Vicious Ophidian, as previously mentioned. Relequen is good. I beat it for the first time without trial sets on a stam sorc using briarheart, battlefield acrobat, and Velidreth. It’s not so much the sets as it is practicing and knowing mechanics. You could make it happen in Hundings and NMG if you wanted. If you have the trial sets then I would definitely run VO with relequen or some other set of your choice.
