Candle in the Wind

There are 4 braziers that are on fire in the room Blade Lord Ta'yak is in, all somewhat in the middle of the room next to pillars. And then you have 4 braziers that are not lit up, 2 on the left end of the room, 2 on the right end of the room.

After the boss reaches 20% phase 2 starts and most of his room will be filled with winds. The 4 braziers in the middle become clickable and will give you a Flame Bearer buff that lasts for 30 seconds. Now you need to run to the end of the room, either left or right, and click on the 2 unlit braziers to light them up.

I would say that the easiest way to do this is to get the buff, run to the side where the boss is at and light the braziers on that side. Then when the boss reaches 10% he switches sides and you need to get a new fire buff to light the other 2 braziers. Note that the fire buff isnt consumed once you light a brazier up, so you can light both of them with just one buff, as long as it doesnt run out.

You could think that, but you'd be wrong. It's actually a reference to an old [npc=475] fairy tale, told by elders among the [npc=80] regarding the valor of [npc=327] in his defense of the sacred [item=58903]. It was a mighty struggle for survival. Years ago the [npc=80]s traveled far from Troll invaders to the south. [npc=327] kept the flame safe through both [spell=16914] and [spell=109443] before the entire clan settled in Elwynn Forest. The clan believes the candle brings powerful luck, and hold it sacred. Elton John! Hah!

The Candle in the Wind achievement is soloable at level 100+. Stand right on or next to one of the four burning flames ("braziers") by the center pillars as you bring [npc=62543] to 20% health, which pushes him into the final wind phase, while repeatedly and quickly clicking on the flame. For a split second, your cursor will change to a gear and the flame will become clickable. and you'll get the 30-second [spell=128949] buff before you get whirlwinded to one side of the room. When you regain control of your character you have 20 seconds or so to easily light the two braziers on the side you land on.

Next, run against the wind while dodging whirlwinds until you can click one of the four burning flames near the middle for a fresh [spell=128949] buff, then get to the end, and light the remaining two. Moving and dodging and clicking can take a little practice, and some classes have speed boosts and other abilities that make it easier, but any class can do it.

After you reach the side with the boss and light the 3rd and 4th unlit braziers, attack and kill the boss. He switches sides at 10% health, so you'll have to run through the whirlwinds again, unless you applied some strong damage-over-time spells that finish him off after he switches.
