A fleshvigor looks like the base creature, although its mouth and teeth are larger, and its skin often has a flushed or fevered appearance. Fleshvigors behave just like normal undead of the base creature's kind.
Creating a Fleshvigor
"Fleshvigor" is an acquired template that can be added to any non-skeletal corporeal undead, referred to hereafter as the base creature. A fleshvigor uses all the base creature's statistics and special abilities except as noted here. An undead can acquire the fleshvigor template through a magical process; fleshvigor undead that can create spawn make spawn of the appropriate type with the fleshvigor template (so a fleshvigor ghoul creates fleshvigor ghoul spawn, and so on).
Armor Class: Natural armor improves by +2.
Attack: A fleshvigor retains all the attacks of the base creature and also gains a bite attack if it does not already have one.
Damage: If the base creature did not have a bite attack, use the damage value appropriate for its size as shown on the following table.
Special Qualities: A fleshvigor retains the special qualities of the base creature and gains the following special qualities.
Cannibalistic Healing (Su): Fleshvigors draw power from dead bodies they eat. As a full-round action, a fleshvigor may devour the flesh of a dead creature two or more sizes smaller than itself, leaving nothing but bones. Eating a creature one size smaller requires 5 rounds, and a creature the same size requires a full minute. Upon finishing its meal, the fleshvigor heals 5 hit points for every racial Hit Die of the consumed creature (not counting class levels, so a 5th-level human fighter counts as a 1-HD humanoid for this purpose); creatures of less than 1 HD heal the undead only 1 hit point. This healing cannot put the fleshvigor above its normal hit point total. The fleshvigor also gains fast healing for 5 minutes after using this ability. A fleshvigor cannot eat a creature larger than itself in this manner, nor does it gain any healing from consuming the flesh of such a creature.
Eating in this manner is an extraordinary ability, but the healing derived from the act of eating is a supernatural effect. After a meal, a fleshvigor's ruddy color visibly increases. Unintelligent fleshvigors (such as fleshvigor zombies) automatically fall upon and devour dead bodies in their vicinity as soon as combat ends.
A creature consumed by an undead with this ability and the spawn ability normally will not rise as an undead, as there isn't enough material left to form a creature of the spawning undead's kind. Likewise, they cannot be raised by a raise dead spell because the body is not whole enough to support life. Greater life-restoring magic (such as resurrection) works normally.
Abilities: Increase from the base creature as follows: Str +2.
Feats: Fleshvigors gain Weapon Focus (bite) as a bonus feat.
Challenge Rating: Same as the base creature +1.
Level Adjustment: Same as the base creature +1.
