As guilds continue to defeat Mythic Fyrakk in Amirdrassil, the elusive Cinder of Companionship required for Hunters to tame the fiery flying spirit beast Nah'qi and Feather of the Blazing Somnowl granting Druids a new flight form are now confirmed to be awarded upon learning Reins of Anu'relos, Flame's Guidance! While this revelation may be cause for rejoice, it also comes with the unfortunate realization that all three rewards appear to be locked behind Mythic difficulty.
It turns out all three are awarded together, and only on Mythic difficulty!
Although Nah'qi was tamable for a brief time after the launch of Patch 10.2, by using a Shaman or Mage to crowd control the spirit beast during taming, this was quickly patched out with all instances of the pet removed. Attempting to tame Nah'qi normally returns the message «you haven't proven yourself to this spirit,» which datamining told us the Cinder of Companionship was clearly meant for, though its acquisition remained an elusive mystery up until this point.
