I am playing as a lvl 19 monk at the moment, and i can tell so far after 3-4 hours of playing, that it is a mixed bag. On one hand, you're really difficult to kill, let alone to take any damage. On the other hand, one can get into situations where you and the enemy swing at each with no hits, and your wizard in your party is out of spells. The only thing left to do is going back and have an 8 hour rest
Can't your wizard have a quick nap while you're duking it out?
