i cant see to start day 20 because the ass implants is missing, i presume ya have to do something on day 19 to get them as there books that gives the code to spray but idk what i missing
well... i did correctly all the potions for the adventurers but if by defeating her ya mean to do something with her at the end, then no
i have the feeling the books ya find below when ya turn into a goblin tells a hint on defeating her, but i clueless on what else missing
i used the spray on her before the main character gets on a stool and after, but i feel like i should done something to acctualy affect her to defeat her
