COI Client is a client-side Minecraft Fabric mod that connects you to servers running the Circle of Imagination plugin. It delivers a rich in-game experience — bind up to 6 abilities to hotkeys, spin up an interactive ability wheel, watch cooldown timers on a configurable HUD, and see server-triggered visual effects render directly on your screen.Documentation Index
