Custom Mode

Custom Mode is a game mode unlocked by playing a Daily Climb. It allows the player to choose any number of custom modifiers, including Daily modifiers, to their run. It also allows them to customize Seed, Character and Ascension levels beyond those unlocked.

Playing on Custom Mode disables Achievements and the Leaderboards.

Mods on the table below with a * next to them are Daily modifiers and may be selected for Daily Challenges.
