Ōnami Kaitai-tama

Hadō #94. Ōnami Kaitai-tama (大波解体球, Great Wave Dissolution Sphere) is a Spell.

Overview
Ōnami Kaitai-tama starts with the coalescence of a sphere of water above the user's hand. This orb grows and grows as the user finishes the incantation until it ends up being around ten feet in diameter.

Upon completion of the spells, a wave of spiritual water rampages forth from the sphere, covering all of creation with its rampaging current. Most beings and structures will collapse under the power of the waves, but those that survive will experience a different hell as these waters erodes away at their very spiritual being. The flow of the waves is not the main threat of this spell, but the loss of self as the water washes away all before it.

Incantation
"God of Gentle Rains. Demon of Ferocious Storms. Bloody rivers sweep all away. Return all to the Primordial Sea. Seven Seas, Five Oceans. All comes from the Sea, all shall return to it. Thy's lost mother reclaims her children. Ocean's fury, come forth and send all back to the Abyss!"
