Diablo II - Act I Complete

I've focused most of my gaming concentration on Diablo II in the past week, bringing myself presently to a point shortly into the second act. My Assassin is now level 19, and I'm mainly going the charge move/finishing move route along with the passive martial arts skills, though I'm trying out some of the traps, as well. To this point I've found a lot of white, gray, blue, and yellow items, but in a dungeon near the beginning of Act II's desert I found a green item, which I take it is part of a set. It's the belt, and it's called Frost something or other. I wonder if it's rare... because I'm playing an online game (even though I always play solo), I could join someone else's game to trade stuff, but I haven't bothered trying anything like that yet. Being only 20% into the games easiest mode, I'm sure I don't have anything special.

Apart from Diablo, the only thing I've been playing to speak of is Geometry Wars 2. I'm second among my friends list, although I'm not sure how the score is counted. It says I have 80million something points, while the guy ahead of me has 82million something, but if you go into the actual game and look at the individual leaderboards, his scores are way higher than mine all around. So, it's not just a simple sum of all 6 scores from all 6 modes; there's got to be some other mechanism at work here. My best mode is still Pacifism, where I've hit 37 mil, and I still can't finish Sequence. Awesome game.
