yes , i beat her with 3 100Tp moves , then when the 2nd fight starts. And i cant win here at all and after i am defeated , she slashes me few times & i die .Thus get GAME OVER. ( i have done it 3 times already but no luck )
In
that case, let me do a bit of digging to see what hidden requirements are in the event's code.
So, this is funny: If you somehow managed to beat the second form? You get a Game Over.
It looks like there's a check for a variable that must be equal or greater than 10 when you
do lose to her. If it's smaller than that, Deelo gets a Game Over after a cutscene that shows the text "Because of the Princess Knight's efforts, Deelo's treachery came to an end...": I'm assuming this is what you're seeing.
The variable's name implies it's the number of times Deelo's cum inside vaginas. So, uh, go outside and violate the elf until that number's 10 or more. What a silly way to measure if you'd beat the Princess. 'I guess you chose anal a few times too many on your trek to the Princess! You lose.'
You can track the number from Deelo's Status window in the menu, the number's shown as "Number of ejaculation:" in there.
