I've tooled around a bit with the CS to make my own equipment.
For instance, Aetherial Ring a Mana regenerator that is 'cursed' ( restore mana 2 then a script when you wear it adds the ghost shader to your character, and drain luck 25)
Then there is 'Tremiki the Hungry Blade' a soul trap Madness claymore that absorbs health and fatigue, again with a scripted curse: It drains your Str, End, Fatigue, Health and Stunts your magicka. You also get a text message: "You feel a strange hunger overcome you, one you are unsure you can sate. . ."
