Aura onDamaged Mechanic doesn't work

  Id: DIAMOND_SWORD
  Data: 0
  Display: "&7&lTest Sword"
  Lore:
  - "&5&oTest Sword"
  Skills:
  - damage{a=4;ia=false;pi=true;pkb=true;element=DAMAGES} @self ~onUse```

Then i do /mm test cast AuraDamages

```AuraDamages:
  Skills:
  - message{m="debug"} @self
  - onDamaged{auraName=TestAura;damageMods="DAMAGES 4,DAMAGEB 1.2";i=1;d=20;refreshDuration=true} @self```

And i always take 4 damages, not 16 as it should be...
