We've found three Oculi. So even if it is the best sorceress weapon in the game (except for Wizardspike or Suicide Branch for specialized builds, and I suppose swords and bows for combat sorceress), it's not impossible to find ;) . There are 44 other items (or, rather, 43, since we had found the Mane) which we still haven't even seen; some of these are dream items :p .

I suppose if it gave skill points or stat points, it'd at least be good for something. I guess then I'd have to skip the WP if I want to kill Nihl and still have the red portal, though ;) ...
