The Attack Matrix

Inspired by this post at Gorgonmilk I decided to make something similar for my Yaqqothl Campaign. I don't like the one provided in the 3LBBs that much, mostly because it looks totally weird to me. Also, you'll notice that on Yaqqothl you always have to roll "higher than 4", no matter how high your level is. Moreover, it works with THAC0 and I love it, because of my poor memory.
