Stat Priority (5.4.2)
Stats are the core of your character and how you choose to balance those stats will greatly impact the effectiveness of your Destruction Warlock. Use this guide to select the stats that are the most important for your Warlock and learn how to prioritize those stats to optimize your performance.
Intellect > Spell Hit (15%) > Mastery >= Haste > Crit
Intellect Increases damage dealt by spells and slightly increases critical strike chance.
Spell Hit (15%) Any Hit Rating or Expertise will increase your chance to hit with spells and at 15% Spell Hit (5100 Rating) your spells can no longer miss on bosses. Spells missing is the easiest way to lose DPS, so always make sure you are at this cap. To check your hit percentage, open your character panel and then check under the Spell tab for “Hit Chance.” Make sure it is at or slightly above 15%.
Mastery Emberstorm increases the damage of your Immolate, Incinerate, Fel Flame, Conflagrate, and any spell that consumes Burning Embers.
Haste Reduces cast time, lowers the GCD, and can give extra ticks on DoTs. Also, thanks to Chaotic Energy, Haste increases Mana regeneration for Destruction Warlocks.
Crit Increases the chance for your attacks to critically hit for additional damage.
