Using this spell the White Cloak buys success at the cost of their own self. Ravage is invoked just before the Mage makes any skill or attribute check; the Mage gains +2 on that roll. Each time the Mage uses this power they damage themselves within, gaining corruption at a rapid rate. Sigmata caused by this corruption take the form of wracking coughs, internal pain, leaking pus, and black bile. A Mage who over-uses this spell cracks open like a rotten fruit, spilling corruption into the soil.
