Book of Vile Darkness
The statistics and ability descriptions are for both Belial and Fierna, except where noted. Fierna typically enters battle with fire shield and magic circle against good active. Belial favors his ranseur and goes into a fight with see invisibility, magic circle against good, and unholy aura active.
Fear Aura (Su): As a free action, Belial and Fierna can create an aura of feat in a 20-foot radius. It is otherwise identical with fear cast by a 15th-level caster (save DC 42). If the save is successful, that creature cannot be affected again by this fear aura for 24 hours. Other baatezu are immune to the aura.
Spell-Like Abilities (Belial): At will - charm monster, deeper darkness, desecrate, detect good, detect magic, geas/quest, greater dispelling, greater restoration, hellfire storm, locate creature, locate object, magic circle against good, major image, produce flame, raise dead, see invisibility, suggestion, teleport without error, unholy aura, unhallow, wall of fire; 1/day -- dominate monster, symbol (pain), wish. Caster level 20th; save DC 24 + spell level.
Spell-like Abilities (Fierna): At will -- desecrate, detect good, detect magic, dispel magic, fireball, fire shield, flame blade (double damage), hellfire storm, magic circle against good, produce flame, suggestion, teleport without error, wall of fire; 1/day -- fire storm, meteor swarm, wish. Caster level 20th; save DC 24 + spell level.
Baatezu Traits: Belial and Fierna can communicate telepathically with any creature within 100 feet that has a language. In addition, they can see perfectly in darkness of any kind, even that created by a deeper darkness spell. Belial and Fierna are immune to fire and poison, and they each have acid resistance 20 and cold resistance 20.
Regeneration (Ex): Belial and Fierna take normal damage from holy and blessed weapons of at least +4 enhancement.
Summon Baatezu (Sp): Three times per day, either Belial or Fierna can automatically summon 5 barbazu or hamatulas. Alternatively, Belial (but not Fierna) can summon 1 pit fiend.
Possessions: Belial's +4 ranseur is a minor artifact that causes those it strikes to feel wracking pains that drain 2 points of Dexterity. A successful hit also imposes a --4 penalty on attack rolls, skill checks, and ability checks (Fort DC 24 negates). The latter effect must be removed by a heal or break enchantment spell.
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).
A subtype usually applied only to outsiders native to the lawful-aligned Outer Planes. Most creatures that have this subtype also have lawful 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 lawful alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the lawful subtype overcomes damage reduction as if its natural weapons and any weapons it wields were lawful-aligned (see Damage Reduction).
