The Mountain Dwarf is a hero in Dungeon Keeper. This red-haired dwarf is the battle-oriented counterpart to the Tunneller, but are not as strong as the hero units encountered later in the game. However, they are good scouts and craftsmen.
"A good hand-to-hand fighter who makes a point of stealing any gold he finds lying about."
— Dungeon Keeper Manual
Mountain Dwarves (also known as just Dwarves) are kin to Tunnellers, but trained for fighting instead of digging. In overall combat prowess, Dwarves rank closely with Demon Spawn and Skeletons.
Dwarves are excellent scouts: they are very fast (Speed 80, Imp is 96), and when they are designated by the game to lead parties, they cause the rest of the party to move apace with them. As with Thieves, Dungeon Keeper usually generates these heroes within parties that are under orders to loot the Treasure Room. This greedy behaviour makes them noticeably less-focused in battle and easier prey for your creatures.
Dwarves are good manufacturers, but due to their poor training skill, the level one captures a Dwarf is precisely the level he will remain for the near future. It's seldom worthwhile to capture and convert this type of hero. The mere existence of a Torture Chamber generally means the Keeper has access to superior creatures. They make a fine Skeleton, though.
