With 50% of the Bastion of Twilight reduced to lootable corpses, we smacked some silly trash around for a bit and quickly cleared a path up to the Ascendant Council. These four elemental superdudes were solely tasked with keeping the door to Cho'gall's beauty parlour firmly locked, so we knew what we had to do in order to gatecrash Captain Eyeball's parade.
I'll admit it took us a while to get the hang of things in this encounter - so many abilities to contend with, lots of boss re-positioning and plenty of fire to stand in! That being said, we effectively split our DPS in phase 1 to bring both the fire and ice chumps down to 25% at the same time, and readied ourselves for plenty of levitating and grounding in phase 2. Another fine display of split DPS and we pushed the encounter into phase 3, which was the real test of our gear and button-mashing abilities! With our main tank dragging the uber elemental boss around the room, we popped Heroism and went nuclear on his rocky, windy, toasty, drenched ass. The final 25% went quickly enough, and victory was ours!
After the loot was distributed, we gathered round what was left of the boss (which resembled a large polished turd), pondered for a moment before summoning the mandatory dancing dwarves for our celebratory team photo.
We gave Cho'gall a couple of attempts to get a feel for his abilities in phase 1, and can safely say that they hurt a lot. His days are numbered, though!
