Untameable look : This look is not known from a tameable creature.
Can only be used by hunters in the Beast Mastery spec. Minimum level 10 in Dragonflight.
You must learn a special skill to tame Gargons. It is taught by a Gargon Training Manual, a guaranteed drop from Huntmaster Petrus, a rare NPC that can appear in the Witherfall Ruin area of south-east Revendreth. It appears this manual can only be read at level 60.
Level scaling: 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.
