Player Abilities

Abilities are grouped into categories and can be selected in an Ability Wheel opened with the Z key by default, scrolled through by page, and cycled with a key. The selected ability appears on the HUD, and an ability book screen lists the abilities a player can access. Using an active ability may require standing still, and a progress bar counts down during charge-up, channeling or wind-up, with the effect running once it completes.

Each ability has a cooldown and optional requirements, such as a number of kills or damage taken, that a player has to satisfy before reusing it. Abilities can scale effects, cooldowns and wind-up times with their level, and can apply standard potion effects or custom ongoing behavior written by the developer. A cooldown reduction attribute from gear can shorten those times. Levels, cooldowns and requirements can be tuned through configuration or datapacks, with more than 10 configuration options.

The mod works on Forge and NeoForge for 1.20.1 and 1.21.1, and the environment is client and server, so both the server and every player need it. The license is All rights reserved, and the mod is not open source. Its framework also includes an API for developers who want to add their own abilities. Players who want to try abilities without building them can install a companion mod that implements them.
