What are the best Slay the Spire mods? Whether you’ve exhausted the game and are looking for extra content, or just want to make some small changes to an otherwise perfect experience, the best Slay the Spire mods can fit the bill.

The roguelike card game has official Steam Workshop mod support and a fantastic community, meaning there are tons of mods available to easily integrate into the indie game. These mods range from making the map easier to read to huge expansions featuring brand-new characters. There are hundreds to choose from on Steam, but we’ve picked out the very best mods in Slay the Spire just for you.

Here are the best Slay the Spire mods:

Spire with Friends

If you ever want to prove who the best Slay the Spire player is among your mates, Spire with Friends makes this task dead simple. While this is technically doable in the base version of the game using seeds, this mod does all the hard work for you. Featuring support for up to 200 players in a competitive speed running style versus mode, you can watch in real-time as each player makes their way up the spire. Whether you’re going for a Heart run or you want to see who can climb the spire the fastest, this mod finally gives you the chance to prove who the best player is.

Spire Biomes

Spire Biomes introduces biomes to Slay the Spire’s map, dividing progression nodes into colorful zones with new modifiers. These modifiers can vary in complexity, but typically introduce new events, monsters, and rewards that force you to switch up your old strategies for a fresh approach. There’s even a built-in mod configuration menu, so if you don’t enjoy a particular biome, you can just disable it and enjoy everything else that Spire Biomes has to offer.

PvP in the Spire

Taking on the pre-programmed denizens of Slay the Spire is all well and good, but TCG fans will be the first to tell you that there’s nothing quite like testing your card-battling prowess against another human being. PvP in the Spire allows you to do just that, allowing you to engage in online battles against your friends (and enemies) in a deckbuilding duel of wits. It’s worth noting that this Slay the Spire mod is incompatible with other character mods, so we recommend disabling them before you go head-to-head with your opponent.

Pokemon Regions

Do you fancy yourself the very best at Slay the Spire, like no one ever was? Then Pokemon Regions is the mod for you. Get ready to embark on a journey to encounter, catch, and battle pocket monsters as you ascend the Spire, with new cards and relics to facilitate your climb. At the time of writing, Pokemon Regions comprises the Kanto Pokedex in Act One, with Johto and Hoenn to be released for later acts in the future. Move over Palworld – there’s a new Pokemon PC game in town.

Googly Eyes

The Spire can be an arduous climb, so you might be looking for a touch of levity to help lighten your step. The Googly Eyes mod does exactly what it says on the tin, replacing every eyeball that appears on every card, character, and enemy with Hobbycraft’s finest. Is it childish? Yes. Is it also one of the best Slay the Spire mods around? Absolutely.

Downfall Expansion

The Downfall mod is essentially an expansion pack to Slay the Spire. It’s a massive mod that adds a whole load of additional content including a new campaign, seven new characters, cards, relics, and more. Downfall is most well-known for its titular Downfall mode, giving players a chance to play as Slay the Spire’s iconic bosses as they fight against the heroes attempting to ascend the Spire.

Super Fast Mode

Self-explanatory, really, but the Super Fast Mode mod lets you speed up your game, so you can blast through the heart in record time. One for the seasoned Slay the Spire players in the audience, this mod can help you power through those animations you’ve likely seen a thousand times before.

Relic Stats

As you approach the harder ascension levels, picking the correct relics in a shop or at the end of a difficult boss battle can set you up for the rest of the game. The Relic Stats mod monitors the effectiveness of each Relic, providing you with a quick snapshot of whether it’s worth adding to your collection. If you want to improve your overall gameplay, Relic Stats is a nice and easy way to gain a small advantage without feeling like you’ve cheated in some way.

Unlock Everything Mod

Arguably the worst part about Slay the Spire is when you decide to purchase the game on another platform. With four playable classes, 20 ascension levels, and hundreds of playable cards to unlock, it’s not exactly a walk in the park when it comes to regaining everything you once had. Fortunately, the UnlockEverythingMod instantly unlocks everything apart from the Steam achievements, making the transition over from mobile or console over to PC practically seamless.

How to install Slay the Spire mods

If you want to play all of these new mods, you’re going to need Mod the Spire, BaseMod, and StSLib to get them working together. While this isn’t a mod, it’s a mod loader, making it possible for mods to work together. Once you have all of these base mods installed, you should be able to run everything on this list.

Now you’ve got the best Slay the Spire mods to hand, you’re ready to ascend the Spire in an entirely different way than before. If these mods just aren’t good enough for you, here are the best roguelike games on PC and the best Steam Deck games to play this year, from Balatro to Cult of the Lamb.
