Fire of Earth (Ex): An earth demon's blood runs as hot as fiery lava. Whenever the creature is hit with a piercing or slashing weapon, its burning blood sprays out in a 5-foot-wide, 10-foot line toward the origin of the attack. Any creature caught in the spray (normally only the opponent that made the attack) must make a successful Reflex save (DC 17) or take 1d8 points of fire damage.
Earthen Form (Su): At will, an earth demon can use a standard action to take the shape of a Medium-size rocky outcropping, a small boulder, or other earthen terrain feature. In this form, the earth demon cannot move, does not gain a Dexterity bonus to armor class, and it gains a +10 competence bonus on Hide checks when in surroundings that would normally include such features. The demon does not gain any special protection in this form; it takes damage normally from spells and weapon attacks. The earth demon can return to its humanoid shape at will as a move-equivalent action.
Outsider Traits: An elemental demon has darkvision (60-foot range). It cannot be raised or resurrected.
A subtype usually applied only to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned (see Damage Reduction).
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned (see Damage Reduction).
