SKILL-DEMONIC-TRANCE

If one offers his body as a willing offering for a demon, then a demon may accept and live within his body for a time in a symbiotic relationship. The demon gains limited control of the offering's body, and in return the offering will gain some aspects of the demon.

Some benefits to the offering include increased combat ability, an increased ability to focus as demons are quite single-minded, and also a slightly increased resistance to harm. However, there are drawbacks, and some of the more aggressive, evil tendencies of the demon will emerge as well.

Housing a demon is quite traumatic to the offering, and he will find his body unable to hold the demon for long, and in fact, a weak vessel may be destroyed by the demon.
