Pretty straight forward fight. Make sure you use Alter Time when targeted by Echolocation to return to your original position.
Also, make sure when you use shifting power the boss gets damaged.

Nothing special to really add here, focus on the boss and use Combustion when the adds spawn.
The Council of BloodSingle Target
Don't bother with Ignite spreading and cleaving here as the health of the bosses reset. Just focus on your assigned target.
A single target fight. Make sure your second combusts aligns with the boss's damage amplification (Destructive Impact).
The optimal trinkets for this fight are Empyrial Ordnance and Badge. Make sure you use Ordnance 20 seconds before you want to use badge to get the double on use uptime on the boss's exposed phases.

On Phase 1 and Phase 2, you will want to Flamestrike with Combustion to deal with the skirmishers. Same applies on the intermissions, where you will want to focus down the commandos when their shield is up.
