Unused look : this look is not available in the game.
This look is currently only applied to a saddled model but could be perfectly adapted to make a wild hippogryph.
Special Skill Required : In order to tame members of this family, you must use the Tome of the Hybrid Beast to learn Hybrid Kinship. This is only available for purchase after (i) unlocking all artifact traits on the Beast Master artifact, Titanstrike and (ii) completing the Hunter Order Hall campaign for 7.2, which is gated and will be fully unlocked around 14 June. The tome is Bind on Account and may be passed to Hunter alts that are level 110 but haven't otherwise met the criteria.
