Mined from secret locations in the Astral Plane, this malleable metal holds its shape only in the hands of a psionic being. When an item forged with ferroplasm is unattended or held by a nonpsionic creature, it melts and temporarily loses all special powers. But when wielded by a psionic creature, such an item immediately springs back into its true shape and regains all abilities. In its proper form, a ferroplasm item glows with a violet light (illuminating a 10-foot-radius), unless the item’s owner mentally quenches it. In an area where psionic powers do not function, it collapses as if in the hands of a nonpsionic creature.

Ferroplasm adds to the quality of a weapon or suit of armor based on how much of the material is used. Weapons fashioned from ferroplasm have a natural enhancement bonus to attack and damage. Armor fashioned from ferroplasm has a natural enhancement bonus to AC. These bonuses do not stack with other enhancement bonuses. Weapons or armor fashioned from ferroplasm are treated as masterwork items with regard to creation times, but the masterwork quality does not affect the enhancement bonus of weapons or the armor check penalty of armor.

Ferroplasm has hardness 20 and 40 hit points per inch of thickness when in its true form, and a hardness of 5 and 10 hit points per inch of thickness when soft.
