Ludic Sanctuary

Water Spirit Magic: Ludic Sanctuary (水精霊魔法『』) is a water-based Spirit Magic spell.

Description
The user summons a pillar of swirling water around a target, lifting them high into the air. The user then pulls in water from their surroundings, combines it with Undine and the pillar, and creates a massive body of water. Large natural mana arrays are placed above, below, and around the body of water.

The target is trapped within the mass of water, and their magic is diluted and weakened due to being submerged in water. Alternatively, the user's allies who also use Water Magic have their power boosted.
