Waveborn

Within you dwells a drop of pure elemental water, connecting you to the deep oceans, babbling brooks, and frigid waters of frozen lakes. How did you gain this power over the elemental waters? Did you inexplicably survive a shipwreck, awakening in the debt of a noble Marid, or did you drink from a stream flowing from the plane of water, awakening your power?

The lapping of waves, the spray of sea foam on the wind, the ocean depths, all of these call to you. Do you embody the life-giving properties of the gentle rain, or do you wield the overwhelming destruction of the great waves and floods?

Heart of Water

The pure elemental water within you has fundamentally altered your physical form. Starting when you choose this origin at 1st level, you gain the following features:

Curse of the Depths

Your watery spells carry a frozen curse. Starting at 1st level, when you deal cold damage to a creature, you can use your reaction to enhance the spell, covering one target in frost, reducing it's speed by a number of feet equal to five times your Charisma modifier (minimum of 5 feet).

This reduction lasts until the start of your next turn, unless a creature uses an action to scrape the frost off the target.

Watery Resilience

Beginning at 6th level, when you are hit with an attack, you can use your reaction to shift into a watery form, gaining resistance to any bludgeoning, piercing, and slashing damage the attack dealt, and immediately moving up to your full movement speed without provoking opportunity attacks.

You can use this reaction a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a long rest.

Shifting Form

The elemental water within allows you to move like flowing water. Starting at 14th level, you gain the following benefits:

Primordial Waters

Upon reaching 18th level, your body is permanently altered by the elemental water within you. As long as you are not incapacitated, when you are hit by an attack that is a critical hit, you can absorb the blow like a liquid, turning the critical hit into a normal hit.
