Blood Death Knight is a uniquely interesting tank, where most tanks try to mitigate damage in some form, Bloods mitigation is healing itself back up which will
have you saying “I’m the Healer Now”, cause you will be topping the healing meters with huge absorbs and death strike healing. Blood offers a lot of anti mechanic abilities and control over the battlefield.
Blood is an interesting builder spender tank with two resources, two spenders, one builder with runes and runic power. Runic power is the lifeblood of the spec, if you can’t Death Strike, you die. Build Runic power through spending runes, spend by Death Striking.
Blood is in a funny state, its one of the lower dps Tank specs, but wields the highest amount of survivability.
