I fought Krosis and won at level 10 1/2. *All proud of self* At first I thought I was actually taking the draugr himself and putting it on my face... That was weird. Then I realized, oh, it's his mask, everything's cool, and now I have Krosis all over my face.
Krosis means sorrow in the dragon tongue, though I suspect Krosis the Dragon Priest had no emotions after gaining power from the dragons even in undeath.
Though I have to say, Dragon Priests are reminded of Liches, but Dragon Priests are much more powerful since they possess masks unbound by time and space and Liches are the next and maybe the final step in a necromancers cycle of Necromancy and undeath.
Yeah, they do remind me of the Liches too, but i think dragon priests are way cooler. Now imagine the power that Dovahkiin really posses. After collecting all of the dragon priest masks, Oh and also all of daedric artifacts. Yup dragon born is not to be fucked with.
