Thanks for the replies...
@Straw_Man: I was seriously tempted to go with Dread Necro, but the rrebuking would be weak.... I also thought in Sacred Exorcist...
@Omen of Peace: thanks for the tips....starting level 1
@Eldariel: I don't know if the DM would allow Nar Demonbinder to qualify for UM.... he might think it's too gamebreaking (he took half an hour to understand how Augmented Casting works.... and he said Chameleon is uber powerful - it's his first time DM'ing as well). I will show him and see what happens...
EDIT: in case of going the Nar Demonbinder route, here's the build:

Progression: Wiz 7/Nar 1/UM 6/AM 1/UM +3/AM+1/UM+1
