Decision lab / patches
A change list is not a decision.
Patches describe what changed. Players need to know what to do differently. This page maps verified changes to the systems, content, and run decisions they actually alter.
| Change | What was touched | Player consequence |
|---|---|---|
| Boss replacement | Aeonglass replaced Doormaker in a major update | Roster prep, route planning, and deck answers shift. |
| Workshop | Workshop content was added in a major update | New build and crafting options change run planning. |
| Bestiary | Bestiary content was added in a major update | Encounter knowledge changes, not just the list. |
| Multiplayer | Co-op scaling and rules were changed in a major update | Party decisions use new scaling boundaries. |
| Balance | Card and relic balance values were adjusted | Old rankings no longer match current value. |
Impact model
Three steps from patch to decision
| Step | Question | Output |
|---|---|---|
| Changed system | Which system the patch touched | Start here to find what to re-check. |
| Affected content | Cards, relics, Bosses, events, or multiplayer touched | Narrow the change to what you actually use. |
| Run decision | The practical choice the change alters | Rewrite only the decision that changed. |
FAQ
Patch impact questions
How do I read a patch as a player, not just a change list?
Map each change to the system it touched, the content it affected, and the run decision it alters. A raw change list is not the same as knowing what to do differently.
What did the major update change for Bosses?
The update removed Doormaker from Act 3 and added Aeonglass in its place. Boss preparation and route planning must use the current roster.
Does a patch invalidate old card and relic rankings?
When a patch adjusts balance values, an old ranking no longer matches current value. Re-check card and relic advice against the version you are playing.
Which systems did the major update touch?
The update covered Workshop and Bestiary additions, the Boss replacement, enemies, multiplayer, and balance changes. Each of those changes a different run decision.
How do I stay current between updates?
Track the version label on any advice you use, and re-check a system after each update rather than trusting a summary written against an older build.
The ledger keeps it current
Version changes touch cards, relics, Bosses, and multiplayer together. Read the ledger to keep a patch from turning into stale advice.
