Legendaries and Legendaries, Oh My

With the release of Tomb of Sargeras, the new legendaries have been released with an ilevel of 970, compared to 940 of previous legendaries. Also released was a method to raise the ilevel of existing legendaries to the new level, 940 to 970.

I spent time after my LFR runs yesterday trying to get enough writhing essences, you need 50, to upgrade one of my legendaries. You get the essences from raid bosses and the caches you get for completing the sets of world quests.

I had gotten a number of essences from my LFR runs and I had a couple sets of world quests to complete, three actually. The second set I completed was in Stormheim, and imagine my surprise when I got this from my cache.

Even after getting that, I still had to finish my last set of world quests in Suramar to finally get the last essences. Once I had my 50, I turned that quest in and used the reward item to upgrade my other legendary chest piece for my tank spec.
