Mystic Glass Shards

Mystic Glass Shards
Level 4 - Evocation

Casting Time: 1 action
Range: 30 feet cone
Components: V, S, M (a piece of colored stained glass)
Duration: Instantaneous

You conjure a massive illusory pane of glass in front of you and shatter it violently with your will. A torrent of sharp shards rains down in a 30-foot cone. Each creature in the area must make a Dexterity saving throw.

On a failed save, a creature takes 8d6 force damage, or half as much damage on a successful one. Additionally, the ground in the area is littered with residual shards, becoming difficult terrain until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
