=============================
The last AH I played was Druid/Wizard. He had a few fun combos, including Feeblemind + Quickened Ray of Stupid for quick Will save kills. He also had a 1600lb (the average, I believe) grizzly with a pair of Slippers of Spider Climb that he likes to Animal Growth so that it can squish things when it lands on them.
You can probably refine this, of course. I am AFB and working from memory here.
