The mound of purplish, metallic liquid looks simply to be a puddle, until it seems to gather in on itself and move toward
you. Without warning, a spike of the liquid launches from the puddle, hurtling at you at rapid speed.
Residents of the darker caverns and mines, ferroplasmic oozes hunt the mine shafts that are home to the metal of the same name. No one knows how these creatures came to be, but they are feared by duergar for their deadly efficiency in dispatching their prey.
Composed primarily of ferroplasm in a liquid form, ferroplasmic ooze is typically a large puddle about 3 to 4
feet in diameter and weighs around 300 pounds due to the density of ferroplasm. If compressed into a sphere, it is
about two gallons in volume.
Combat
When hunting, a ferroplasmic ooze attacks by firing its ferroplasmic projectile. If cornered, it attacks by slamming
its bulk onto its prey, taking full advantage of the heavy metal that makes up its form to squeeze the life from its
victim.
Constrict (Ex): A ferroplasmic ooze deals automatic slam damage with a successful grapple check.
Ferroplasmic Spear (Ex): A ferroplasmic ooze is able to project portions of its own form at its opponents. Treat
this attack as a ranged attack that deals 3d6+2 points of piercing damage with a 10 ft. range increment.
Improved Grab (Ex): To use this ability, a ferroplasmic ooze must hit with its slam attack. It can then attempt to
start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a
hold and can constrict.
Metallic Diet (Ex): As part of its sustenance, ferroplasmic ooze will ingest iron or steel and convert it into an amount
of ferroplasm equal to half the initial weight. If killed, the ferroplasmic ooze decomposes into one quarter its body
weight in usable ferroplasm.
Ooze traits: Ferroplasmic oozes are immune to mind-affecting effects, gaze attacks, illusions, and other attack
forms that rely on sight, poison, sleep effects, paralysis, polymorph, and stunning. They cannot be flanked and are
not subject to critical hits.
