Dark orb

You create a large black orb that seems to sap

away the light around it. The orb shoots forward in a

direction you choose, hitting every creature in a line 100

feet long and 5 feet wide. Each creature in the line must

make a Dexterity saving throw. A creature takes 8d6

necrotic damage on a failed save, or half as much damage

on a successful one.

At Higher Levels. When you cast this spell using a spell

slot of 4th level or higher, the damage increases by 1d6 for

each slot level above 3rd.
