Multiple Unit Instance-able?
means you have can multiple units use the same spell without it bugging (due to overwritten variables and such)
MPI is multiple player
so you can have 2 different units owned by 2 different players use it without bugging, (if its not MUI then, 2 units owned by the same player would bug)
if something is MUI, its also MPI
do local variables leak? sorry im new.
