Mechanics
Rebirth and permanent upgrades
What rebirth retains and resets, Memory Points, permanent upgrades, imprints and contradictions.
When to reincarnate
Rebirth becomes available after defeating four chapter rulers in the current run. The first entry into Act II requires rebirth and one permanent upgrade level. Later rebirths are optional once the same four-boss requirement is met. Settings control whether to return home automatically afterward.
What is retained and reset
- Retained: Memory Points and permanent upgrades, discovered choices, Echoes, Endless upgrades and highest depth, feats, titles and other records.
- Reset: current chapter progress, producers, resources and story choice effects.
The rebirth screen shows the Memory Points you would currently receive and their breakdown.
