Oh shit, so, I was going to this place for a quest, and noticed there was a dragon head marker nearby, so I went to that first. I took down the dragon easily enough, but then there was like lich king asshole there, too. But the dragon word wall had THREE words on it. And I happened to have 3 souls saved up. I learned the Throw Voice shout which, if you use all three words, only has a 5 second recharge. It makes enemies think you're somewhere you're not. And I'm playing as a thief/assassin. The only way I beat the lich kind asshole was by sneaking over, getting a sneak attack with my bow, using the marked for death shout (another amazing power, it permanently reduces health/defense, and it stacks, if you keep doing it) and then I would hide until he couldn't find me, and sneak attack/mark for death again.
So yeah, the marked for death and throw voice shouts are pretty much going to make my assassin character unstoppable, now.
God I love this game.
