For those that didn’t grow up modding Warcraft III: a “buff” is some lasting effect that is applied to a unit, such as it being stunned or on fire. Needless to say, Exon has lasting effects too. It’s not all impact-and-forget; mechs need to get stunned and corroded and all sorts of other things I haven’t thought of yet.
How hard can it be? You just stick the thing in a list and count down the timer until you turn it off… right?
