Exp problem

I used a trigger ability and killed enemy unit.
The problem is I don't receive any Exp.
How can this be fix?

Well, you can't do it still using the "Kill" command. That is the danger of doing stuff like that trough triggers, it wierds out XP and gold and the like. One thing that you can do though, is create a dummy unit that has some direct damage ability that can deal 99999 (or some other rediculously huge number) and have it use that spell on the unit that you want to kill.

Tried that.
Still can't get the XP.
