I've been playing Oblivion again lately, and it seems like Skyrim is lacking in some enchantments. I am talking about enchantments like invisibility, night vision, light, etc. Enchantments that are active spells basically. What do you guys think about it? What about having enchants that cast spells for you, such as a ring that did summon familiar that used charges?

How would you equip the ring as a weapon? How would it be better than using a staff?
