how do i get rid of Shauna on the roof with Suni?
Make sure your fitness is higher. Not sure the exact number but I'd say 50 should be more than safe. You also will need to ensure you're knowledge is pretty high...it has been awhile since i've played so I cant remember the exact number. But have at least 75 knowledge at all times. Certain intellectual moves require it. And I know for a fact you will need fitness and knowledge to survive that encounter. Aslo if you have high relationships with other futas you can call them for help.
Good luck!
