Troll Hoard

Troll Hoards are small groups of chests found in caves in biomes in which Trolls spawn.

Spawning
They are most commonly found underground in the Ettenmoors, but can also be found in the Trollshaws, Coldfells and Angmar, basically any biome you can find a normal Troll in. They are not spawnable structures but a group of chests on the floor or in the walls of a cave.

Loot
Troll Hoards can yield great treasure if you stumble upon one or more of them. They usually contain pieces of Ranger and High Elven Armor and High Elven weapons, as well as silver coins, sliver and gold ingots or nuggets, and rings. Iron or bronze equipment, bones and skulls are some of the more mundane items that may be encountered. Mithril rings can also be found in the depths of a Troll Hoard…

In the Troll Hoards of the Ettenmoors biome, it is possible for chests to spawn containing troll totem pieces, which are needed to summon the Mountain Troll Chieftain. This is a fairly quick way to get loot if you are aligned with Angmar or are a very brave adventurer.

Stategies
Just be careful the owner isn't lurking about, as they are often close by!
