The sixth level marked a significant threshold for mages. It was the number of magic circles in a spell that determined its mana capacity, but the resulting power wasn't merely additive—it was exponential. This was noticeable at lower levels, but the true impact of this growth became undeniable at the sixth level.
While a fifth-circle spell might be capable of destroying a home or attacking a group of people, a sixth-circle spell could lay waste to an entire town or village. It was the point where magic's destructive potential began to escalate, where large-scale devastation became a terrifying reality. Even in healing magic, the difference was stark. At the sixth level, spells gained the potency to heal entire groups instead of just individuals. It was the magic of war.
