Through the door is a tremendous statue standing on a pedestal of stone. At first you think it must be made of shattered glass, but its brilliance is too great, nearly blinding you. It’s made of diamonds! Its hideous eyes darken and grow fearsome, and the diamond face and hands begin to jingle loudly as they move.
The diamond golem will attack until it is either destroyed or it destroys the party.
Diamond Golem (AC -6; MV 9; HD 22; hp 100; THACO -1; #AT special; Dmg 5-50; SA none; SD hit only by magical weapons of +3 or better, magical resistance 90%; XP Value 19,000).
The diamond golem is one of Zagig’s final creations, a behemoth he manufactured to protect his most valuable treasures. The diamond golem depends upon an outside light source for its animation -- until someone enters the room with light the golem remains silent and inanimate in the darkness. Once hit by light, the diamond golem will immediately animate and remain active for one hundred rounds after the light source is extinguished.
The number of attacks the golem gets in a round depends on the quality of light hitting it during the previous round.
Darkness: 1
Torchlight: 3/2
Light or light from any other 1st level spell: 2
The glow from a magical weapon, continual light, or light from any 2nd level spell: 5/2
Light from any other magic object or from any 3rd level or higher spell: 3
Magical attacks may affect the golem's number of attacks, as well. Hitting it with a fireball will do normal damage, but its light will let the golem attack three times in the next round.
Magical darkness (darkness, 15'radius or continual darkness) slows the golem. Each such spell cast upon it forces it to stop moving and attacking for one round.
If destroyed, the diamonds will turn to dust, worthless to the PCs.
