I was gonna ask "why you in 3rd chapter and still don't know 3rd circle", but then I remembered about shitty circle book placement and how I had to climb walls of certain fort to reach it early. You can do that too, just search online a bit.
I'm not interested in cheating like that. I'm basically trying to rush main quest stuff now though so I can get 3rd circle, cause 2nd circle is not really cutting it. Hopefully I can find some good spells too, cus ball lightning doesn't look all that impressive either (but if it's raining.... bwahahaha).
Anyway, by chugging a bunch of potions in between the fights, and maybe getting slightly lucky with rng, I made it to 2nd round and getting defeated there was acceptable so I progressed. My ice lances did minimal damage against the first round 2 fight though(reckon I'd need about 20, which is 200 mana more than my max), so there's no way I'd be able to win it. Maybe by using up a whole library of scrolls, but I'd rather save the money and limited items for something essential.
