You push both hands forward to blast a searing beam of life-draining energy. This beam lingers for several seconds. During this brief period, you can point the beam in one direction as a 60-foot line, sweep it over a small area as a 60-foot cone, or spiral it around you as a 60-foot-radius circle centered on you. When the beam covers a wider area, each individual target suffers it for less time, and consequently takes less damage. Any target in range must succeed on a Dexterity saving throw to duck out of the way, or take damage based on the area selected:

60-Foot Line: 42 (12d6) necrotic damage

60-Foot Cone: 35 (10d6) necrotic damage

60-Foot Radius: 28 (8d6) necrotic damage

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, increase the necrotic damage by 1d6 for every slot level above 5th.
