Slay The Spire 2 Multiplayer Black Screen Fix
Some Slay the Spire 2 multiplayer runs suddenly load into a black screen instead of the map. The music continues playing and the cursor still moves, but the game never actually starts.
This issue usually appears after loading into a multiplayer run that previously worked, especially when continuing a run that was already in progress.
Slay The Spire 2 Multiplayer Black Screen Fix
The multiplayer black screen bug in Slay the Spire 2 is commonly caused when a player reaches 9 potion slots during a run, which can break the run when the game loads the next map node.
Players report the screen going black after loading a run where someone had a relic or reward that pushed their potion slots to 9. Once the run reaches that point, the game loads into a black screen with music playing and no interface.
The run often becomes impossible to continue unless the potion slot situation is avoided.
What The Black Screen Bug Looks Like
The bug appears in a very specific way during multiplayer runs. Everything seems normal until the run finishes loading.
Players usually see the following:
The multiplayer lobby works normally
Everyone readies up successfully
The loading screen appears
The run finishes loading
The screen turns completely black
The cursor still moves and music continues
No map or UI appears
Only closing the game works
At that point the run cannot continue.
Why The Bug Happens
Reports from multiplayer players point to potion slot limits as the most common trigger.
The problem usually appears when a player reaches 9 potion slots through relics or rewards. After the run moves to the next map location, the game can fail to load properly for everyone in the lobby.
This often happens after events like:
Opening a chest
Leaving a shop
Finishing an elite fight
Collecting relic rewards
Once the run reloads after these moments, the black screen can occur.
Possible Workaround That Players Found
Some groups managed to avoid the bug by preventing a player from reaching 9 potion slots.
If the run loads right before a reward choice, try selecting a different reward that does not increase potion slots.
Players who avoided picking up the extra potion slot relic were able to continue the run normally.
Possible workaround steps include:
Restart the game
Reload the multiplayer run
Avoid choosing relics or rewards that increase potion slots to 9
Continue the run with fewer potion slots
This does not permanently fix the bug but it can allow the run to continue.
Final Blurb
The Slay the Spire 2 multiplayer black screen bug usually appears when a player reaches 9 potion slots during a run. When the game loads the next map node, the run can fail to initialize and leave everyone stuck on a black screen.
Avoiding the extra potion slot relic or reward appears to prevent the issue in many cases, allowing multiplayer runs to continue normally.
