This wing of the library is currently under construction. Please excuse our pixie dust.
Stone magic is the art of strength, stability, and the earth beneath our feet. Its practitioners command rock, soil, and mineral—raising barriers, reinforcing defenses, shifting terrain, and turning the ground itself against their enemies. Stone spells favor resilience and battlefield control, rewarding mages who would rather reshape the fight than simply overpower it.
At its gentlest, Stone strengthens weapons, armor, and the foundations upon which we stand. At its most violent, the earth cracks, trembles, and rises against those foolish enough to challenge it. Stone does not hurry. It simply endures until everything else gives way.
