Cone of Destruction

Choose bludgeoning, piercing or slashing. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 damage on a failed save, or half as much damage on a successful one. Every casters manifestation is unique. Some may create clubs, arrows and daggers. Others might create lumps and shards of stone or glass. All such material disintegrates immediately after the spell is resolved.

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.
