FIEND
Fiends appear in countless forms, although their physical characteristics often reflect some sin or other vile aspect.
Species Traits
Fiends share the following traits:
Darkvision (Ex): Fiends have darkvision out to a range of 60 feet. Darkvision is black and white only, but it is otherwise like normal sight, and a fiend can function with no light at all.
Allegiances: All fiends have a primary allegiance to evil. Fiends may also have an allegiance to either chaos or law.
Weapon and Armor Proficiency: Fiends receive either Archaic Weapons Proficiency or Simple Weapons Proficiency as a bonus feat. They are proficient with their natural weapons and any weapon mentioned in their entries. Fiends noted for wearing armor gain the bonus feat Armor Proficiency with whatever type of armor they are accustomed to wearing (light, medium, heavy), as well as all lighter types.
Languages: Fiends can speak Abyssal (the language of demons) and a number of additional languages equal to their Intelligence bonus. Fiends with an Intelligence of 8 or higher can also read and write these languages.
Special: Fiends cannot be raised from the dead.
Fleshraker (Knife Fiend)
Bonus Feat: A fleshraker gains Archaic Weapons Proficiency as a bonus feat.
Damage Reduction 10/Ballistic (Ex): A fleshraker ignores the first 10 points of damage dealt by any nonballistic weapon.
Death Hunger (Ex): A fleshraker that goes 24 hours without killing a human suffers 1d4 points of Constitution damage. This damage cannot be restored until the fleshraker kills a human, at which point the ability damage heals normally.
Fire Resistance 20 (Ex): A fleshraker ignores the first 20 points of damage from any attack that deals fire damage.
Immunities (Ex): A fleshraker is immune to slashing and piercing weapons.
Wounding Weapon (Su): Any slashing weapon wielded by a fleshraker can inflict terrible wounds that bleed profusely. In addition to the normal damage the weapon deals, the target takes 1 point of damage that round and each subsequent round from bleeding. Multiple wounds from a wounding weapon result in cumulative bleeding loss (two wounds for 2 points of damage per round, and so on). A successful Treat Injury check (DC 15) or the application of any cure spell stops the bleeding. The weapon does not retain this ability outside the grasp of a knife fiend, although any bleeding wounds it has inflicted continue to bleed if the fleshraker is disarmed.
