Sea Blast (Japanese: 水竜破シーブラスト, Kanji translation: Water Dragon Rend, Romaji: shīburasuto) is an offensive spell belonging to water shamanistic magic. In order for this spell to function, the caster must have his/her hand placed on a surface of water. The spell causes a large wave to appear, which could easily capsize a medium-sized ship. Sea Blast cannot be used underwater.
