Eternal Palace Sakura Mugen Depth

Mugen Depth is the labyrinth's risk meter. The store page states that as you go deeper, Mugen Depth rises and brings debuffs plus stronger enemies, so each push trades safety for reward. Official screenshots show a Mugen Depth value and a countdown bar labeled Until Depth Effect.

The developer presents Mugen Depth as the reason runs stay tense: going further raises both danger and the chance at better spoils. The exact numerical thresholds for each debuff are not listed on the public store page, so this guide only names the system as the developer describes it.

Bosses and endgame challenges are described as waiting on the deepest floors, which is where high Mugen Depth pressure matters most.
