Air Removal (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a bit of earth from the Plane of Air)|
|Duration:||Concentration, up to 1 minute|
You remove breathable air from within the body of a creature within range, and prevent any air from entering for the duration. The target must make a Constitution save. Air elementals, or other creatures made primarily of air, have disadvantage on this saving throw. On a failed save, the creature takes 10d8 necrotic damage, and this spell continues if the creature has a need to breathe. On a successful save, the creature takes half as much damage, and the spell ends.
At the end of your next turn, the creature must succeed on another Constitution saving throw or begin to suffocate, as it has run out of breath. It can repeat the saving throw at the end of each of your turns, ending the spell on a success.
