Ascension

Ascension is a difficulty mechanic unlocked once a player beats the game for the first time. Each Ascension level is unlocked by beating the previous one, with the effects of each Ascension level stacking with the previous.

Ascension levels may be chosen in the lobby before starting a run and may be freely raised or lowered. Beating Ascension 5, 10 and 15 unlocks a badge and upon completing 15, the winning text is replaced with WW91ciBhc2NlbnNpb24gbGV2ZWwgZGlkIG5vdCBpbmNyZWFzZS4=, which translates to "Your ascension level did not increase."

Beating certain ascensions may give badges.

Beating acension 0 (normal mode) or acension 15 gives you the option to show off with a custom badge on the class you used to beat the game on that acension.
