I'm assuming you are a magicka based DPS DK since you are a dunmer, pick up a destroy staff and put your range abilities on the destroy staff. GLHF

Then put a bow on your second bar and put your buffs there along with a couple from the bow line; maybe green dragon blood or obsidian shield? Really though it depends on what you want for your rotation and what skills you'll need in different dungeons.

Drop your points into Stamina and use health enchants and or Food for as much health as you need, as a Stamina DK you can Tripot or use Weapon Power/Crit/ Stamina Potions or Health/Stamina/Weapon Power.

The main point to running a 2H secondary bar with DW as primary is for Rally (This is something Stam NB do "mostly") but DKs have Green Dragon blood that works as a decent self heal and stamina regen.
