Lava Body (Ex)

The magma ooze is formed of molten rock. Whenever a creature strikes a magma ooze with a weapon, that weapon takes 4d6 points of fire damage unless the attacker makes a DC 19 Fortitude save. Damage caused to weapons in this manner is not halved, but hardness does help prevent some of the damage dealt. The save DC is Constitution-based.

Vulnerability to Water (Ex)

A significant amount of water, such as that created by a create water spell, the contents of a large bucket, or a blow from a water elemental, that strikes a magma ooze forces the creature to make a DC 20 Fortitude save to avoid being staggered for 2d4 rounds. A magma ooze that is immersed in water must make a DC 20 Fortitude save each round (this DC increases by +1 each subsequent round) or become petrified, reverting once the water is gone.


Differing types of molten stone and the nature of the magic that created them can influence what types of magma ooze form.

Brimstone: Influenced by fiendish energy, brimstone magma oozes stink of evil, and the patterns of cooled stone and hot lava on their surfaces resemble tortured or demonic faces. They have the fiendish creature simple template.

Crystalline: formed from rock densely laced with rare minerals, crystalline magma oozes have hot gases trapped within their bodies. Striking a crystalline magma ooze with a non-reach melee weapon causes this gas to erupt, dealing 1d6 points of fire damage to the attacking creature.

Poisonous: Whether from toxic metals or magical contamination, these oozes are deadly poison in addition to mobile burning death. A poisonous ooze is +1 CR.

Magma Ooze Poison: Slam—injury; save Fort DC 19; frequency 1/round for 6 rounds; effect 1d2 Con; cure 2 consecutive saves.
