by ikeepcalm

COI Client is the client-side half of a Lord Mysteries power system, with an ability bar, sanity effects and hotkey-based casting for Fabric players.

What it does

The mod handles the ability bar, casting inputs and the screen effects tied to sanity, while the server sends the state it needs. The client draws everything, so cooldowns and player transformations run locally and keep load off the server. It works with the Circle Imagination plugin, which carries the server half of the system.

Players set up Fabric with its API for Minecraft 26.1.2, then add the COI Client jar to the mods folder. Files are published for 26.1.2 and 26.2 on Fabric, with version 1.2.3 for 26.2 as the latest file from 2026-10-03. Only the client needs the mod, and it is released under All rights reserved, so the code is not public under an open license.

Key features

  1. Ability bar

    Six slots bound from Z through N show abilities in a bar that reflects cooldowns and casting, unlike the vanilla display.

  2. Ability wheel

    Holding G opens a radial menu, while holding Left Alt and drawing a shape with the mouse casts ritual spells.

  3. Sanity bar and effects

    A sanity bar follows the madness level, and screen effects such as blood rain, frost, heartbeat pulse, tunnel vision and VHS static appear as sanity drops.

  4. Player transformations

    The player model is replaced by animated pathway forms such as the Fool, Sun and Tyrant, rendered on the client.

The client-side half of the COI server plugin (Lord of The Mysteries power system, recreated in Minecraft), built for Fabric.
