It is VERY important to note that this is a rough outline of desired secondary stats. Your stat weights will be different than others due to varying gear sets and other external factors. The best way to tell what your own stat weights are is a raidbots.com Top Gear sim with Gems and Enchants taken into account. If you don't want to do that then you can just follow this.

Consumables

Enchants and Gems

1. Your first Spark based craft will be a Weapon of some sort with Darkmoon Sigil: Ascension.

• Crafting a Staff early on with 2 Spark of Omens is advised, but end patch BIS will have Mythic Queen Ansurek Main Hand and Crafted Offhand.

2. Your second Spark based craft will be a cloth armor item of some sort with Writhing Armor Banding.

• It is also possible to wear a 590 Crafted item of lesser value (such as Bracers or Cloak, which do not require a Spark of Omens) with Writhing Armor Banding Writhing Armor Banding Embellished, and craft a different piece of gear with you next spark that is of greater value. This may be the case for players who choose to craft a staff early, instead of a MH/OH Weapon. 

The openers and rotations listed below are what you want to follow in a normal opener and setting. At times these may change due to fight mechanics or needing to hold CDs. 

Single Target Opener

1. Precast Soul Fire

2. Conflagrate

3. Shadowburn

4. Summon Infernal (Trinkets, Potions and Racials)

5. Malevolence (if Hellcaller)

6. Shadowburn

7. Conflagrate

8. Chaos Bolt

9. Incinerate

10. Shadowburn

11. Resume Maintenance Rotation

You want to cast Shadowburn essentially on cooldown, even outside of execute. The ability has been buffed significantly in TWW. You will only cast Cataclysm in ST if your Wither/Immolate is going to fall, to re-apply Wither/Immolate.

If you are playing Channel Demonfire, cast it on cooldown. 

AOE/Mythic +

1. Cataclysm (if talented, to mass apply Wither as Hellcaller)

2. Summon Infernal (Trinkets, Potions and Racials)

3. Malevolence (if Hellcaller)

4. Rain of Fire

5. Channel Demonfire

6. Havoc

7. Conflagrate

8. Rain of Fire Spam

*Want to manually apply a few Immolates if noy playing Cataclysm (ex Diabolist).

*Can use Havoc to generate additional shards via Conflagrate/Incinerate casts in AOE. 

*See Havoc usage section for Havoc usage in Cleave vs AOE. 

Hellcaller will play Cataclysm over Inferno in Mythic +, while Diabolist will opt for Inferno. You will have to manually apply a handful of Immolates if playing Diabolist, once the pack is pulled. Cataclysm will apply Wither to all mobs hit by the effect as Hellcaller. 

If you are playing Channel Demonfire, be sure to cast it on CD in AOE, to extend the duration of your Wither/Immolate effects. 

Havoc Usage

There are a couple different ways to use your Havoc window which depends on the setting you are in. At times it will be used for shard generation to fuel more Rain of Fire casts. If you are looking to use Havoc in a setting where there are two targets, there are a few general guidelines you can follow. 

1. Try to enter the Havoc window with 2.5-3.5 Soul Shards.

2. Apply Immolate to both targets as long as they are going to live for 6+ seconds.

3. Be sure to not shard cap and be mindful of shard generation with Conflagrate/Incinerate casts.

4. Soul Fire WILL generate 2 shards and fully cleave if cast via Havoc.
