I enjoyed it highly , but don't recommend full magic user to anyone looking for a challenge , when you get to the part where you can make your own spells , you can make some ghastly 50 ft radius bomb for clearing tunnels. and rooms in seconds.
I mostly found heart with a sneaky archer/assassin. Hand to hand main non ranged weapon , nothing like sneaking up behind someone and punching them in the back of the head for 6x damage (hand to hand gets huge sneak attack bonuses)
