ManasJS
by iamurubonz
ManasJS adds KubeJS scripting to ManasCore, the shared library behind mods such as Tensura, so server scripts can work with its skills and races.
What it does
Server scripts in the kubejs/server folder can react to skill and race events, including skill obtainment, removal and activation, and can change cooldowns, damage and race behavior. A script can also add, remove or evolve skills and set races directly, and can override mastery cooldowns. ManasJS needs ManasCore on NeoForge 1.21.1, and it is server-side only, so players join without installing it. The Apache License 2.0 covers the code, which is not open source.
Key features
Skill and race events
Scripts can listen for events when a skill is obtained, removed or activated, and respond on the server.
Programmatic skill control
Scripts can add, remove and evolve skills, and set a player's race, without manual commands.
Cooldown and damage changes
Scripts can change skill cooldowns, damage values, and mastery cooldowns for a pack.
