Troll

The Troll is a Creature type in Dungeon Keeper and Dungeon Keeper 2.

Description (Dungeon Keeper)

"A Troll has joined you. Skilled in the craft of manufacturing, trolls are best employed doing dark deeds in your Workshop. They don't complain about the hours, because their labours keep them away from combat."

Trolls excel at manufacturing items in the Workshop. If a workshop is available, they will head there by default. Trolls are the best creatures for manufacturing; the only creatures that come close (although they are still inferior) are Bile Demons, Orcs, and Dwarves. On the other hand, Trolls cannot conduct research, although they are passably good scavengers.

Trolls are not the best fighters, but they can still hold their own if trained to a high enough level. Training them can be beneficial for their manufacturing, too, as they learn Speed at level 4.

Description (Dungeon Keeper 2)

Essentially a manual worker by trade (trolls despise having to do research), the troll is a valuable ally, albeit a very ugly one. Its manual dexterity make it ideal for constructing and disassembling items in the workshop, and for disarming enemy traps.

The Troll is a weak figure. Even the Goblin is stronger than him. But his strength is not in battle, but more in his ability to manufacture. He is the fastest creature to manufacture, and will create traps and doors at lightning speeds. A few of them can arm your whole dungeon with traps and doors to keep heroes out for a long time.

The Mentor's thoughts

"A Troll arrives, attracted by the splendour of your Workshop. His crafting skills are set to serve you well as one who toil will make both traps and doors for you to use in your defence."

Trivia

The Troll can spot concealed traps and hidden doors.
He can take down traps and doors faster than normal creatures can.
Makes Traps and Doors faster than the Bile Demon.
The Troll is more like a Trow, a small troll native to Shetland in myths, rather than the standard big, strong and scary trolls of most other places.
