I finally GM's begging as well (thanks to 1.2 points from SoTs). I have a great friend that helped me out with them. It is an awful skill to raise. After 90, it seemed like I was gaining .2 points every couple of hours. At 98.2, I almost gave up. I tried going to the Satyrs but that seemed harder and time consuming. My method was going town to town and to every new npc I could find (tram and fel). It took me a week and a half to get from 50 skill to 98.2. I'm glad it's over, lol.
I went trick or treating last night and after 5 hours combined, I only got 2 sets of the rare items and 2 creepy cakes, 1 spider web, 1 harvest wine, and a pumpkin pizza.
