Increase variable on killing monster via enemy notetag

[RetailDrone7576]

I need a plugin that lets me give a monster a notetag that will increase a variable by x amount whenever the monster is killed. I want it to be a note tag so I don't have to event for every troop encounter, I'm using yanfly's enemy swap plugin and I want each monster to be able to increase the variable by a different amount so being able to use a notetag instead of control variables would be much simpler and easier for me in the long run

why not control variable by x when killing the monster?
unless you want something specific, you need to give more information.
because the info like that is to low.
