Some key issues I want to clear up:
- When using Super Munchkin with two classes, you get the advantages and disadvantages of both classes. You can't avoid the Wizard oriented Bad Stuff because that's a disadvantage of being a Wizard. If he wanted to remain a Wizard, he needed to discard his Warrior Class.
- Once he failed to Run Away, he could not discard the Warrior Class (and lose the disadvantages of being a Wizard) until he resolved the failed Run Away roll. So, the Warrior discard would have to occur before the roll.
