Documentation

Technical reference for CultTweaker, the Supercharged series, CotL MiniMods and COTL MP Steam.

Documentation

Reference material for every mod in this collection. Each category covers what the mod adds, how to install it, and the exact configuration files it reads.

CultTweaker

The world editor, custom dungeons, player and follower spines, weapons, NPC quests, enemies, structures, and the modding API.

Supercharged Series

Supercharged Tarots and Supercharged Followers: card lists, rally mechanics, class boosts and prestige levels.

CotL MiniMods

Custom structures, follower roles, rituals, commands and the Trial of the Gods difficulty system.

COTL MP Steam

Online two-player co-op over Steam peer-to-peer. In closed testing — notes on hosting, joining and what is synced.

Before you start

Every mod here runs on BepInEx and needs COTL_API. Install those first, then drop the mod folder into BepInEx/plugins.

Questions, bug reports and modding talk all happen in the modding Discord.

Tools

Follower skin builder — convert old COTL JSONLoader skins into the CultTweaker follower form format, author new ones, and preview them on a live skeleton.
MCP server — connect Claude, Cursor or another AI tool directly to these docs, or read them as plain markdown.
