Retains its original name after taming. Only Beast Masters of level 45 and above can see the item required to summon this beast, but any hunter with the Exotic Beasts skill (level 39) can tame it! To summon Gon you need to click on the Spectral Eggshell (not always present, long spawn timer) at the burning pile of skulls by Shadow-Walker Zuru.
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.
