The character can, with a touch, alter a person's biochemistry to react violently with his immune system, rendering him shudderingly ill.
The target may make a saving throw (14+ PE bonuses apply). If he fails, his body changes color (pick one at time of power creation) and he becomes violently ill (character becomes stunned for the rest of the melee round with a 45-PE % chance of vomiting. He loses one attack per melee, and -3 to all combat skills, -25% to all other skills and halve spd for another 1d4melee rounds).
Furthermore, anyone the target touches must also make the same saving throw or pass the illness onward (and anyone they touch etc..).
The character is immune to his own contagious stain, and can reverse it by touch on a target.
The character can make a total of 2 contagious stains per melee round, each one requiring 2 actions.
