More time! Blizzard have once again extended the Feat of Strength associated with the Mimiron’s Jumpjets mount from the Secrets of Azeroth Arcane Forge event! The mount will be available later as well, but the Feat of Strength was limited to only a few days and has already been extended once. However, Blizzard are now extending the period when you can get the Arcane Influence achievement until again, until 3 PM PDT/11:59 PM CEST Thursday!

Okay hear me out–
It looks like it’s actually, really, definitely going to be available until 23:59 CEST tomorrow, Thursday, September 14.
The event itself is pretty simple as you need to get Power Sources (which are marked on the map) to the Arcane Forge in Valdrakken. The event is active every 4 hours.
