Had a scene in my head where a person lured some people into the desert but then tried to enslave them. The captured turned the tables and dried their capture out using spells to get water and escape. Let’s make that happen!

Desiccate

2nd-level transmutation

Casting Time: 1 bonus action
Range: touch
Components: V, S
Duration: Concentration, up to 1 minute

The touch a creature solidly with your hand and begin to pull the water out of them as water flows from them out into the area into a container of your choice within five feet. Make a melee spell attack against a creature within your reach as an action. On a hit, the target takes 2d8 fire damage, and for each hit point you drain, you gain 1 gallon of water that you can float to location within 5 feet. Until the spell ends, you can make the attack again on each of your turns as an action.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 3rd.
