Sooo many Rogues...
My Melee Wizard Extraordinaire!
Playing on Hard, he can actually take a fair bit of abuse before needing to rest, but I usually have to rest due to the per rest abilities and spells being spent first, so the health aspect doesn't really impact me. While he can't do primary tank duty, he can usually tie up one or two enemies if necessary. This is with offensive spells only, he can be far better defensively with a defensive spell or two.
