Half-Fiend
"Half-fiend" is an inherited template that can be added to any living, corporeal creature with an Intelligence score of 4 or more and nongood alignment (referred to hereafter as the base creature). A half-fiend uses all the base creature's statistics and special abilities except as noted here.
Size and Type: The creature's type changes to outsider. Do not recalculate Hit Dice, base attack bonus, or saves. Size is unchanged, unless the parent Fiend is Huge or larger, and the base creature is Large or smaller. In that case increase Size by 1 category, and adjust physical Ability Scores, Natural AC Bonus, and base damage for attacks as per the Monster Manual. Half-fiends are normally Native Outsiders.
Hit Dice: Unchanged.
Speed: Varies, see below.
Armor Class: Varies, see below.
Attacks: Varies, see below. The base creature gains natural attacks the same of the Fiendish parent if it does not already have them.
Damage: Varies, see below.
Special Attacks: Mention whether or not the base creature retains any of it’s special attacks or gains any new ones here.
Special Qualities: Retains Special Qualities of the base creature, plus gains the following depending on Fiend Type:
Demons (Tanar'ri) get: Darkvision 60 ft., Immunity to electricity and poison, Energy Resistance 10 (acid, cold, fire), DR 5/Cold Iron or DR 5/Good, Spell resistance equal to creature's HD + 10 (maximum 35), and your natural weapons are treated as magic weapons for the purpose of overcoming damage reduction.
