Radium Client Mod (1.21.10, 1.21.1) – Free Ghost Client for DonutSMP

Available for:Fabric

For players who thrive on anarchy servers and high-stakes PvP, Radium Client Mod delivers a comprehensive toolkit that goes far beyond a typical utility mod. Built around combat macros, ESP modules, and server-specific automation, it turns Minecraft into a fully controllable battlefield — especially on DonutSMP and semi-anarchy servers where every advantage counts. Whether you are farming resources, hunting bases, or surviving crystal PvP, Radium bundles dozens of modules into a single Fabric-based client.

Key Features
