Retains its original name after taming. Karkin can appear on a floating rock off either the east or south-east side of Fireplume Peak. Even though this beast appears two levels higher than you, you can tame it if you're at least as high as its minimum level.
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.
