Actually, no, to get the second spell, you had to put on mindflayer ring and go into the swamp, where a new enemy appears. I had to surrender to him so that I could be taken to mindflayer. He actually drops this spell when he wins.
thx a lot cuz these 5 points for skill was actually driving me crazy :3 (also mind me asking but what are these 2 items on your screenshot i just saw them and i never encountered this lamp and WIP version of dildo?)
And i got 100% on all events, but still can't find last spell..
