The wolf - There are some loner wolves roaming this isle. Wolves are fast, tough and dangerous. Often they are the hunters and not the hunted. It is a good decision to engage them in combat only with decent equipment and to fight a wolf one on one. If there's nothing else, you can always eat a hunch of wolf, and sell its fur.

The bear - Bears are hard to beat! Keep that in mind before challenging one. If you are inexperienced and don't have good equipment, retreat is the tactic of choice. Best kill bears in small hunting parties and use terrain to your advantage.
