New Characters

The Glutton

GluttonMod adds a new character for Slay The Spire, The Glutton. It has 75 cards and 11 relics.

The Glutton is a insatiable being, eternally wandering the spire in search of its next meal. It specializes in its own suffering, burdened by cards that afflict the user with pain and injury, as well as those that greatly benefit from such. The Glutton has a limited number of defensive abilities compared to other classes, but makes up for it with a greater ability to heal and raise its own Maximum HP.

The Glutton has themes of self-inflicted damage, exhausting cards, self-inflicted debuffs, as well as using gold as a resource in combat.

The Sage

A mechanic who studied about the cult of a blue bird. She learned flying a carpet and brewing potions in order to stop its rise.

Main Themes of this character are the ability to fly (almost like Byrds do, just on a carpet) and the ability to brew potions over time. Also adds potions, relics and an event to the game. Can be played in ENG and DEU because this is made by two Germans.


Adds Yuri into the game, featuring 50+ new cards, 8 relics and a few nasty surprises. May contain disturbing content, which can be turned off in the settings.

The Slimebound

Adds a new playable enemy character: The Slimebound.

The Slimebound adds over 90 cards (not all in its card pool), 8 new character-specific Relics, 1 new Potion, and has a couple secrets to discover. As a slime monster, split into smaller slimes with their own attacks, goop down enemies with a Slimed mechanic, keep enemies debuffed with Licks, and more.

The Slimebound attempts to stay within the bounds of vanilla STS character design while still pushing new mechanics.

The Jester

The Jester adds a new character with a starter relic who uses all cards in the game, including those from other mods you may have installed. A good character when you want a little chaos, chaos.

The Clockwork

ClockworkMod adds a new character for Slay The Spire, The Clockwork. The completed version will have 81 cards and 13 relics.

The Clockwork is a curious being, obsessed with upgrading its own body in any manner that it can. It is a being of momentum, starting weak, but gaining power over the course of a fight, and over the course of its ascent of the Spire. The Clockwork possesses a number of cards that permanently improve its ability to fight, if you can find the time in combat to safely do so.

The Clockwork has themes of making its own cards during combat (temporarily or permanently), drawing cards, giving itself breathing room to setup, as well as permanently acquiring relics during combat.

The Perplexing (Playable Snecko)

Adds a playable Snecko to the game, who must contend with random cards AND random costs, but can manipulate the randomness to lean it into the Snecko's favor.

DISCLAIMER - This is a one-day meme mod. If anyone is interested in continuing it, I leave it open.

The Administrix

The Administrix, the lich princess of the rising sun, is inspired by Toyosatomimi no Miko (豊聡耳 神子), a character from the Touhou Project series. Her design goals focus on consistency and coherency, with decently reliable representation and support for multiple interwoven deck archetypes. Themes include duality, synergy, and deck manipulation: key mechanics include cards with effects on both drawing and discarding them, Artifact to grasp onto transient power or brush off toxic side-effects, and a manipulable duo of card fuel in Yin and Yang.

Currently has 70/80 cards, 4/10 relics, and 1/2 potions completed.
