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. Go to the Chironasium (enchanting section) in Arcane 
University. Go to an
enchanting stand and enchant the necklace, rings, and armor with a Chameleon 
spell using the Grand
Soul Gems. 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. You can now steal from a shop without the 
shopkeepers doing
anything. Your enemies will also just stand still unable to attack, allowing 
you to go into Sneak mode
and attack for 4x to 6x damage, and pickpocket without consequence (except 
on guards who can
catch you if you fail, but still cannot attack you if you resist arrest).
