Entropic creatures dwell on the Negative Energy Plane. In addition to large quantities of undead, entropic creatures ideally adapted to the negative energy environment inhabit the plane.
Creating An Entropic Creature
"Entropic" is an inherited template that can be added to any corporeal aberration, animal, dragon, fey, giant, humanoid, magical beast, monstrous humanoid, outsider, plant, undead, or vermin (referred to hereafter as the base creature).
An entropic creature uses all the base creature's statistics and abilities except as noted here.
Size and Type: Unless the creature was undead, its type changes to outsider. Do not recalculate the creature's Hit Dice, base attack bonus, or saves. Size is unchanged. The creature also gains the extraplanar subtype.
Special Attacks: An entropic creature retains all the special attacks of the base creature and also gains the following special attack.
Negative Energy Ray (Su): An entropic creature can fire a ray of negative energy once every 1d4 rounds with a range of 60 feet. With a successful ranged touch attack, an entropic creature infuses a target with points of negative energy damage equal to 1d4 + its Cha modifier. This attack damages living creatures and heals undead.
Special Qualities: An entropic creature has all the special qualities of the base creature, plus the following special qualities.
- Limited Spell Resistance (Positive Energy) (Ex): An entropic creature has spell resistance equal to 15 + Hit Dice (maximum 35) against any spell or spell-like ability that uses positive energy, including cure spells.
- Negative Adaptation (Ex): Entropic creatures do not lose hit points or need to make Fortitude saves due to being in a negative-dominant environment.
- Negative Energy Aura (Su): Any living creature within 10 feet of an entropic creature loses 1 hit point per round due to the aura of negative energy surrounding it. Characters with immunity to negative energy effects, as well as other entropic creatures, are not affected by this aura. If conscious, an entropic creature can repress this aura as a standard action, but takes 1 point of Strength damage for each full minute that the aura is inactive. The aura is always functioning while an entropic creature is unconscious.
Outsider Traits: An entropic creature cannot be raised, reincarnated or resurrected (though a limited wish, wish, miracle, or true resurrection spell can restore life). It has darkvision out to 60 feet.
Turn Resistance (Ex): An undead entropic creature has +4 turn resistance.
Abilities: Increase from the base creature as follows: Constitution +2, Charisma +2. Intelligence is at least 3.
Environment: The Negative Energy Plane or same as the base creature.
Challenge Rating: 3 HD or fewer, as the base creature +1; 4 to 7 HD, as the base creature +2; 8 or more HD, as the base creature +3.
Level Adjustment: +2.
