The nightmare of orcs and other dwarven enemies, this rare golem is constructed by dwarves themselves. The process is as rare and secretively kept as the manufacture of the most powerful dwarven magical weapons.
A hammer golem stands about 9' tall and weighs about 2,000 lbs. It resembles a gigantic stone dwarf (beard included) covered in adamantine half-plate. Its forearms have been replaced by two weapons - a hammer on the right arm and a pickaxe or axe on its left.
Hammer golems are made by dwarven priests for use as guards, warriors, or massive miners (they can tunnel through rock at their burrow speed). A hammer golem created for war possesses a greataxe on the left arm, and one for mining has pickaxes on both.
Combat:
This golem attacks only if ordered by its master, if it encounter orcs, or if it is kept from its assigned task. The latter condition allows it to attack if someone tries to get at what the golem is guarding when it is carrying out this task. When without a master, a hammer golem attacks anything in front of it until the opponents leave it or its charge alone or are dead. If the opponents are goblinoids, only their death or the golem's destruction will break off its attack.
Pounding Force (Su): A hammer golem can employ pounding force once per minute. The pounding force inflicts 4d6 points of damageand pushes away all creatures within 60 ft. of the hammer golem. Treat this as a bull rush with a +15 bonus on the Strength check (+9 for Strength 29, +4 for being Large, and +2 for charging bonus, which it always gets). The force always moves with the creature to push it back the full distance allowed, and it has no speed limit.
Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.
Magic Immunity (Ex): A hammer golem is immune to all spells, spell-like abilities, and supernatural effects, except as follows. A wish spell affects the golem as the caster wants. A stone to flesh spell restores the golem to full hit points.
Converted from Dragon Magazine #193 (Live Statues and Stone Men: Golems of the Underdark by John Power)
NOTES:
*The pounding force ability used to have the effects of a repulsion spell. However, this spell has changed drasticallly from 2e to 3e, so in order to capture the feel of the ability, I changed it to be similar to a Bigby's forceful hand spell and the ring of the ram.
The golem costs 100,000 gp to create, including 1,500 gp for the body and 11,200 gp for the adamantine half-plate. Assembling the body requires a successful Craft (sculpting or masonry) check (DC 20). The ritual requires a 16th-level dwarven creator who can cast divine spells. Completing the ritual drains 2,000 XP from the creator and requires animate objects, geas/quest, repulsion, prayer, and spiritual hammer.
I did this conversion in January '02, so we might need to start over.
