fix: Buff FX not playing and general BuffComponent improvements (#1296)
* fix: Buff FX not playing

Fixes an issue where buff effects would not play at all.

Tested that frakjaw and maelstrom dagger now play their respective effects when you are effected by them

fix: buffs general improvements

add new arguments

* Remove duplicated code

* fix times and remove buff
