Stat Priority (5.4.8)
Stats are the core of your character and how you choose to balance those stats will greatly impact the effectiveness of your Blood Death Knight. Use this guide to select the stats that are the most important for your Death Knight and learn how to prioritize those stats to optimize your performance.
Mastery > Stamina > Expertise (7.5%) = Hit (7.5%) > Parry > Dodge > Haste
Mastery Mastery Blood Shield adds an absorption shield with every Death Strike. Mastery leads to slightly smoother incoming damage that may be easier for your healers to manage.
Stamina Increases your total health. You want to stack just enough Stamina to survive a couple of hits from bosses so that your healers have time to react.
Expertise & Hit These two stats are effective for both threat generation and survival. You need 7.5% Hit (2550 Rating) to no longer miss your attacks, 7.5% Expertise (2550 Rating) to no longer have attacks dodged, and 15% Expertise (5100 Rating) to no longer have your attacks Parried. However, the 15% Expertise goal is not advised as your stats are better spent elsewhere. Properly stacking Expertise and Hit ensures that your attacks do not miss and that you maximize your threat and Rune usage.
Parry Allows you to avoid an incoming physical attack. Parry has very low diminishing returns which means you can stack a lot of Parry and it will still be an effective stat. As a rule, you want 2.5x as much Parry as Dodge.
Dodge Allows you to avoid an incoming physical attack. Dodge has a higher rate of diminishing returns than Parry and should not be stacked as high.
Haste Increases the speed of Rune regeneration which results in more frequent use of your threat and survivability abilities.
