I honestly suggest you try challenging yourself to make a virgin playthrough without cheating, since you stated that's possible. If it is, it's probably going to take hours and hours of grinding the first two enemies in the game before you even unlock the dogs. Let me know how long it takes you.
I finished the challenging. It took me less than 2 hours for a virgin walkthrough. I attached the save. The difference between you and me is only that I know the game mechanics better than you. So after you spend some time exploring and experimenting (I think this is needed for a game right? It's not a AV or erotic novel after all) and knows the mechanics better, you will easily achieve this.
I just think it's unfair to say a game is not balanced before you know its mechanics. It's just like playing Starcraft2 you use Terran Marines to counter Protoss Colossi and lose all your marines and comment that the game is not balanced.
I just want to get back to the fun stuff
To me, one of the fun parts is to learn, to explore, and to find a best solution. Isn't this the difference between a game and an adult video? Learn about the mechanics, the items and skills and think about how to use them wisely. For example, if she receives too many pleasure or arousal, buy the Anesthetic to lower the sensitivity. If you want to see rape scene while still keep virgin, equip the Vibrator. If you feel it's too hard to resist a rape attempt, use items or skills to manage the sexual desires.
Looks like we accidentially changed our topic to boss fight, but it wasnt actually my main problem. Under right (right = incredible luck) circumstances I'm able to kill it in 3-6 turns (literally had 16k crit damage from normal attack after using damage buff skill).
My main problem is estus/heat, which not only triggers almost every turn, but also stuns MC. And its trigger change rn is not affected by corruption, lewdness, arrousal or pleasure, but rather on which passives MC has and your luck. And playing this game normal means you will have tons of passives (which I don't find bad). Actually, maybe it depends on lust for *enemy type*, but that doesnt help, since you cant lower that paramets and boss is dog enemy. And you have at least 2 locations with dogs meaning you have double amount of its lust.
This is my problem. Stunlock which you can't control is bad. Stunlock which depends on MC current state (corruption, lewdness, arrousal or pleasure), like, for example, sex, is good, since in good condition escape rate is 100%.
I see. Then that's because the MC already acquired the fetish "Bitch in Heat". In my walk through, I kept the sexual desire and lip / butt sensitivity low so that she wouldn't frequently fully turned on when fighting dogs. That controlled her lust for bestial and avoided getting that fetish too soon. You can see in my save, I only boost the attacking power to 1000+ and can defeat the boss within 3 minutes by just using Mind Pills, Goddess bless, Goddess fury and Hard hit. But even if the MC had that fetish, it's still possible to win, just takes more time and more powerups to raise her attacking power. To do so, you need to combine the use of Mint and Goddess bless to remove the estrus state so that you can use the Hard Hit, or even plain attack. Estrus state reduces hit rate. This boss doesn't recover unless you let it rape the MC and the MC squirts. So just be patient if the MC has that fetish. A "bitch in heat" is of course weak to male dogs and it makes sense to me she needs additional effort to win the fight.
If not in the boss fight, bring some banshee rune or other items, so that you can enjoy the rape scenes as much as you want and if you get bored and want to leave, wait for a chance to use those items to instantly kill a regular monster. Vibrators also helps to instantly kill a regular monster. And similarly, if want to remove the "in heat" state, mint or goddess bless would help.
To me, the 0.8a is well balanced. Every new mechanics had been thoroughly tested by me. There's of course some places to improve in the next update, but the game mechanics have no big problem.
