Spec Specific Azerite Traits:
Cascading Calamity: Grants you a 15 seconds haste buff for each time you apply Unstable Affliction on a target already affected by it.
Deathbloom: Seed of Corruption deals additional damage if it detonates early.
Dreadful Calling: Makes Unstable Affliction deal additional damage and reduces the cooldown of Summon Darkglare by 1second for each Unstable Affliction.
Inevitable Demise: Makes Agony stack up a buff up to 100 stacks, increasing the next use of Drain Life.
Sudden Onset: Agony deals additional damage and starts with 4 stacks.
Wracking Brilliance: Increase your Intellect for 6 seconds every other time your Agony creates a shard.
Azerite traits rotation chances:
Cascading Calamity: Instead of refreshing Unstable Affliction shortly after it runs out, you simply refresh it shortly before.
Inevitable Demise: Applying Agony stacks up a buff on you. You want to use Drain Life around 48-50 stacks and don’t need to move for the whole duration. Haunt and Unstable Affliction should also be applied beforehand.
Recommended Azerite Traits
Tier 1 & 2:
Generally speaking you want Wracking Brilliance, Cascading Calamity and Treacherous Covenant as often as you can get. For Multi Target fights like High Tinker Mekkatorque, Inevitable Demise is incredibly good.
In most cases Overwhelming Power is the best Tier 3 trait. The only exception are execute damage reliant bosses like G’huun, High Tinker Mekkatorque and Jaina. Gutripper is perfect for this kind of situation and can make the difference between a kill and a wipe.
