If you're having trouble on Arch-Tempered Kirin

Try going solo. I swear AT Kirin has like, 25x the health in multiplayer. You die in one hit either way, so make it go by faster. I have only ever finished multiplayer once out of like, 30 tries. The other 5 times were solo. I didn't fail once when I was by myself. It's way, way easier imo. Good luck either way hunters. <3 (Also, AT Kirin is almost gone, so get it done while you still can.)
