Desiccate

Your touch draws the moisture from living things. Make a melee spell attack against the target. On a hit, the target takes 1d10 necrotic damage and it can't regain hit points until the start of your next turn. If your target is a plant, it is vulnerable to this damage.

This spell has no effect on undead or constructs.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
