Dungeon Specials (also known as Magical Items in Dungeon Keeper 2) are a set of bonuses that can be found in some levels. They are often well hidden, being difficult to find or reach, but their rewards are most useful, and can easily change the tide of battle.
Your imps will carry specials they find to your library for safe-keeping. The AI keepers will also hoard any specials they find, however the AI will never activate the special. This means you can capture it from them.
Dungeon Keeper 2Edit
Once the terrain under a magical item is claimed, the claiming player can activate the item by clicking on it. If the owner's imps get to it before it is used, they will carry the item back to a Library as long as there is shelf space remaining. Once it is placed on a shelf, it can be activated either by clicking on the item itself, or by clicking on its icon in the Spells tab of the GUI.
Note: only 10 magical items will show up at a time in the Spells tab. If you have more unused items than that, you will not be able to activate some of them unless you find and click on them in your Library.
