Slow Time. With enough physical training and some decent equipment, you could realistically become a superhero with that Shout.
Now I'm wondering if Slow Time can slow bullets down enough to dodge them - 1/10 speed is still 30 miles per hour if I remember my physics correctly, and with you at 1/2 speed - you might not be able to dodge in time.
Still, it would be incredibly useful in pretty much any situation, right?
Oh god now I can't unsee this:
Creedy: Bollocks. Whatchya gonna do, huh? We've swept this place. You've got nothing. Nothing but your bloody knives and your fancy karate gimmicks. We have guns.
V: No, what you have are bullets, and the hope that when your guns are empty I'm no longer be standing, because if I am you'll all be dead before you've reloaded.
Creedy: That's impossible. Kill him.
[the fingermen open fire on V, but he still stands after their clips are empty]
V: My turn. TIID KLO UL!
[V proceeds to kill all fingermen with his knives before they manage to reload]\
It's official: V was a Dragonborn.
Storm call. Chaotic evil while remaining inconspicuous (Bar the shouting bit). Maybe I can profit from this to fulfil my neutral evil tendencies. Or, Slow time, if only to see the effects of my actions. Will I live longer to troll people by slowing down time and removing what they own from them at lightning speed?
Slow Time would be cool, but overall I think Bend Will or Dismay would be more useful for those of us who have relatively normal lives. Being able to control or frighten people would be awesome. Animal Allegiance would be awesome too. I'm trying to think of any other shouts I'd like to have... does Elemental Fury work with unarmed? If so, I'd go TO TOWN on anyone who looks at me the wrong way.
