You need a Gem of Ratlantis to activate the portal. Gather Oratchalcum Ore, smelt it, and craft Block of Oratchalcum for portal framing. Chunky Cheese Token blocks are also tied to Ratlantis progression.
Once inside, expect hostile Feral Ratlantean mobs and the boss Avatar of Ratlantis. Bring strong gear: Axe of Ratlantis, Bow of Ratlantis, Chestplate of Ratlantis, and Boots of Ratlantis are the dimension's signature equipment set.
Loot and Materials
Ratlantean structures contain Archeologist Hat, Ancient Sawblade, Arcane Technology, and Feral Ratlantean Bagh-Nakhs. Feral Rat Claw drops from Feral Ratlanteans and is used in crafting.
Corrupt Rat Skull and Brain Block are decorative or crafting components found in Ratlantis ruins. Marbled Cheese building blocks appear throughout the dimension's architecture.
Defeat the Avatar of Ratlantis to obtain high-tier rewards. Gem of Ratlantis is the key item for returning or expanding portal access. Stock Cheese and Blue Cheese before entering — rats you bring along will need food to keep working.
