Boars, Wolves, Lox, Moose, and Asksvins can be tamed to make them friendly with the players and help against fighting other hostile creatures, while Chickens/Hens are already tamed once they are hatched from an egg. They can all also be bred, which enables easy access to their drops. Tamed wolves can be commanded to guard a specific place or to follow into a battle. Tamed Lox and Asksvin can be ridden.
Tamed creatures keep their stars and will pass them to their offspring. This makes 2-star creatures very valuable for taming for their increased drops and combat ability.
