You're not meant to use it as your main weapon. Only use it in sneak
Except that used that way it
is your main weapon, since you don't need anything else as you can clear a dungeon without even being
detected, let alone retaliated against, due to how badly a high-level fully-perked Sneak skill breaks the AI. In fact, the
only opponents who ever see me are Dragons, because they start out alerted unless you get lucky and catch them sleeping on the word walls they guard. Well, that, and any dungeon wherein I have a 'teammate', because they do not understand how to fight from stealth and aggro everything in a 5-mile radius...
