The entire world is a tower, and progression is linear - you climb it floor by floor. Ice caverns, jungles, deserts, underwater ruins, pirate archipelagos, candy forests, floating chaos dimensions, a broken heaven and a war-torn ocean: every floor is a new chapter with its own monsters, bosses, quests and secrets, gated by a floor boss.

Along the way: instanced dungeons and a raid, field bosses, ritual altars, secret rooms, mining, fishing and herbalism, naval combat with your own upgradeable ship from Floor 8, and factions to win over - two of them at war on the final floor.

Every monster can drop a card - build-defining passives, procs and autocasts across four rarities. Equip a deck of four and shape a playstyle nobody else is running: turret summoner, crit engine, plague spreader, storm caller. Scrap duplicates, upgrade your deck slots, and chase the 0.5% legendaries.

See what the strongest players run on the Builds page, or draft your own in the Planner.

The endless endgame: a deck-building roguelike beneath Haven. Spend keys of rising tiers, stack map modifiers for richer rewards, survive hordes, gauntlets and a boss every fifth depth. Abyss Coins buy a permanent upgrade deck that grows run after run.

Depth is the ladder: top 50 each season earn the Abyss Vanguard title - the top 3 become The Voidcrowned, stamped forever.
