The texture file for this look is not currently attached to this model, but would work perfectly if copied to it. We include it here out of interest. The texture's current location in the game database is: Creature/EliteHippogryph/EliteHippogryph.blp. The look was created for the Emerald Hippogryph mount, which seems to be almost identical to the hippogryph models introduced in Legion.
*Level scaling: In Shadowlands most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
