Essentially, you've got two DPS roads to take as a DK. Stamina-based og Magicka-based. Skills usually base damage on either of them. What I did was stacking all attributes into Magicka, pulling off a nice DD build focusing on Ardent Flame abilities. It rocked when leveling, but as soon as you're ready for Veteran Dungeons, you'll need to spec more carefully to not be as squish.
