You can now steal from a shop without the shopkeepers doing anything. Each enchantment gives you 20% Chameleon effect, so all five enchantments will make you 100% Chameleon, which is not only invisible but also allows you to attack, steal, open, and pick-up without being revealed. Go to an enchanting stand and enchant the necklace, rings, and armor with a Chameleon spell using the Grand Soul Gems.
Go to the Chironasium (enchanting section) in Arcane University. This trick requires access to Arcane University, a Chameleon spell, two rings, a necklace/amulet, any two pieces of armor (preferably a helmet and shield you could use any armor for this, but you may want to enchant them with defensive magic later), five Grand Soul Gems with Grand Souls in them, and 8,000 gold.
