Hill-trolls were a species of trolls who are closely related to mountain-trolls and cave-trolls, and appear in The Lord of the Rings: The Battle for Middle-earth II: The Rise of the Witch-king, as part of the Angmar faction. Arador, the fourteenth chieftain of the Dúnedain, was slain by one of these trolls.
Hill-trolls are savage and reckless beasts that crave grand treasures and weapons. They also let out a blood-curling battle cry to frighten their enemies. Hill-trolls usually wear overall-like pants that are made of brown leather. The hill-trolls often favour large axes to use in battle, making them effective shock troops.
Hill-trolls live alone or in small groups and commonly live in the Ettenmoors or Angmar, some heading down to the Trollshaws for the winter. They dig small caves in rock faces in the Trollshaws, and live in these for a few months at a time. They kill, eat, and steal from any travelers who dare to take shortcuts through the Trollshaws, although it is safe for travelers in the summer, when the trolls are mainly in the north.
