This is the Internet, silly.
And? It is "her"! A fact that I let everyone know as soon as they call me "him"

Anyway, back to the point, yes I grabbed Tejon's code for Oblivion XP's killing script. It works beautifully, but Ob XP doesn't address the issue at hand. My summoned creatures will happily go after the all the enemies - summoner and critters alike. However I still find that the summoner likes to go after my summoned critters instead of "me". In fact, I'll stand right in front of him and he'll be trying to push "me" out of the way! And I find it hard to believe that my summoned creatures have better stats than I do. At the point in the game where I am now, as soon as I get a shot in at the summoner, he's dead, so there's no opportunity for him to target my PC.
I needed Tejon's script because Oblivion XP wasn't awarding points properly when you killed a summoner that had active summoned creatures. That has been fixed. So the code knows who your target is and knows if that target has summoned creatures. If you want to see the code, let me know and I'll post it here or in a pm.
