PowerBytes
by JarPish
PowerBytes, a Fabric mod for 1.21.4, gives players magical abilities, a leveling system and a custom combat mode.
What it does
Players gain experience by killing, and leveling raises stats that cover health, damage and defense, along with the abilities they can use. Abilities come from items: a chip or a stamp grants a new ability when used. Combat has its own mode, opened with the left Alt key, where the custom abilities are used against other players.
NPCs spawn in the overworld at custom structures, where players can reach further abilities. Some structures contain custom boss spawners, and clearing them moves a player's progress through the mod forward. The content includes four techniques (Air Knife, Probability, Firework and Barrier) and two stamps (Late and Flower).
PowerBytes is published for Fabric only, with a single version: 0.0.4-alpha for 1.21.4. It needs Fabric API. A server running it needs every connecting player to have it too. The mod is licensed under All rights reserved and is not open source.
Key features
Magical abilities
Players use magic-based abilities to fight and explore, which expand as the character levels up.

A dedicated combat mode, opened with the left Alt key, lets players use the custom abilities in fights against other players.
Leveling and stats

Techniques and stamps

How it compares
Simply PVP is a Fabric combat mod for 1.21.11 – 26.3 with a client and server environment, released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and not open source. Soul Forging is a Fabric mod for 1.20 with a client and server environment, also under All rights reserved and not open source. PowerBytes covers only 1.21.4, so the two mods target different versions.
