ModConfig

A framework for easy mod configuration

in the core ModConfig by PiPiFanDev is a universal mod configuration framework Slay the Spire 2inserting the “mods” tab into the game settings screen. This mod is highly recommended for many mods on Nexus Mods, at least for full functionality. When other mods are installed, their configuration items are added to the “mods” tab, allowing full control over the configuration of each from the in-game menu, as long as the other mods support ModsConfig, ie.

Even though it's a simple tool with no custom game mods, ModConfig is a great way to manage your custom settings and preferences on the fly. This is especially useful if you are using multiple other mods at once, due to its static location for all mod configuration settings.

BetterSpire2

Extensive quality of life adjustments

BetterSpire2 is a light quality mod by JDR that doesn't significantly change the way the game plays, but makes the gaming experience a bit smoother. While most mods are currently single player only, BetterSpire2 has the advantage of being multiplayer safe and has two versions: full and lite. The full version includes the ability to hold R to restart a run from the beginning, double-tap R to reload the last save and start the fight from the beginning, kick players out of a multiplayer session, difficulty scaling options, and auto-confirm discard/keep selections.

Both versions include an incoming damage counter that automatically calculates the damage you take after blocks and damage reduction, multi-hit totals, expected HP that will see your HP after the damage is calculated, a manual teammate viewer, splash screen skipping, the ability to hide multiplayer map artwork, and instant fast mode, which is faster animations.

These settings can be toggled individually from the in-game menu, so you can better tailor your gaming experience to your needs. I find the damage calculation to be most useful for single player and sometimes it can be a bit overwhelming to calculate all the incoming and outgoing damage between summoning, relic modifiers and any block generation you may have. It just makes it a little easier so you can focus on the strategic aspect over the calculations needed to play optimally. The multiplayer options are also a nice addition, as the base game doesn't include any way to remove players or display their hands to help coordinate strategies.

UnifiedSavePath

It keeps all your savings in one place

It will show a menu where you can save and exit the run. Other options are: Continue, Settings, Overview and Give Up.

Under normal circumstances, Slay the Spire 2 modded saves are placed in a separate directory, meaning that any progress you make in the game with mods will not carry over to any non-modded save files you may have. Use UnifiedSavePath by Jiesi Luo alleviates this problem by merging both storage paths. All character unlocks, epoch progression, and run history are shared across both modded and unmodded saves.

The unified save path does not otherwise change the game experience, and no other content is changed during installation; you get only one set of locations for all your files.

Route design

It helps guide your way up the tower

Do you ever feel like you can't decide which way to go during a run? Route design by Jiajie Chen might just be the tool you're looking for! It will suggest the optimal route on the map and highlight it, showing you the best course of action based on your preferences. In total, there are two types of path designs: safe and aggressive. A safe path minimizes encounters and prioritizes safety by emphasizing rest stops, treasure chests, and shops. In contrast, the aggressive path design favors monsters, elites, and unknown rooms, giving you plenty of opportunities for card rewards.

While you can technically use the mod without it, ModConfig is recommended in tandem with Route Suggest as it allows the mod to appear in the game's mod menu for easy orientation and configuration. Without it, you'll have to edit the JSON configuration file manually. These configuration settings allow you to change the color of the paths presented and change the rating weight of each room type, giving you a more customizable experience.

Quick reboot

Quickly restart battles or events

The defect is equal to the architect. The text reads: Are you back? Didn't I tear you apart?

Another handy mod by Jiesi Luo, Fast reboot, is as simple as it sounds. Pressing a single button (F5) will start the current event or battle from the beginning and restore your deck, HP, and relics to the state you entered the room in. It's smooth to use in practice too, with a simple transition from screen to black when you reload a file.

Thanks to its use Slay the Spire 2Thanks to its own native autosave system, there's no additional risk of corrupting your save files, although the loader only works when active – it won't work when you're in the menus or on the map screen. There are no compatibility issues with any other mods, although the mod maker specifically suggests a UnifiedSavePath to ensure that modified saves are properly accounted for.

It's just a great time saver because it cuts out the save and exit button presses that normally accompany room restarts.

Remove multiplayer limit

Play the game with up to 16 friends

Sorting of StS characters 2 — Kill a series of Spire 2 characters

Slay the Spire 2The inclusion of multiplayer is perhaps the biggest change from the first game, but its four-player limit can be limiting for players with a large contingent of friends who also play the game. That's the place Remove multiplayer player Limit by Rain_G is coming. A single multiplayer lobby can hold up to 16 players when using this mod, although lobbies with more than eight players may suffer from some rendering and UI issues.

In addition to adjusting the number of players that can join the lobby, the mod also makes visual adjustments to the game, such as changing the seating arrangement at the campfire to prevent player models from overlapping. These visual changes are also extended to shops and relics, avoiding visual clutter that could prevent access or recognition of any elements on the screen.

How to use Slay the Spire 2 console commands

If you want to experiment with some fun stuff in Slay the Spire 2, here's how to enable cheats and other console commands.

Watchman

Let the Guardian unleash his wrath on new enemies

Watchman mod by lamali porting the character “The Watcher” from Kill the tower to Slay the Spire 2. If you missed The Watcher's unique mechanics of rage, calm, and divinity, it returns in full force, unchanged from the original iteration. All 83 observer cards from the first game are included, as well as eight observer-specific relics and 10 related colorless cards and related abilities.

Perhaps most impressively, The Watcher mod also features the selection screen animation, hit and idle animations from the first game, and stance VFX and SFX. The mod is really well done and the observer doesn't feel out of place at all, even with the new mechanics, events and fights.

More card rewards

More options for building your deck

When playing a deckbuilding game in Early Access, a big part of the experience is testing out new strategies and synergies. With the large number of characters present in the game and the huge collection of cards to choose from, getting a good deck to play with and test can feel more like an exercise in patience than anything else.

More card rewards by Emo Used HM01 makes things a little easier by changing the card's base reward number from three to five. No other modifications to the gameplay experience have been made through this mod; its overall usefulness is limited, but seeing more cards is definitely a big boon for testing and balancing purposes.
