Dehydrate

You choose a target you can see within range and afflict it with a crippling condition that deals 1d4 + 1 per spellcasting ability modifier constitution damage. The target also gains one level of exhaustion. Oozes, plants and water elementals are especially vulnerable to this – making their saves with disadvantage and on a failed save, rolling 1d8 instead of 1d4 for damage adding the relevant bonuses.
