OK let not get carried away with saying stuff like Ring of the great Ancestors - Raise Dead 10/day, or Greataxe of improved vorpal, which kills on any crit hit. But what new named items would you like to see be added.
Like heartseeker, a +1 longbow that kills any target with a beating heart on a confrim crit. IE a vorpal bow.
Or Evershot. +3 longbow of transmutation of evershot. Evershot supplies a endless supplies of arrows for the archer
Otto dance robes. When a mob hit the user they must save or be effected by Otto dance.. Also the devs could have fun with this one by making the robes look like something from the saturday night fever. Just image your dwarf barb in that white suit with big collar
Or add weapon with of Otto dance that on a hit the target must make a save of be effect by ottos dance. Kind of like a para but instead they dance.
