Just walk up behind the yeti and hit it will a club, then run towards your friend - bola him, and knock him out with the club. Feed him narcoberries and then run away like sonic. Your friend should take care of it
This thing has the strength of 100000000000 alpha rexes, the colour of a dire wolf and the body of a gigantopithecus. Only option, bola your friend and run, if you don't have anyone, hope you had a good life
Use a good pack of allos because of their pack boost and their bleed (-5% health, no matter the amount yetis have) or use good wolves also because of their pack boost, ⚠️you might loose a few of them⚠️
