7th-level Necromancy

Casting Time: 1 action
Range: 60 feet
Components: V, M (a bit of rope from a noose)
Duration: Concentration, 1 minute

All creatures within the area of this spell begin to suffocate immediately, gasping for air. Choose a point within view in range. All creatures within 20 feet of that point must make a Constitution saving throw. On a success, they are unaffected by the spell.

On a failure, the creature begins to choke, taking 6d6 necrotic damage per turn. They may repeat the save at the end of each of their turns. While suffocating, all attacks against the creature have advantage, and all of the creature’s own attacks have disadvantage. Furthermore, the creature’s speed is halved, and the effect does not end if the creature leaves the radius of the spell.

If the creature is still affected by the spell after one minute has passed, they fall unconscious.
Usable by: Cleric, Druid, Sorcerer, Warlock, Wizard
