Starlight Golem

It's been a while since I've posted a monster, hasn't it? Here's a simple little companion piece to a creature I statted up a while back: the Moon Golem.

Starlight Golem

An ethereal, almost invisible gossamer-like being of indefinable, vaguely humanoid shape, a Starlight Golem is crafted on nights when the moon is new and the firmament is the only illumination. The skill and power necessary to create one is far beyond the limit of all but the most mighty of magic users.

Starlight Golems are mindless creatures who exist only to kill. They can be given only simple orders such as to guard, attack, or stop.

Intelligence: Non
Alignment: Neutral
AC: -4
Movement: 6, or Fly 12 (E)
HD: 12 (60 hp)
THAC0: 8
No. of Attacks: 2
Damage/Attack: 3d8/3d8
Special Attacks: A Starlight Golem can forgo its two ordinary attacks and attempt to envelop an opponent. This attack treats all targets as AC 10 (though dexterity bonuses apply) and causes 2d10 damage.
Special Defenses: A Starlight Golem can be hit only by silver weapons, or weapons enchanted to +2 or more. They take half damage from cold attacks.
Size: Large (8-10')
Morale: Fearless (20)
Other: Starlight Golems are non-corporeal, and can pass through doors and walls without impediment. In battle they always attack the nearest target, or attack randomly if targets are equidistant. They are almost invisible, and always surprise their opponents. When it is a new moon they are at their strongest, and on such nights they gain 2 HD and increase their movement to 12 (Fly 18 [D]).
