Electromagnetic Field (Ex)

A plasma ooze generates a massive electromagnetic field that disrupts electronics and interferes with signals. Electronic signals, such as those employed by comm units, do not function within this area. When a creature activates an object with charges that is in the area, that object must succeed at a DC 22 Reflex save or it is drained of all charges and the action is lost. A technological construct that begins its turn in this area must succeed at a DC 22 Reflex save or be staggered and unable to use energy-based attacks for 1d4 rounds. A creature or object that succeeds at its saving throw is immune to the plasma ooze’s electromagnetic field for 24 hours.

Magnetic Draw (Ex)

As a move action, a plasma ooze can draw all Medium and smaller creatures and unattended objects of no more than light bulk that are within 100 feet up to 30 feet toward itself (Reflex DC 22 negates; this DC increases by 5 for technological constructs and technological items).

Plasma Drain (Ex)

Once per day as a full action, a plasma ooze can drain the charges of plasma weapons within 100 feet to regain a number of Hit Points equal to the most charges drained from any one battery. Each weapon can attempt a DC 22 Reflex saving throw to negate this effect for that weapon.

Plasma Pulse (Ex)

A plasma ooze’s plasma pulse is a ranged attack with a range increment of 60 feet and the severe wound critical hit effect.


Environment any solar or vacuum
Organization solitary

Enormous crackling lattices of electromagnetic energy, plasma oozes are significant threats to even the most experienced spacefarers. Usually taking a roughly spherical form, a plasma ooze pulses with a brilliant array of pink, purple, and blue light, connected in a complex network that reaches whitehot intensity at its many nodes. These oozes are most often seen in the immediate vicinity of a star’s surface, but explorers have occasionally sighted the mysterious beings hovering near powerful electromagnetic phenomena in numerous system, both in the vacuum of space and on the surfaces of volatile planetoids.

A typical plasma ooze is a rough hemisphere approximately 20 feet in diameter, weighing close to 100 tons.

The origin of these oozes has been hotly debated, with ancient scholars speculating that the creatures originated on the Plane of Fire and were drawn to an inhabited system’s sun. However, nearly a century ago, the discovery of deserted cities within the sun—along with modern claims by Plane of Fire natives that yet more civilizations exist in deeper layers of the sun—spawned a host of new theories, as abundant as the oozes are rare.

Plasma oozes’ strong electromagnetic field makes them extremely dangerous to encounter in the vacuum of space, since even shielded starships can find themselves adrift after crossing paths with one. Similarly, in the rare instances when a plasma ooze takes up residence on a populated planet’s surface, the edges of its territory are often marked by the dusty hulls of disabled vehicles, their former owners having wisely abandoned them to live another day. Few living creatures survive contact with a plasma ooze, but those that do often bear terrible wounds that serve as permanent reminders of such oozes’ fearsome power.
