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⚠️
Thank you for reading and sorry for my bad English, I'm French.
Run as fast as you can when you see it, if that doesn’t work, Get on flyer and fly away, if you don’t have a flyer, well there’s only one way to say it. You’re Dead!!!
With its high health and good melee you can grab it with a quetz and drop it into an enemies base so it will take a toll on their dinos opening them up for an attack soon after the Yeti is dealt with
This albino gorilla is your exp friend, get a good cave pets like cave dire wolf, give your wolf an ascendant flak helmet, shoot the head of the yeti (more damage) with shotgun, and done. You have ~2000 exp (if you play in medium)
If u tamed a wolf from this cave by kill him and take his implant and call him out the cave made a helmet for him and u can kill yetis and any creature in this cave cuz ur wolf will be lvl 900 and yeti gave a lot of exp for killing him i did that many times
