What a p.i.t.a. Have cleanse on speed dial when fighting this guy. He spams affliction so he can get his auto crit thundering blast. A friend and I did this event with a marauder sith warrior with Quinn (healing) and a powertech bounty hunter with Mako (healing).
- If you see a purple circle on the ground, move
- kept companions on heal watch with attacks disabled
- heal through force damage
- interrupt embrace of sel-makor is a must
If affliction doesn't get cleansed asap, the thundering blast crit will do way too much damage. We went in originally as 47 (even match), but wasn't able to actually put him away until we came back at 49. The mission log says the mission is only 47 *normal, but IMO, should be heroic 2+ or even heroic 4 if attempting to do it at 47 or lower.
This fight is extremely easy (just solo'd as a 45jug). Here is how you do it.
1.) Bring healer pet
2.) Position your pet somewhere in the middle of the platform or at least in a fashion such that he can heal you while you execute the strat.
3.) LoS kite this jerkface around pillars. Try to keep him between your pet and you coz while you are LoS your pet will take potshots at him and will actually do most of the damage.
4.) Poke him with instant abilities when you can and always try to keep threat so that he doesn't turn around and munch your pet.
5.) Win :D
