Multiplayer - Together in Spire - Now with Steam!

Discord Link:

Multiplayer comes to Slay the Spire!

Together in Spire is a mod that allows you to Slay the Spire with up to 10 friends! This mod provides a multiplayer lobby where you can join your teammates and kill monsters, working together to achieve crazy combinations!

The mod is being actively worked on with new features coming all the time, and there's always bound to be a few bugs.

I intend to keep the mod as vanilla as possible by avoiding adding new content and making the game multiplayer, while still including some unique mechanics expected from a MP environment such as:
- Custom UI
- Card, Relic, Gold and Potion Trading
- Reviving
- Game Saving
- and much more to come!

I HIGHLY recommend joining our discord as there's plenty of important information there:
* mod installation guide
* mod FAQ
* bug reporting and crash logs
* general chatter

Once again, the discord link is:

The mod also attempts to support other mods, however some mods are too complex to function alongside TiS. If you're a mod creator and wanna patch your mod for Multiplayer, contact me on discord. With your help, even more mods will be officially supported in the future!

Lastly, if you wanna help support the mod, consider joining my patreon for exclusive testing updates and previews!

And that's about it!

Encountered a bug, against Time Eater, using a turn ending card as 12th card resulted in me not being able to play any cards in the next turn.

@Draco9990 The Time Eater boss would gain 2 strength when any one of the players triggers his "Time Warp" ability, similar to the Awakened One's "Curiosity" and the Gremlin Nob's "Enraged". These monsters can become extremely tough when the number of players goes up. Just wondering is this by design, or is it maybe better if we can somehow put a limit on their strength growth?

Thanks for the mod by the way, me and my friends absolutely love it!

@Pootenheimer and @Kyoojin, thank you for the detailed descriptions! I'll investigate the issue and fix asap!

@Hun if you submit a log in the discord I can take a look at it! If you're not playing with other mods, that's definitely not intended, and if you are, I'd love to add the mods to the compatibility list.

@Draco9990 - I was in the game with Kyoojin, I put details of our experience in a new Discussion (was over 1000 characters).
Kyoojin Nov 22 @ 4:05pm 
@Draco9990 We would find on combat encounters with multiple enemies the HP would vary between people's game. A pack of 3 would have one alive that was not alive for every one else.
The turns for the four of us would have two that could go together while the other two people had to wait for everyone to complete their turn before they each could go individually. The encounters we noticed issues were the Three Sentries, Slime boss, Gremlin leader, and the Collector.

I am on the discord server for Together in spire and can send any log files if you want them. We are trying different things when we load it up to see if we can reliably reproduce the issue.

It's a nice mod. But my friend always disconnected and failed to reconnect. That's so annoying especially we reach the third floor

@Kyoojin could you please elaborate in what way the games would de-sync? I'm currently not familiar with the issue so I need more information if possible!
Kyoojin Nov 21 @ 4:53pm 
Great mod, thank you for making it. Wanted to report some issues we were having. We were playing a 4 player game and found we would frequently de-sync between us. Two people are playing in the same house on steam decks 2 by PC in a different location.

Snecko skull artifact seems to be bugged and doesn't share poison from it to other players
