Endless Abyss has no floor cap: every level hides a red gate deeper, there is no shrinking darkness, and the exit stays open so you can bank the run any time.
Endless Abyss is a run tier with no floor limit. Every level keeps a red gate to the next one, so the run ends when you decide it ends — or when you die.
Past the fourth floor, monster health and damage keep compounding with depth, and depth pays you back: gold and experience scale with how far down you are, and the loot rarity floor rises one tier every four extra floors (capped at epic — legendaries still come only from bosses and treasures). Each deep floor is held by an endgame boss, so the descent reads as a chain of boss fights rather than a clear-the-map crawl.
There is no shrinking darkness down here, and the blue extraction gate is open from the moment you land. Sweep a whole floor or leave the second you arrive — the only reason to stop is deciding your bag is heavy enough. Death still drops everything you carry; the rules are in the beginner guide.
The week's abyss is generated from a weekly seed and is the same dungeon for everyone: biome bands rotate every two to three floors, and each floor's layout holds for the whole week, which is what makes the board comparable. The weekly abyss board ranks deepest floor reached and resets when the week rolls over.
Charge attacks, weapon coating and bleed/sunder stacks all matter more the deeper you go — see advanced mechanics. Start a run.
