Coal Golem

Coal Golems are humanoids formed of coals, glowing as if still afire. Their eyes and mouth show the mighty fires that rage within, blazing like torches.

Combat: Coal Golems attack with their powerful fists, punching twice a round for 2d4 damage per hit, plus setting any combusibles within 5 feet ablaze and dealing 1d6 damage to all within 10 feet of a battling Coal Golem. Those immune or highly resistant to fire take no damage from this aura and only 2d3 per hit.
Starting on the third round and on every round therafter, a Coal Golem can breathe fire in a 60*20*5 cone, dealing 10d6 damage.
Coal Golems are immune to fire and heat attacks and are immune to spells which target the mind. They are similarly immune to any evocation or alteration spell, no matter what the spell result.
The spell Minor summoning 1, for reasons known only to the creators of these golems, causes the golems to slow as the spell for a six round duration.

Habitat/Society: As artificial constructs, Coal Golems have no habitat or society. The mage who commands their amulet, usually worn as a nacklace, has complete control over them and need not retain concentration.
Librams of Constructing Coal Golems are very rare, commanding 60,000 gp on the open market.

Ecology: Coal Golems take nothing from the environment around them. They do, however, give off great quantities of heat and draw creatures to them as a free source of heating. One enterprising mage uses his Coal Golem as the source of steam in his sauna business, placing the golem below a trickle of water. Another uses his as a portable tunnel creator in his wandering the northern glaciers.
