Promethean

The "promethean" template is an acquired template that can be added to any living corporeal creature with an intelligence score (except constructs, elementals, oozes and plants). A promethean creature has all the base creature's characteristics except as noted here.

Type: Animals become magical beasts. Humanoids become monstrous humanoids.  Statistics derived from any racial HD it has change accordingly.
Speed: The base creature's movement speeds increase by 50%.

Armor Class: Natural armor improves by +10.

Special Qualities: A promethean retains all the special qualities of the base creature and gains those described below.

  Maximized Hit Points

  Blindsight 500 ft.

  Darkvision 1,000 ft.

  Damage Reduction 10/epic

  Fast Healing 10

  Spell Resistance 12 + CR
  Mettle (Ex): A promethean can resist magical and unusual attacks with great willpower or fortitude. If one makes a successful Will or Fortitude save against an attack that normally would have a lesser effect on a successful save (such as any spell with a saving throw entry of Will half or Fortitude partial), he or she instead completely negates the effect.

  Regeneration 1 (Ex): A promethean takes normal damage from fire and negative energy. A promethean may reattach a severed extremity instantly by holding it to the stump, and may regrow a severed limb in 5d6 rounds.

  Resistances (Ex): A promethean's resistances to acid, cold, electricity, fire and sonic energy improve by 20.

  Immunities (Ex): Prometheans are immune to involuntary polymorph effects, petrification, or any form-altering attack. They are not subject to death from massive damage, energy drain, ability drain, or ability damage. They are immune to involuntary mind-affecting effects.

  Telepathy (Su): Prometheans can communicate telepathically with any creature within 1,000 feet that has a language.
