You draw a moisture from the every creature within a 30-foot cube which is centered on a point that you chose within a specific range. Each and every creature in that specific area should make a constitution saving throw. Actually, the constructs and the undead are not affected and even the plants and and also the water elementals make this saving throw with the disadvantage. So a creature can take 10d8 necrotic damage on a failed save or else half as much damage on a successful one.
