Noxious Pulse

7th-level necromancy

Casting Time: 1 action

Range: Self (30-foot radius)

Components: V

Duration: Instantaneous

You beckon forth a surge of harmful, crippling dark energy that pulses from you. Each creature you choose within 30 feet of you must succeed on a Constitution saving throw or take 6d12 radiant or necrotic damage (your choice) and has disadvantage on attack rolls until the end of their next turn. A creature that succeeds on its saving throw takes half as much damage and does not have disadvantage.

At Higher Levels. When you cast this spell at 8th level or higher, the damage increases by 1d12 for each slot level above 7th.
