With the endless stream of replayability and new content in Slay the Spire, it's nearly impossible to find the game boring or tedious. However, new or experienced players may find the content lacking or the user interface difficult to learn. Should this be the case, there are a few ways to improve it and many other parts of the game with a few mods.

Despite Slay the Spire's almost-unknown modding community, there are numerous mods out there that make the game just a bit better, larger in terms of content, or even more varied in character selection. The top-tier mods are determined by the amount of content, replayability potential, and how well they fit with the base game.

Updated on March 20, 2024, by Ritwik Mitra: Slay the Spire is one of the best deckbuilding roguelikes players can get their hands on. This indie hit features a simple premise along with a tantalizing gameplay loop that leaves fans wanting more with each run, learning how the game works as they die to a tough threat over and over again. It may seem like a challenge that's too insurmountable to overcome, but there's no way to describe the joy that players feel when they finally conquer the very top of this Spire after numerous failed attempts.

The floors of the Spire that players traverse can feel rather samey after a point, so it's easy to see why some players would prefer a mod that changes things up somewhat. The Spire Biomes mod is perfect for players who find the repetition to be a bit too grating after spending a lot of hours in this game.

Floors are structured differently and are a lot more complex now than most people would expect. This makes the traversal of these zones more harrowing and interesting for players who may be getting bored of playing through the same thing over and over again.

Terraria is another indie game on the same level as Slay the Spire in terms of popularity. This title continues to receive regular updates from its developers, making it clear why a game many people dismissed as a 2D version of Minecraft has such a loyal and passionate fanbase willing to defend each and every facet of this unique survival game.

Fans of Terraria can channel some aspects of this tile in a mod for Slay the Spire that serves as the perfect crossover between both games, even if it may be an unofficial one. From relics and potions to the very music used in the game itself, this bundle is a must-have for players who want something different from Slay the Spire after investing a ton of hours into the vanilla experience.

Players have to choose from one of several characters before they decide to make their way through the grueling Spire. Every floor is a test of skill and patience, so it's easy to see why most players would prefer to use a character that they're comfortable with to reach the top. However, while it's find to rely on a character's abilities that players are familiar with, experimenting with other characters is a tried and tested way to keep things fresh and engaging in the long run.

This is why there are so many mods for Slay the Spire that add custom characters with unique decks of their own. Sometimes, modders go the extra mile and add original characters to maintain a certain level of immersion, making the Packmaster an easy recommendation for players who are sick and tired of the vanilla characters. This unique character is pretty fun to control, featuring a new twist on the existing formula by encouraging players to try out new packs and experiment to enjoy an optimal fit.

Sometimes, the mods that players love the most are the simplest ones that don't change things in a major way and end up being rather unintrusive yet helpful. These kinds of mods are perfect for players who want to preserve the vanilla experience with a few improvements that don't change the core gameplay loop of the title too much.

This is why something as simple as the Colored Map mod can make things so much more visually exciting without making too many major changes. The map in Slay the Spire is something that players will be looking at a lot, and it can look a bit drab at times. With this mod, there's just a bit more character added to the game, which is welcomed for obvious reasons.

One of the more popular mods for Slay the Spire includes custom heroes with their very own decks that completely change the way players approach a battle. That being said, a lot of these custom characters aren't all that balanced, leading to the game's difficulty being all over the place if players choose one of these characters.

The Hermit is one such custom character that players can have a great time with once they adjust to the deck this hero uses. It's a novel way to play the game and changes how players approach most combat encounters, which is always welcome.

Given the nature of this game as a roguelike, it's easy to see why people will end up dying a lot in Slay the Spire. The game over screen is something players should anticipate, and only the best players can hope to conquer the Spire after repeated playthroughs that help them optimize their playstyle and figure out the best course of action that can be taken to fight against the many tough enemies standing in their way.

Restarting a run the first time around feels pretty normal, but players may tire of this process if they just want to jump into another run with their selected character instead of going through the motions over and over again. This mod adds numerous quick restart buttons that can make things easier for the player, letting them optimize the time they spend with the game instead of wasting it.

One of the most annoying things about using mods in any mainstream video game is the fact that the game disables mods if players take this particular route. While this is an understandable course of action to take, it still causes a ton of frustration from the player's end.

This is where the Achievement Enabler mod comes into the picture. True to its name, it lets Slay the Spire players enjoy the benefits of achievements even after they use mods in the game!

Enemies get many buffs and debuffs in Slay the Spire, making it important to switch strategies on the fly depending on these effects. However, as players download more and more complex mods, it can be hard to differentiate between the two.

The Colored Powertips mod takes care of this issue by adding green color to buffs and red for debuffs. It might seem like a simple mod, but players who have too many mods will find the gameplay to be way less strenuous once they have a clear idea about the effects on a particular enemy.

There are a lot of character mods out there for Slay The Spire, and each one fulfills a distinct purpose in relation to the base game. However, only a few take advantage of the curse mechanic. This group of cards clogs up unfortunate players' decks and gives negative debuffs, making the game more difficult.

The character mod for The Cursed adds a character that takes advantage of this, as well as a whole new set of relics and cards to accompany him. Not only is the character well-balanced but the art and polish are also phenomenal.

There are many Slay the Spire mods dedicated to recreating characters from other games in the setting of this card battler roguelike. The prime topic of these is usually Touhou, a bullet-hell arcade game, and The Servant takes heavy inspiration from this.

Some shy away from trying the mod based on its topic. However, The Servant busts through any preconceptions of what the genre is about. It creates an extremely compelling character, both thematically and design-wise.
