Survive animal attacks
Certain Creatures are aggressive, and will engage you in combat. These animals are Badgers, Bats, Boars, bears, lynx, and Trolls. These Creatures are capable of killing you by attacking your character once it is knocked out. In order to keep safe, follow the following steps.
Step 1: Stay Alert
Keep an eye on your minimap for aggressive animals. Note that certain custom clients have a feature to draw red circles around aggressive animals. This does not indicate a "dangerous area", it is merely to add visibility.
Step 2: Know where it's safe
Be aware of safe areas from animals. Animals can move through shallow(light) water at full speed, and can find their way around small cliffs and other obstacles. In addition they can break most structures, the exceptions being houses, palisades and brick walls. Do note that animals can aggro over walls and walk through open gates. Animals will not follow you into caves or houses.
Step 3: Know your opponent
Not all animals are the same. For example, you can outrun boars on 'run' speed. Bats attack in groups, but ignore you while wearing a bat wing. Bears build initiative before attacking. Animals are more likely to attack the faster you walk by them, though even the slowest speed is still dangerous.
Step 4: Run Forrest, Run!
