First, let me state the following: This isn’t very difficult, but it took me 3 hours to figure it all out as I’d never seen the fight prior to trying to solo it. I’m writing this just in case other boomy’s out there want to try and solo it, and would appreciate saving some time. (I’m not going into the mechanics of fight, there is a million guides for that. This is specifically what made it easiest for me, as Boomkin.)
Talents which nullify difficulty:
Wild Charge (allows you to bound forward in travel form every 15 seconds, or disengage as boomkin) really negates the troubles which arrive via the “Comet Impacts” (the purple orbs that send you flying.)
Resto Affix allows you to roll some hots and pop the occasional swiftmend when needed. This is obviously useful.
Things to bring: Damage Potion, Drums for Bloodlust/Heroism.
The most difficult part of this encounter (in my experience) is dealing with the Fel Claw debuff. Once those stacks get high, he will start hitting hard. Now, I’ve heard people say, “Kite him” but this is, in my experience, not very effective. You will lose way too much damage in this process. It can be done, but I prefer another solution: use your CD’s / pots / drums intelligently.
The debuff is applied in 3 separate phases.
P1: 100%-80%.
P2: 80%-40%.
P3: 40%-0%.
So, In P1, being as it’s the shortest phase, don’t use potion or anything longer than 2 min CD. Just your rotation and convoke should be enough to end this phase before he does too much damage.
In P2, just use all your CD’s. (But remember to top yourself off before he goes into the sky, and the platform goes black.)
In P3, use Drums & Potion (and obviously any CD’s that come-up.)
This worked for me, and it really made it easy. GL!
EDIT: I didn’t use food or flask. So, while I’m 220 Ilvl, I’m sure you can do this “strategy” with much less gear if you use flask/food.
