SPECIAL ABILITIES

Berserk (Ex)

When a neutronium golem takes damage that reduces it to half its maximum Hit Points or fewer, and whenever it takes damage while it has half its maximum Hit Points or fewer, it must attempt a DC 13 Will saving throw. On a failure, the golem goes berserk.

While berserk, the golem uses its actions to make a full attack or to move and attack. If it can’t reach a creature, it attacks objects. The golem can attempt a DC 13 Will saving throw at the end of each of its turns to end the berserk state. If the golem’s creator communicates with the golem to calm it, via comm unit or from within 60 feet, and succeeds at a DC 10 Charisma check, the golem receives a +2 circumstance bonus to this saving throw.

Comm (Ex)

A golem can receive wireless communications (and thus commands from its creator) at planetary range.

Light Immunity (Ex)

A neutronium golem does not interact with visible light, so it is immune to laser weapons or any other attack based on visible light. In any area of dim, normal, or bright light, a neutronium golem is invisible.

Magic Immunity (Ex)

A neutronium golem is immune to any spell or spell-like ability that allows spell resistance, unless the spell specifically lists constructs in its Targets entry. In addition, certain spells and effects function differently against the golem, as follows.

If the golem is inside the area of a control gravity spell used to increase gravity and fails its saving throw, instead of the usual effects of the spell, the golem becomes Tiny (reducing its space and reach to 2-1/2 ft.) and sinks partially into the ground, becoming pinned for the duration of the spell.

If the golem is inside the area of a control gravity spell used to reverse gravity or create an area of zero-g and fails its saving throw, in addition to the normal effects of the spell, it partially loses its humanoid shape as it becomes Huge (increasing its size and reach to 15 ft.) for the duration of the spell. In this state, it is staggered.

The golem automatically fails its saving throw against discharge and greater discharge but has a unique reaction to these spells. Discharge and the area discharge effect of greater discharge heal the golem for 5d8 Hit Points; the targeted discharge effect of greater discharge heals it for 11d8 Hit Points.

The golem can be targeted with a recharge spell, but this spell has a unique effect upon it. If the golem fails its saving throw, it loses its immunity to electricity and light, becoming visible as a creature of highly reflective metal for 2d4 rounds.

ECOLOGY

Environment any
Organization solitary or gang (2–4)

Neutronium, the material found in the heart of a neutron star, is one of the densest substances in existence. Just a spoonful of it would weigh billions of tons and, if dropped onto the surface of a planet, would simply puncture the planet’s crust until it reached the core. Further, neutronium possesses some unusual properties; because it has no electrons, it does not interact with light. Scientists have studied neutronium for centuries, with many of them pursuing the practical goal of weaponizing the substance.

A neutronium golem is invisible in light but pitch black in darkness; this quality makes it both a deadly assassin and a useful guardian. Species with natural darkvision— like drow—can easily see and interact with these golems in the darkness that is their natural environment. But when intruders trespass into the lightless chambers where a golem is stationed, any illumination they bring with them only serves to make the neutronium golem more dangerous.

In addition, the incredible density and neutral charge of neutronium grants the construct a number of immunities even beyond those normally associated with a golem. However, a neutronium golem does have weaknesses. By delivering a charge to the neutronium that makes up the golem’s body, its immunity to light is temporarily negated, causing it to become visible. The magical forces which give the neutronium a humanoid form are also precariously balanced, so rapid fluctuations in gravity can disrupt the golem’s body. Finally, like many golems, it has a tendency to fly into an uncontrollable rage when damaged.

Although the process for creating neutronium golems is a relatively recent development, rumors persist that older neutronium golems exist elsewhere in the galaxy. Based on the writings studied by the drow scientists, neutronium golems were originally created to guard sacred sites.
