Disfigured

The Mountainbreaker struck the wall. The force traveled through Eiro's arm and into his body. He was able to weaken the impact by fusing his body with water magic, instead deflecting the energy back into the hammer perfectly in time to strengthen his second strike. And his third and fourth. Each consequent strike was stronger than the one before it, and it didn't take long until the wall, originally strenghtened and kept together by the supernatural force of the Dungeon Map, wasn't able to resist the supernatural damage anymore. Even without the system's assistance, as the system was unable to acknowledge what Eiro was doing due to the invisibility potion, the Mountainbreaker's arcane force was powerful enough to damage the physicality of the wall.
