Data status: This page explains mechanics and decision rules. Where a precise number matters we say so and mark it, rather than guessing.

A large balance pass

Repentance shipped with a wide balance pass. It changed many items that older guides still describe.

Advice from earlier versions can be outdated. Check which version a tip assumes before you follow it.

Reworked items

Some items gained new effects or lost old ones. A build that worked before may need a fresh plan.

The rework touched both weak and strong items. Treat any single-item claim as version specific.

New characters and paths

Repentance added new characters and new routes. These open content that earlier runs cannot reach.

New paths also added bosses and endings. They give a long-time player a reason to start again.

What still holds

The core loop did not change. You still clear floors, spend pickups, and choose a path down.

Mechanics like damage and tear rate still work the same way. Learn those first, then absorb the version differences.

Next: How a run works and Unlocking progression.
