I killed this chick as a lvl 28 shadow (consular). Heres a nice trick for ya. First of all, Theron is a MUST, at least at this level. Interupt her force blast and her projects EVERY time using either our kick, stun, or knockback Force speed out of her aoe. The range is MUCH larger than the blue circle so **** Stagger your CDs throughout the fight Make sure your heroic moment is up, but only use it on a confident pull, its a long CD Finally, heres a sweet trick...once your HP startes to drop below 50%, use force lift on her. This will incapacitate her, give theron some time to heal you up, and let you use mind crush for some extra damage and dot. Its a fantastic break during the fight. happy killing!
