What's the point of enchantable staves? If I am playing a mage, I already enchanted my gear so I don't use mana. If I am not a mage, I need the spell to enchant the staff, and I think I need to be capable of casting it. Therefore I cannot get very good spells. The best would be to summon dremora lords but obviously my stealth archer doesn't have the spell, nor could he cast it with such low conjuration.

Note I am playing on Master difficulty.
