Reversedh Your review makes no sense.
First off, if you rush the game then in 20 minutes the more difficult fight you come to is in fact not a boss, which you would know if you had continued playing past that.
Second, You can avoid combat rape by not letting your health drop below 50%
Third, That fight is super easy even rushing through the game. Assuming you have actually fought through everything one time (not grinding) and remembered to buy potions before hand.
Finally my suggestion to you would be to use M.Burst at the start of the fight, open up with the new ability you get that is AOE to eliminate the smaller enemies and then nuke the mage.. Potion as needed. That is the entire fight. **Important note, did you buy the new spells from your sexy teacher? You can get the money by selling enemy drops very easily. Orcs are weak to wind magic the cheapest spell works quite well **
Also you can't make it further than that in 20 minutes, unless you are somehow hacking the game..
It took me close to an hour to reach the next area, and that was knowing the game well enough to skip past everything. Without doing "ANY" Grinding.
I started a bran new game, encountered him at 20 minutes, and by 25 mins was over and done with. Including the time for all the cutscenes...
