A lot of Pkers most of the time will have a positive hell resistance, but it is hard to have the that number be high. My LvL 81 Pally HandOfDivinity was almost gone in a couple hits by a LvL 67 FoH pally, so it does considerable damage. By the way my regular Light Resis is 30, and he reduced it to -100, so like Great-Thanatos said, it doesn't take a lot of points into conviction to take resis down, not to mention the lowering of defense too.
