Aquatic Mastery

You tap into the deepest wellsprings of water magic, becoming a conduit of the element itself. For the duration, the following effects occur:

1. Aqueous Form: Your body transforms into a living, fluid state. You gain resistance to all damage, and you can move through spaces as narrow as 1 inch wide without squeezing. You can also breathe underwater.

2. Torrential Downfall: Your healing spells heal an additional 3d8 health. Additionally, you can make a ranged spell attack to shoot jets of pressurized water, dealing 6d10 cold damage to a target within 60 feet.

3. Tidal Surge: Once per turn, as a bonus action, you can release a wave of water in a 30-foot cone. Creatures in the area must make a Strength saving throw or be pushed 20 feet away and knocked prone.

At Higher Levels: When you cast this spell using a spell slot of 10th level or higher, the additional damage from Torrential Downfall increases by 1d8 and the damage from Tidal Surge increases by 2d10 for each slot level above 9th.

Note: Aquatic Mastery is a spell of unparalleled water manipulation. It grants the caster incredible defensive capabilities, great healing abilities and ranged attacks, and the ability to control water with exceptional force. This spell allows a high-level caster to become a formidable force on the battlefield, harnessing the power of the sea itself.
