Aura of Sickness (Su)

As a free action, a magnesium golem can generate an aura in a 10-foot radius spread that sickens all living creatures entering the area for 1d4 minutes if that creature fails a DC 16 Fortitude save. A creature that successfully saves cannot be affected again by the same magnesium golem’s aura of sickness for 24 hours. A delay poison or neutralize poison spell removes the effect from a sickened creature. This is a poison effect. The save DC is Constitution-based and includes a +2 racial bonus.

Dexterity Damage (Su)

A magnesium golem’s slam attack deals 1d4 points of Dexterity damage to a living foe if it fails a DC 14 Fortitude save. The save DC is Constitution-based.

Immunity to Magic (Ex)

A magnesium golem is immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and effects function differently against the creature as noted below.

A magic attack that deals water damage or creates water slows a magnesium golem (as the slow spell) for 3 rounds, with no saving throw.

A magical effect that deals fire damage breaks any slow effect and heals 1 point of damage for each 3 points of damage the attack would otherwise deal. If the amount of healing would cause the golem to exceed its full normal hit points, it gains any excess as temporary hit points. A magnesium golem gets no saving throw against fire effects.

Rust Vulnerability (Ex)

A magnesium golem is affected normally by rust attacks, such as that of a rust monster or a rusting grasp spell.

Magnesium Golem Construction

A magnesium golem’s body is sculpted from 1,000 pounds of pure magnesium. The magnesium is mixed with rare chemicals totaling 4,000 gp. Assembling the body requires a successful DC 14 Craft (armor or weapons) check.

CL 9th; Price 27,000 gp


Craft Construct, geas/quest, hold monster, limited wish, polymorph any object, stinking cloud, creator must be caster level 9th ; Skill Craft (armor) or Craft (weapons) DC 14; Cost 15,500 gp

Anodized (Improved) Magnesium Golem
The golem is anodized during the creation process by submerging it in a solution of acid. During this time, the creator must cast lightning bolt or some other electricity-based effect into the solution. This deals no damage to the golem. After four hours, the magnesium golem is removed from the solution. An anodized magnesium golem is identical to a normal magnesium golem detailed above but it does not have the rust vulnerability trait of the normal magnesium golem. This increases the golem’s price by 2,000 gp.
