Commander Ghulil

This is the third boss that you will face in Black Talon... He stands on a platform with two standard healers (Star Medics) at each side.

Strategically the fight is simple; take out the medics and then continue dps on the boss while moving out of radials which spawn a immolation droid that spews out AoE fire. The fire from the droid leaves a DoT that stacks, but doesn't really start to hurt until around 2 or 3 stacks. If you find yourself bored with moving around so much, move at the third droid.

This one is a little harder.

He'll call down some small probes that will create a ring of fire around them. He needs to be kited away from this.

If you are using your companion to tank, you'll need to turn on passive, so he runs back to you, and kite the boss out of the fire.

It's possible to solo this boss as a Level 11/12 Sith Juggernaut with Vette. The fight will take a couple of minutes and you'll need a few med packs. If you can't find a group for whatever reason and want some nice upgrades, you can do the entire Black Talon run yourself. In short:

1) You might have to wipe once to get rid of the Medics (they won't despawn). Also make sure you kill the two droids on either side of the room.
2) Once Ghulil is alone, put Vette on passive. Jump in, throw up Sabre Ward, and start hammering away at him to build threat. Kite him around, use med packs to maintain 50 per cent or more HP. Use Force Scream if you can spare the rage.
3) Use Force Charge to close in and give him a few whacks to build more threat, then run back out. You should be able to maintain a good distance since he periodically stops to drop those fire bots.
4) When you have a decent amount of threat, order Vette to attack and make sure she doesn't stand in fire.
5) Keep kiting him while putting Vette on passive if you think she's about to pull aggro. You'll be able to run Ghulil around in circles while waiting for your med packs to come off cooldown.
6) Vette is the one who's going to win this for you. Make sure she lives.
