Can someone please explain to me what the fuck you're supposed to do there? And how you can even influence anything? All I see is that you click in each quadrant of that circle, and usually the NPC's total number goes down. What's the fucking point?
If you hover your mouse over a quadrant before clicking, you'll see the NPCs facial expression change. Simply pick small "pies" for the quadrants the NPC dislikes/hates, and large ones for like/love
If you're an apprentice in speechcraft you get one free rotate.
