@ I know I can be a pain in the ■■■ but one last question - As I got I think everything working as I wanted 
… If my abilities are previewed od some chracter class - BUT in the execution I use zero casts, zero animations that are one skeleton specific (i dont run animations at all… just gameplay tags) and only call events and interfaces, and ask for variables on interfaces… this ability should work on any character that use the interface… or even pawn… or object as far as it matters right? So an ability made for human will work on a dragon, or magic item - as long as it implements interfaces, or has proper component that the ability use?
