Mechanics
Endless Archive
Uncapped floors after the chapter 12 ending: doctrines, modifiers, revision battles, staking, rebinding and Endless upgrades.
Unlocking
Unlocks after recording the chapter 12 ending. Your strength at unlock sets the initial baseline. Depth is uncapped; Endless upgrades and the highest depth persist through rebirth.
Doctrine
Every five floors, choose a doctrine for the next five. The first edition requires manual selection; automatic binding unlocks after the first rebind, with priorities configurable in automation settings.
Modifiers and revision battles
Each edition has two modifiers that change on rebinding. Every 25 floors, an empowered main-story boss appears as a revision battle.
Staking
The bonus binding thread grows as you keep winning, with streaks counted up to 12. Defeat loses only the bonus; base thread remains. You can bank the bonus at any time with Bind Here.
Rebinding and Endless Upgrades
Rebinding from floor 6 onward resets the dive to floor 1 and converts collected thread into binding thread at 5 to 1. Spend binding thread on uncapped Endless upgrades. Data is available in Endless Archive data.
