Are you kidding us?
You need 4 triggers per player, that is 48 players to make the system MPI
Dude rework this asap if you HOPE of getting this aproved.
MUI spells/systems are a minimum now, use hashtables or indexing.
The usage of this system is doubtable,because of 1 simple thing, making custom attack is even easier than you are doing here.
I attached an example showing how you can make a custom attack ability, then you can detect it fire off and use it on any way you want to use it, meaning attaching whatever your heart desires.
ALSO the one i attached is activated via Right Click, look inside how i did that, it is easy.
