Seastone Scattershot Mortar Cannons

Created by R_Nixon

Forged by the legendary Blue Builder Kaneshiro, these devastating naval weapons represent the pinnacle of anti-Devil Fruit engineering. Each cannon fires ammunition composed of meticulously packed seastone fragments bound together with a heat-sensitive adhesive that fractures upon discharge, transforming into a devastating barrage of shrapnel that descends upon enemies like a supernatural downpour. The seastone's inherent properties—both its diamond-like resilience and its supernatural ability to suppress Devil Fruit powers—make these cannons invaluable against supernatural adversaries who would otherwise dominate conventional warfare. The explosive dispersal pattern ensures that even evasive targets struggle to escape the wide radius of effect, while the seastone's nullifying essence strips away magical defenses and abilities upon impact. Kaneshiro's strategic connections to Ryugu Kingdom and Fish-Man Island provide a steady supply of rare seastone sediment, allowing continuous production despite the material's scarcity throughout the world. These cannons fundamentally altered naval combat, granting the Twilight Pirates a decisive advantage that conventional forces struggle to gain.
