Not all magic items are for humans. Rewrite of my original and premiere submission, Horse Brass
Once upon a time this sword may have been a sight to behold, but no more. Rust and decay now tarnish the metal of this forgotten relic, and those who stumble upon it are more likely to toss it than use it.

Ah, you are awake now I see. Wondrous news. I realized that you have no idea what is transpiring so I will be blunt so you may understand it. It is rumored that you are one of the best jewelers and metalsmiths in the region and for that you are lucky enough to have been chosen to create an item that will change the world. And afterwards, you shall be set free. My word on it.

A nifty little encounter appropriate for any powerful sorcerer/magically adept monsters lair.
When the party have penetrated to an appropriatly impressive level/room they encounter The Door, this door is a vessel through which the Sorcerer/Monster can safely work against any intruders, the door is heavy duty iron bound studded oak wrought with craft skill and magic, set in the middle is a crystal orb, once the party get within a preset distance the orb flickers briefly as the door warns its "master" of the intruders, the master can then effectivly possess the door itself, this means that all movement the door is capable of (i.e. opening and closing) come under the control of the master, the master can also cast spells from the door as if he were there himself, all the while any damage that is inflicted in return merely damages the door, this will in effect ruin any of the parties chances of surprise, allow the master to assess the parties abilities while remaining safe and sound and finally will probably cause the party to waste some of their juicier items/spells on a chunk of wood and iron, and if the master happens to have a deadly spell or three it could also reduce the size of the party,
Of course if you wanted to be really nasty you could have the door open to admit one person and then slam shut on the second person (squish) whilst blasting away with every spell in the mastrs repetoir
