Brew Venomous Blood
Description: While the some regarded poison as foul, some of the modern age mages use it in the defense of their homes and traditions. By boiling together a foul mixture of blood, salt, yeast, earth, iron, ice and some drops of snake venom under invocations of the powers of death, they create a potent and untraceable poison. The poison can be applied in food or drink,placed on weapons or even on surfaces. The poison will seek out the weakest point of the victim and make him very sick or kill him.
System: The poison works as an infection or other disease, completely coincidental. Typical effects can be heart attacks, allergic reactions or food poisoning. It will find the weakest point in the body of the victim and then strike. The arête successes are equal to lethal damage caused.
