Though it was not a lot of the substance, any of it was enough to corrupt even the most gentle and loving minds. In Max's case, the pitiful life of a lesser may have saved his own; had he sampled from something larger and more intelligent, the amount of magical presence may have been enough to kill him. The goo is highly poisonous, both to the mind and to the body...
However, due to the lesser's weaker magic, it would become a mild corruption, slowly eating away at his mind until he no longer is himself. It will manifest first in his eyes, giving them a neon-green sheen; and then in his veins, turning his blood to oily sludge; and finally in his overall appearance, making him sickly and frail, and nearly rabid at first glance with excessive drooling and occasional bouts of snarling or snapping.
Max will suffer the following consequences:
— Overwhelming vertigo
— Toxic saliva, even to himself
— Vomiting if too much toxic saliva is swallowed; he may dilute with water
— Loss of self awareness
— Loss of control when using magic
— Eventually, in 13 Cycles, he will be completely fueled by chaos and no longer be himself
— If Max rolls a 1 or 20 using magic, he may die. Request GM to post for save possibilities, but rolls are not guaranteed of course!
It is unknown what may cure Max, if anything. His fellow Gembounds may aid him but it will not be clear to others what caused this change unless he is able to tell them himself.
