The first trial is ridiculously hard, in fact. TOO hard to be possible as a first trial, in scale with the other trials. I find the end game boring: No skills to upgrade and very little mana makes casting spells and any variance lacking. Hero becomes weaker than the average run-of-the-mill orc in the game, not even able to pick at any bosses later on. My advice is: make more skills, make experience spendable on increases mana and hero stats. Like this comment if you agree.
