Weapon skills don't work

The skill works fine in /test cast But in weapons it doesn't work, even if it is ta message, but it used to work before I tried removing plugins/resourcepack/datapacks and changing game version, and trying from all versions I can on survival/creative and it didn't work too

Am running on 1.21.1 + MythicMobs-5.7.2-SNAPSHOT.jar + MythicCrucible-2.1.0-SNAPSHOT.jar

Here is the weapon and skill : [Legacy attachment omitted]

How it suppose to look like on cast : [Legacy attachment omitted]
