Fire Mage

A single target fight. Note that as Night Fae you can use Shifting Power while hiding behind the pillars for maximum uptime.

Focus on the boss or the dog depending on your group's needs. Use Mirror Image and Blazing Barrier when target by Sinseeker to improve your survivability.

If add damage is required, use Flamestrike instead of Pyroblast during Combustion on the adds.

Make use of your mobility with Soulshape, Shimmer and Alter Time to carry the seeds away from your team.

Make use of your defensive abilities such as Mirror Image, Blazing Barrier, Alter Time and Ice block to mitigate the encounter's damage.

Nothing special to really add here, focus on the boss and use Combustion when the adds spawn, making sure you spread Ignite to them.

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).

Use Flamestrike if add damage is required. Otherwise, focus the boss and spread your Ignite.

Nothing special to do as a fire mage here, just focus the boss and spread your Ignite to the adds.
