Use Dragon's Breath at the end of Combustion if you won't be able to fit in another spell.

Note: With effects that increase your haste like Time Warp and Power Infusion, the rotation is the same as before with the difference that you will be able to weave in an extra Scorch-Pyroblast at the end.

Firestorm Proc

If you get a Firestorm proc you ignore the rotation and spam Pyroblast for the duration of the proc while maintaining 2 stacks of Infernal Cascade.

Outside of Combustion Rotation

When outside of Combustion your rotation is the following:

1. Rune of Power
2. Fireball until you get a heating up proc
3. Fire Blast
4. Pyroblast

Use Shifting Power when Combustion and Rune of Power are on cooldown while you have 0 Fire Blast and Phoenix Flames charges left.

Combustion Rotation for Mythic+ or 3+ targets

1. Phoenix Flames
2. Fire Blast
3. Flamestrike
4. Phoenix Flames
5. Fire Blast
6. Flamestrike
7. Phoenix Flames
8. Fire Blast
9. Flamestrike
10. Fill up the remaining duration of Combustion with a combination of Scorch and Fire Blast into Flamestrike.

Combustion Rotation with 3+ targets or really high haste

With really high haste levels i.e Time Warp or a priest's Power Infusion do the following rotation:

1. Phoenix Flames
2. Fire Blast
3. Flamestrike
4. Phoenix Flames
5. Fire Blast
6. Flamestrike
7. Phoenix Flames
8. Fire Blast
9. Flamestrike
10. Shifting Power
11. Dump your remaining Fire Blast with a Combustion of Scorch to cast Flamestrike

If you get a Firestorm proc you ignore the rotation and spam Flamestrike for the duration of the proc while maintaining 2 stacks of Infernal Cascade.

Playstyle

Make sure you enter Combustion with 3 Fire Blast and Phoenix Flames charges.

When your target is below 30% health, you cast Scorch due to the talent Searing Touch to generate Heating Up procs.

On 2 or more targets, if no priority damage is required, you hard cast Flamestrike with Flame Patch.

Make use of your many defensive abilities like Blazing Barrier, Alter Time, Mirror Image and Ice block to stay alive.
