Complete all the Mage Guild Recommendation Quests so that you can enter the Arcane University. Get five or more Grand Soul Gems and fill them with Grand Souls. Buy a Chameleon spell such as Shroudwalk from a mage. Go to the place where you enchant weapons with the following: two rings, one necklace or amulet, and any two pieces of armor. Enchant the rings, amulet and armor with the Chameleon effect using the Grand Soul Gems. You will get 20% Chameleon for each of the equipment, for a total of 100%. Equip them all at once and you will be invisible to everyone. You can now steal directly from people and attack anything without fear of retaliation because they cannot see you. Use this to cause mischief around towns, finish quests or dungeons without getting in battles, or to defeat an enemy without getting hurt. Note: You must wear all the pieces at once to be 100% invisible. You can use any other type of equipment as long as there are at least five pieces and all have been enchanted using Grand Soul Gems. Some enemies may hit you once, but they will not do so again.
