This rare and dreaded power takes psychic domination to its its final expression. The psyler makes an opposed willpower test against the target (in this test the psyker suffers a -10 penalty). If the psyker wins, the target’s body is completely under his control. The psyker’s mind leaves his body behind to take over the victim’s body completely, whilst the victim’s consciousness is suppressed into a nightmarish dream state. The psyker’s own body is vulnerable during this time, as if he were in a deep sleep. The psyker may end the power at any time but suffers 1d5 fatigue levels for doing so.
The possessed target retains is prior physical characteristics (weapon skill, ballistic skill, strength, toughness, and agility), but its mental characteristic (intelligence, willpower, and fellowship) are those of the psyker. The psyker in control of the body may use either his skills or the target’s at a -10 penalty. Any action deemed suicidal forces another opposed willpower test to try and break the hold. However, the target is now suffering a -10 penalty rather than the psyker. Should the target’s body be killed, the psyker’s consciousness is hurled violently out of the dying bessel, suffering 1d5 wounds (these wounds bypass all defences) and 1d10 insanity points.
If the distance between the psyker and his victim reaches beyond the technique’s range the link is severed, and the psyker returns to his own body whilst suffering 1d5 fatigue levels in the process.
