This is a 2h leveling build for a Death Knight. Hit Plague Strike first and Icy Touch second, getting the damage bonus to Icy Touch, to get your diseases on the Target, which increases your attack speed by 20% with this spec. Then hit obliterate with your remaining Frost and Unholy rune. This spec allows you to hit obliterate without consuming your diseases on the target. Use your unused blood runes on heart strikes. The mob should be dead by this point. You should heal through a lot of the damage you take with this spec, between Blood Worms, Blood Aura, and Vendetta. If you need to you can use Rune Tap but you should never need to use Death Strike for healing over Obliterate.

• Frost Death Knight:

With current beta itemization and leveling, 2h weapons are your best be for effective tanking due to the lower hit rating cap and on higher %dmg dealing spells. Focus on causing Death Runes which allow you to change your approach at any given time, even allowing up to 4 Death Strikes for burst healing. Life Tap for soloing and last minute saves. Lichborne and Unbreakable armor provide additional DPS and survival. Blade barrier offers a secondary (almost passive) avoidance stat, while Bladed Armor gives you more STR from the Armor you will be stacking naturally. Last but not least, Hungering Cold followed by a Death Chill / Howling Blast for burst AoE threat when needed most.

• Unholy Death Knight:

Talents in this tree have a variety of functions including summons, diseases, and PvP-focused abilities. This version of Unholy utilizes Dual Wield though the heavy use of Necrosis and Blood-caked Blade. Corpse Explosion, Wandering plague and Unholy blight give high AoE DPS as well. As you progress to 80 points should be spent in Blood tree to decrease threat and for Bladed Armor in order to increase Attack power.
