The Razormaw Hatchling used to be a drop from the Razormaw Matriarch, a rare spawn found in the Raptor Ridge Cave in Wetlands. This is no longer the case. The pet is now lootable from the Razormaw Matriarch’s Nest which periodically spawns on the raised peninsula entering into the larger central part of the cave. The rare Matriarch can still spawn and both can be up at the same time so enjoy the XP boost and pet from both if you’re lucky.
Every now and then, this little guy will let out a small roar. You won’t find him moving around much, as he’s probably the most obedient and docile of the bunch.
