Saṁśuddhatāvaya
Saṁśuddhatāvaya is a level four abjuration spell with a duration of ten minutes that is cast upon the self.
Once cast a purifying energy radiates preventing you from being poisoned, deafened, blinded, charmed, or stunned by magical energy. But these types of injuries can still occur by conventional means. The most powerful use of the spell is its overall protection against the transmission of disease from virus, spore, bacteria, and parasite. Therefore, the American Medical Association has made Saṁśuddhatāvaya as common and as required as hand washing for examining physicians.
