There is the spear that can blind on hit (I think) and gives you extra damage against creatures with many eyes. You assemble it from the broken pieces found on the dwarf True Soul and the Owlbear that did him in. If my memory serves me it's called Absolute Sight or Vision, or Sight/Vision of the Absolute.
Edit: A related question, has anyone managed to brand more than one party member with the Absolute's mark? I gamishly assumed that once I've branded my main character it would apply to all my party members, but when I distributed the items my companions still got the curses from using them, and by then I was to far ahead to want to reload and try to brand them all.
