The Best Mods on the Steam Workshop

Slay the Spire 1 had one of the best modding scenes in the genre, and the sequel is off to a fast start: the STS2 Workshop already has over 1,500 items. Since the game supports Workshop mods natively, installing any of these is one click, no launcher required.

Here are the mods worth your subscription right now, based on what the Workshop community is actually subscribing to, plus the one we build ourselves.

The top community mods

BaseLib and RitsuLib by Alchyr and OLC sit at the top of the subscriber charts for a simple reason: they are the frameworks most content mods are built on. You will rarely interact with them directly, but half the mods below list them as dependencies, so grab them first.

Quick Restart 2 by (Gk) Erasels does exactly what the name says: restart a run instantly instead of clicking back through menus. If you practice specific matchups or reroll starts, this saves real time every session.

Regent FX Omnistar by Vitech[CN] is the most subscribed visual mod, a full effects overhaul for the Regent. If you main the star throne, this is the drip.

Downfall by lamali carries the most famous name in Spire modding. The original Downfall was the play-as-the-villains expansion for STS1, and the team is building on the sequel now. Watch this one.

Minty Spire 2 by (Gk) Erasels and Intent Graph by Chaofan are the quality-of-life picks: extra run information and clearer enemy intent data. If you care about making better decisions with better information, these are for you. Better Mod Menu by Crunchmybeloved rounds out the toolbox if you end up running more than a few mods at once.

The Spire Codex Mod

We built the SpireCodex companion mod, and it does a different job than everything above: it connects your game to this site.

With the mod subscribed:

• Your finished runs upload automatically and count toward the community stats, tier list, and leaderboards. Sign in with Steam once and every run attaches to your profile.
• Friends can spectate your climb live at spire-codex.com/live: your map, deck, hand, fights, and shop decisions, updating as you play. If you stream, viewers can follow along without squinting at your VOD.
• In-game stat lookups show you the community's win and pick rates for the cards and relics you are offered, filterable by skill bracket, so "is this card actually good at A10" gets answered on the reward screen.
• After a win, you get a shareable run page with your full deck, route, and per-floor history.

None of it touches gameplay or difficulty, so it stacks cleanly with everything else in this list.

Installing mods

Subscribe on the Workshop page, launch the game, and enable the mod in the mods menu. Slay the Spire 2 is in early access, so patches occasionally break mods for a few days; if something misbehaves after an update, check the mod's Workshop page before assuming your run is cursed.

If you build something for STS2 yourself, whether a mod, a bot, or a tool on the Spire Codex API, tell us and we will feature it on the community showcase.
