Terrain Effect: Whirlpool Zone (地形効果渦潮帯 Chikei Kōka Uzushio-tai) is a Terrain Effect Magic Spell.
To activate this spell, the user raises both of their arms over their head, pointing them straight up towards the sky. This action creates a torrent of water that surrounds them, circling in a fashion similar to a tornado. From there, the water can be manipulated to flow outwards from the user in huge waves, engulfing anything in its path or flooding an entire area.
