Disciplines of The Orang Minyak - Slippery Oily Psychic Path

Before the fires of the Atomic Wars on Old Earth the path of the Orang Minyak was developed. The name  literally means oily man. According to legend the orang minyak was a man who was cursed in an attempt to win back his love with magic. The reality is far worse & far more sinister. Orang Minyak is a psychic  who uses ancient twisted rites who gives his soul over to a type of rare planar demon. This demon demands a sacrifice of the humanity of the psychic. The user is possessed by the demon who modifies the fool's body to produce the tar like liquid.This stuff comes from the gelled evil & cast off negativity of  the psychic. The stuff comes from within the pores of the user.As well from outside of the body which draws the negativity within. 

The oily coating itself offers several advantages. The first is that the monster can,"Hide in shadows as a thief". The second is that all attempts to catch the creature are at a -1 to -2 depending on the character's actions.Due to the use of naturally occurring black grease, it makes the orang minyak hard to catch, as pursuers would not be able to hold on to him.
