The Desertborn

Imagine a figure old and fragile just strolling through a tough desert. Suddenly a giant purple worm emerges from the sands thirsty for fresh prey. Struck in fear you would imagine stands the figure but in the blink of an eye the dune under the figure's feets starts moving rushing the figure out of reach leaving the worm in disbelieve.

Summon the Desert

At 1st level, the sweltering desert within you begs to be brought forth. As an action, you can transform the area in 5 foot cube below you, provided the ground isn't made of water, metal, or wood, to sand.

The area this feature affects increases to a 20-foot-square at 6th level, 45-foot-square at 14th, and 90-foot-square at 18th level.

Defense of the Sand

Also at 1st level, if you are within a 10 feet of a 5-foot square of sand and you are targeted by a ranged attack, you can use your reaction to build a defensive wall. This wall automatically rises in the direction of the ranged attack, and provides you half-cover until the start of your next turn.

The Loving Desert

At your 6th level, you gain resistance to (fire or bludgeoning) damage, and you can spend 2 Sorcery points to use your Summon the Desert feature as a bonus action.

Additionally, when you use your Summon the Desert feature, you can extract up to 1 gallon of water from the terrain.

Echo in the Sand

At your 14th level, once per short rest you gain the ability as a bonus action to sense movement on and inside the sand. Therefor you need to concentrate on doing so. As long as the sand under your feet is dry you gain tremorsense up to 15ft for 1 minute.

Moving Dune

At 18th level, you have uttained mastery over the sands, and the very grains of the earth move to your will. When on or on top of sand, your speed increases by 20 feet, and you gain a 30 foot fly speed, as the sands lift you into the air.

Additionally, while standing on sand, you can summon a 10-foot radius sand disk within 20 feet of you. It must stay within 60 feet of you, or else it crumbles back into sand. It hovers 5 feet off of the ground, has a 30 foot speed, and can lift up to 500 pounds.
