Unused look : This look is not available in the game.
Can only be used by hunters in the Beast Mastery spec. Minimum level 10 in Dragonflight.
This is the original blue devilsaur colour, which was added in the Mists of Pandaria beta test but was removed and replaced by the current blue devilsaur look before release. Hopefully it could be restored to the database and used somewhere in the game.
