Shot from a perch you have already built well above his head, near his spawn point, in a tree that is indestructible. Get 250 frost arrows to be on the safe side. Youtube has videos on either method.

This method doesnt work anymore. Bonemass will flee and heal pretty fast. You have to be at the ground, or at least within the reach to prevent him from fleeing.

It can work, but you must be lucky to spawn him in the trees. https://steamcommunity.com/sharedfiles/filedetails/?id=2721254376
