Skillheim!

Each skill grows through use rather than through a separate menu. Sprinting gradually increases base movement speed, leaping raises jump height, time spent in water increases swim speed, and crouching improves stealth. Punching mobs raises unarmed damage, and the mod starts that gain at a 10x XP multiplier so early progress comes quickly. Spear combat is also part of the system, so players who keep stabbing deal more damage over time.

The design follows a simple philosophy inspired by Valheim: players run faster, jump higher and hit harder by doing those actions. Progress is not a separate task, which fits the mod into vanilla survival, where time spent surviving, fighting and exploring is what builds the character. Skillheim! requires Fabric API and runs on Fabric 1.20.1 only. It is published with the environment set to client and server, so the server and every player need it.
