So, I finally settled on a class for my character, and have started to explore the city a bit. My main character is a Kitsune Sage Sorcerer, and I hired an Oread Primal Druid as a mercenary (she has a pet smilodon). In kingmaker I usually focused on spell focus feats for my casters, but due to the number of demons out there, I am instead trying to take spell penetration ASAP. They still often have trouble with demons, but slightly less trouble now. My first move after returning to the city was going to the market square. I had a lot of trouble there with the various enemies, especially the shadows, and shadow demon. After finishing most things available at the square I returned to the tavern and had to defend it from a demon assault. That was a fun battle, in which Lann scored a key critical hit against the main enemy, the minotaur, for 40 damage! After this I fought some enemies in various miscellaneous places and things weren't too bad until I returned to the market square to take care of some unfinished business. I was quite surprised to find that new enemies had spawned there. The hardest new enemy was a Nabassu; nasty thing, with its level draining and mass paralysis, not to mention the ghoul entourage it had. I also summoned a Vrock and had to fight it too, which wasn't too bad I guess.
I do wonder if I should be paying any attention to the mythic path stuff, though. so far I have encountered several mythic path choices in dialogs and am trying to follow the non evil ones, just to keep my options open.
This is a really hard game but it has been fun so far, if a bit frustrating at times...
