Burn Through (Ex) A pyroceros flames are extremely potent, burning through lesser protections with ease. Each time a creature is exposed to a pyroceros's fire damage, its fire resistance is reduced by 5 (10 if the pyroceros scored a critical hit with its gore attack) after the damage is dealt, cumulatively. Fire resistance provided by constant sources, such as racial ability or permanent magic item recovers at the rate of 5 points per minute since the last exposure to pyrocers's fire damage.
Fiery Hide (Ex) A pyrocers body cracks and splashes molten lava. Whenever a pyrocers is damaged, it deals 2d6 points of fire damage to all adjacent creatures.
Fiery Horn (Ex) A pyroceros's horn inflicts additional 8d6 fire damage on hit. When a pyroceros makes an attack at the end of charge, it splashes molten lava, inflicting the fire damage in a 15-ft cone instead. Creatures and objects other than the one hit by the charge can halve the damage with a successful Reflex saving throw (DC 23). The saving throw DC is Constitution-based.
Lava Bathing (Ex) Exposure to molten lava heals pyroceros for amount equal to damage it would normally inflict. Pyroceroses can swim in molten lava as if it was water.
Stable (Ex) A pyroceros has a +10 racial bonus to CMD.
Pyroceroses are fierce, territorial, elementals composed of molten lava, living along the borders between the Planes Of Earth and Fire. They are animalistic in their intelligence and behavior, resembling rhinoceros and similar large land animals of the Material Plane, occasionally fighting elemental predators.
From time to time, they might appear near elemental rifts on the Material Plane, and are hard to get rid off, because of their stubbornness.
