I too would like a way to do continue battling. I got a lv200 character with a 50% crit rate and literally one shot most battles with a crit. the max level sofia battle literally takes me 2 crits with demon layer. Guess thats what i get for having no life lmao.
Lmao i got bored so i started trying to beat the last sofia fight in 1 attack and thought i could do it with enough crit rate and damage. (Close to impossible btw, 2000 damage in 1 attack, still cant get it lmao) I put on 3 enlightenment runes the exp cock ring and got the blessing of experience as well as all perks to boost exp. If u want ill actually give u a guide lmao.
Well for early levels its probably better to do Sofia's first stage. The best way to do this is to just put her to sleep and spam demon layer. Doing this u can beat her pretty easily. Remember to always put on enlightenment runes and getting a blessing too.
Once you are confident that you can beat her that way pretty easily, buy and put on the cock ring that boosts exp. Keep in mind this is a very debilitating item but it doubles your exp gains. As long as you keep putting her to sleep as soon as possible, you should manage to beat her and if need be u can also restrain her if u need more time to beat her. Restrain and sleep together keep her occupied for like 5 turns usually. Dont worry about healing as you get healed everytime yyou level up.
Now for the big boy levels you're gonna have to start doing Sofia's last fight. Keep in mind its better if you've beaten her last fight normally first cause its already pretty hard.
The first turn its always better to buff your technique as that allows you to dodge a lot of her attacks and lets you hit her with demon layer.
Now my build is a max crit rate and damage build which i consider would probably be the strongest possible in game tbh. With all the perks for crit rate you can achieve like 50% crit rate and almost x4 crit damage.
So basically for the second turn of the fight buff your crit rate and got to town with demon layer from the next turns. Once you're strong enough the method becomes a lot more consistent. Kotones lover perk is pretty useful to just ignore her trance stuff otherwise u can use items too.
Well thats about it tbh hope it helps lol.
