Diamond golem

Diamond golems were the strongest of the beautiful gemstone golems. They were made entirely from diamonds.

Description
Diamond golems usually stood tall and weighed thousands of pounds. They usually resembled muscular humans clad in armor, sometimes carrying swords and shields, though these were purely cosmetic additions and had no bearing on their combat effectiveness.

Combat
Diamond golems were totally immune to all forms of heat, acid, and electricity.

They struck at enemies with their fists, backed by the strength of a storm giant, with devastating blows. Strong magical weapons were needed to piece their diamond armor. Diamond golems were mostly immune to any nature-based magic, making them extremely useful against the witches of Rashemen.

A diamond golem could spray a cloud of tiny diamond chips in all directions, causing great harm to any creature within a radius. They could also emit a blinding blast similar to the divine sunray spell.They could perform each of these attacks three times per day.

The shatter spell was effective at harming diamond golems. Crystalbrittle reduced their immunity to nature, heat, acid, and electricity-based magic while also allowing slightly weaker magical weapons to penetrate their armor. A mending spell partially healed a diamond golem while glassteel restored them to full health.

Diamond golems, like all gemstone golems, were formidable opponents in battle. The easiest way to combat them was to disrupt the circle of wizards that controlled them. Any disruption to the circle caused the diamond golem to wander aimlessly.

Habitat/Society
Diamond golems were used by the Red Wizards of Thay. A circle of at least a dozen wizards, led by a superior, was needed to control them.

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