I haven't figured out how it's different from it's first form. Anyone know?
I missed the first form, so no clue.
Also I'd take Assassin over wizard if you're going all-out. Swift Hands is invaluable for a character with such horrifically bad attack damage.
I agree with you on that one (and the assassin's much better placed to use the bonus mana and leverage level-ups to take advantage of remaxing your mana, I reckon) but the wizard build's still placed to quite reliably thwack hard dungeons. For the wizard, on the plus side, you don't really *have* to prep Mystera(+fireball magnet), though Flames is obviously nice to have.
