So, as the title says, what do you think Dovahkiin has to be able to accomplish to be considered truly powerful?

Clear out an entire fortress/dungeon without anybody knowing you were ever there? Being able to annihilate a dozen bandits with a single spell? Tossing a platoon to the ground with your Voice? Crushing a dragons skull with your weapon?

Personally, I think that my thief is truly powerful/skilled when he can go through an entire dungeon WITHOUT killing a single soul. It takes skill to kill, and more not to. As for my warrior, I truly feel powerful when I can go toe-to-toe with two giants, and come out on top.

What about you, the forum community. What do you think would spell your Dovahkiin achieving true power? Are you attempting to do it, or have you already done it?
