Who can say here you can hypnotize others yourself? It seems that the hypnotist taught hypnosis, but I don’t know who to use. And as I understand it, Kira can also hypnotize you or not? If so, how to continue relations with her. I killed a dragoon, talked to her and that’s it. Then nothing happens. And what do I need to do to continue the vampire quests. I found a vampire girl in a solina and made her a slave. And then nothing happens.
The content for the hypnotist lessons isn't in the game yet, sorry. Kira can also hypnotize you. You must not kill the dragoon, but capture it, instead (Kira gives you an item to use on it once it is weak), if you want to continue her story. The vampire stuff and other content will also need you to advance through the chapters, at times. If you don't get any new content after trying for a couple of days, you can probably wait until the next chapter, before going back.
So it seems like if I favor the Adventurer's Guild in the Lidless Eye quest, I'm stuck at Novice rank in the Mage's Guild due to an inability to get new mage quests. Is this intentional, or will there be additional quests later?
There will be more quests. I am considering some more consequences to being in both guilds, but I don't want to flat out lock up one of the paths (unless someone always favors one of the two sides).
How to become a Sonya pet? I completed her quest to find a girl on the second floor, and then she just says work and that's it. What you need to do next. And one more question, is there a continuation of the story of the vampire doctor? Or is there only 2 scenes?
Did you complete the quest successfully (and got hypnotized together with her)? If so, that's the end of the path. You'll get some small changes in the bunnygirl job and stripper job by having the Bimbo trait, by having progressed far enough on this path, and (in a couple of instances) by the exhibitionist trait and your breast size, so you might want to do a “before/after” run, to enjoy the variations.
Sonya has a different path, but you must be stuck with Marintas's pendant (to get it, you must try and fail to escape from the Outcasts, during a quest for the adventurers guild, to escort a merchant). The pendant hypnotizes Erica whenever she hears a trigger word.
