Retriever (Dungeons & Dragons)

In the Dungeons & Dragons fantasy role-playing game, the Retriever is a Construct (though for some reason, some sources denote it as a demon). It resembles an enormous mettalic spider, with a body the size of an ox and 14 feet legs. Its back and head are interplaced with dozens of glossy metal plates arranged in a jagged fasion. It is black in color, and has six eyes and a pair of mandibles.

Characteristics and habits
Retrievers are constructed (typically by evil mages, warlords or demons) to find, capture or recapture lost or desired objects, runaway slaves, wanted criminals, or such. When ordered to find such a thing, it does to inerringly, both doing it without question and somehow knowing exactly where the to-be-retrieved thing is and how to retrieve it. In order for this to work, however, the master has to have either seen or touched the item/being to be retrieved.

If, by any chance and for whatever reason, the Retriever has to challenge what it has to retrieve, it is capable of doing so. From its eyes, it is capable of firing four different eye weapons; fire, frost, electricity and petrification. It can also attack with its four frontmost claws. The Retriever usually weakens its foes first using its fire/frost/electricity eye weapons and its claws, before switching to petrification to immobilize the prey. It then picks them up and places them in the mouth, and takes them back to their master.

Retrievers are apparently unable to speak.

They are chaotic evil in alignment.
