The Resonance Cannon first appears in Book 6 as a devastating siege weapon capable of shattering protective barriers and structures with harmonic force waves. Throughout the later books, it evolves from a stationary fortress defense into a portable, script-enhanced device that can be wielded by individual sacred artists. Its core function—amplifying and focusing madra into concussive blasts—remains constant, but its scale, mobility, and integration with personal techniques mark a dramatic shift in how it is deployed.
