Just to experiment, I decided to try for the "control" path, despite having given Keawe both a corrupt crystal and corrupted wood. I managed to defeat all of the tentacles. The next day, when visiting the church I have the same options that I would normally get if I was on the "avoided the succubus at the start of the game" path and had agreed to corrupt the church. Is this how it's supposed to be (since this is a combo I'd never tried before)? I've attached a save in case it's a bug.
Also with this save I've tried speaking with Vivianne (which I'm supposed to do regarding the tentacle critter I captured during the major battle the previous night) but I get no option to discuss the captured tentacle beastie.
I think I may have incorrectly switched on the flag for corrupting the Church, there. Good catch.
Currently, Vivianne doesn't have any implemented responses regarding the captured tentacle. That will change during the course of this month.
Displaying the tenta-tail in the character stats isn't implemented yet.
Yes, Keawe would have four critters in her with her double wombs.
For losing to the tentacles and accepting their gifts, yes, you now SHOULD have the option to corrupt the Church -- because you have to find some way to gain acceptance for the tentacle creatures that now live at your house.
Technically, you haven't "solved" your tentacle attraction yet, although I should word the quest a bit better. The final solution for that -- for the "submit to tentacles" path, that is -- will involve getting the town of Tyrmidon to accept tentacles, rather than being afraid of them, banning sex with them, etc. For the "control" path it's different, and for the path where you've killed the tentacles instead of trying to control them, it'll involve yet another solution.
Yes, currently the Huntress is imbalanced. I want to eventually come back and "fix" that class -- giving it more content (like the sorceress and the alchemist both have), giving it more potential weapons to use, and higher skill in using them. It's on my (rather lengthy, at this point) todo list.
