ABILITIES
Magic Immunity (Ex): A shadesteel golem is immune to any effect that allows spell resistance, with exceptions as noted below.
    Any spell or effect with the light descriptor or using positive energy, that would normally affect a shadowsteel golem directly, causes the golem to speed up as if affected by haste for 2d4 rounds. Any spell or effect with the darkness or shadow descriptor that would normally affect a shadesteel golem directly, instead heals it for number of hit points equal to its effective spell level. These benefits occur only once for any given spell or effect, regardless of its duration.
Negative Pulse Wave (Su): The shadesteel golem can radiate a burst of inky black negative energy as a free action every 1d4+1 rounds. The pulse deals 12d6 damage to all living creatures within 40 feet of the golem (Fort DC 25 half). Undead creatures within the area are instead healed of 12d6 points of damage, and any turning effect they are under is broken. A death ward or similar effect can protect a creature from this ability. The save for this ability is Constitution-based.
Shadow Blend (Su): In any conditions other than full daylight, a shadesteel golem can disappear into the shadows, giving it total concealment. Artificial illumination, even a lightor continual flame spell, does not negate this ability, but a daylight spell will.

NOTES

Note A spellcaster with at least 4 levels in the dweomerkeeper prestige class (CD), and the capability of casting awaken construct (SpC 21) in tandem with the Intensify Spell epic feat, is required to produce this creature.
Note Energy resistances were added to the golem, with consideration to its material composition compared to that of living flesh.
