Hey! Im a kind of expert on this boss and after my 120kill in norms I have some probability on the mob drops.

In my ONLY NORMS RUNS I have never picked up an egg, claws or hunting drops in my handful of HR runs ive collected 2 pairs of claws and 1 singular egg

It seems hunting loot is REALLY rare on norms since ive been told they drop but personally have never seen it. If you have questions or need proof of anything ask away!
