Dark Creature

Dark Creature (CR +0 or +1)
Dark creatures are native denizens of the Plane of Shadow, and generally have a dark gray or deep purple coloration. A dark creature’s CR increases by 1 only if the base creature has 5 or more HD.

Rebuild Rules: Senses gain darkvision; Defensive Abilities gains DR and resistance to cold and electricity based on its Hit Dice, as noted on the table below; SR gains SR equal to its new CR + 5.

Hit Dice DR Resist Cold and Electricity
1–4 5
5–10 5/magic 10
11+ 10/magic 15

Shadow Blend (Su): In any illumination other than bright light, a dark creature blends into the shadows, giving it concealment (20% miss chance). A dark creature can suspend or resume this ability as a free action.
