If you come across a low level Morrelatops on its own, you can easily down it using roughly 10 arrows, no misses. If you do miss, it's okay, if the area is rocky enough and you're fast, you can punch it when it gets stuck.
In a group they attack, individual they run. Pick the lone wolf and lead it by facing the way you want it to go and trap it against a wall or rock or a safe place. No missed shots, no wasted resources, and a easy Morrelatops tame.
