Clever Corruptor. Using its power to assume a pleasing or innocuous form, a tripurasura wanders the world, seeking pious mortals to corrupt. When it encounters a promising spellcaster (typically one who has some sort of link to a church or religion, but not necessarily a divine spellcaster), the tripurasura presents itself as an apprentice, pilgrim, or other type of curious student eager to learn from the spellcaster. The tripurasura keeps its true nature and its powers hidden and seeks opportunities to steer its "master" away from decisions it might have made in good conscience to acts that promote the collapse of religious belief, faith, and society. When, as it inevitably does, the wayward spellcaster runs afoul of justice or is confronted by those seeking revenge, the tripurasura fades away to watch the final stage of the spellcaster's fall from grace, then seeks a new victim in another city or region.
