Particularly with high levels you'll probably hit the bug where it starts dropping health instead of food and you can't feed it anymore. Solid tame if you can get it to work, but go in expecting disappointment
For beginners these things will spot you in a split of a second so don’t even think of going up to it with a stimberry in your hot bar. Instead, get a ghille suit and sneak behind it and feed it a beer! Don’t use stimberries it is pain And time consuming unless you have a bush of stimberries. They eat berries after they are tamed though. Not beer.
