Cone of Corruption

A blast of corrupted shards erupts from your hands. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 piercing damage on a failed save, or half as much damage on a successful one.

A creature killed by this spell gets entangled in corrupt vine that spread for 1d4 minutes that when touched you take 1d4 necrotic damage.     

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
