Trolls are monsters that come from Scandinavian myths and Nordic fantasy. Trolls are called Trows in myths from the Shetlands. Trolls are not especially intelligent and are often associated with an element. The most common description of Trolls is a tough ugly creature with tough rock like skin. Trolls have the powers to regenerate even if hacked apart. The only way to stop a Troll regenerating is burning the monster. Trolls diet is unusual, as they will eat anything including metal, bone, wood and rocks. The stomachs of trolls contain very powerful digestive acids. This has led Trolls to an unpleasant form of attack of vomiting over their target; this is an extremely painful attack. Sometimes Trolls use basic hand weapons such as clubs or large stones.
