Gurthan Iron Maw
Mogu'shan Palace (Dungeon)
110-120 Rare Scales***
Greater Vigilant, Zuldazar
**Creatures in Zandalar (Zuldazar, Nazmir, Vol'dun) do not scale for Alliance hunters, and creatures in Kul Tiras (Tiragarde Sound, Drustvar, Stormsong Valley) do not scale for Horde hunters, except in defined war campaign areas. Outside these areas they will always appear level 120 but can be tamed when the hunter is level 118.*If a creature's level is noted as 'Scales' then it will vary with the Hunter's level within the constraints of its level range.
