Gemstone golem

Gemstone golems were beautiful but deadly automatons created from various precious gems. The three most common forms of gemstone golem included those made from rubies, emeralds, and diamonds.

Behavior
In order to control a gemstone golem during battle, a circle of at least a dozen wizards, led by a superior, was needed. Directing the golem required the circle's complete focus, and any interruption resulted in the golem wandering aimlessly. The control extended for one mile beyond where the circle was first formed. Gemstone golems were deactivated when not in use by a circle.

Combat
Regardless of the type of gemstone used during construction, these golems were highly resistant to physical damage and were practically unstoppable when unleashed.

History
The first recorded creation of a gemstone golem was by the god-kings of Mulhorand. The secrets to their construction was lost for centuries, until in 1368 DR when the Red Wizard Zulkir Aznar Thrul discovered the ancient Mulhorand manuals that detailed the process and went about unleashing them upon the Rashemaar.

During this time Thrul experimented with creating golems from gemstones other than diamonds, emeralds, or rubies but the results were always mixed.

Ecology
Gemstone golems were controlled almost exclusively by the Red Wizards of Thay.

A gemstone golem would collapse into a pile of rough cut precious gems and powder when slain. The gems were quite valuable and the powder could be used by wizards for spell components.
