Corz Client

Schematic projections and a crystal PvP suite in one client.

• Loader: Fabric
• Minecraft 1.21.11
• Latest: v1.0.0

Overview

Corz pairs two things you don't usually see together: a building toolkit and a PvP kit. Load a schematic and it shows up as a hologram in the world, with ghost blocks telling you what goes where. Then flip to the combat side for crystal fights.

Features

• Schematic projections: Load a build and see it as a hologram in the world
• Ghost block guides: Shows the next block to place, layer by layer
• Crystal PvP suite: Placement and breaking tuned for fast fights
• Hitbox visuals: Clearer hitboxes so you know what you're hitting
• Keybind macros: Bind module combos to a single key

How to install Corz Client

1. Download Corz Client v1.0.0.
