Volley of Thornes

You project a blast of sharp thorns in a 60-foot cone from your outstretched hand. Each creature in the cone takes 6d6 piercing damage or half damage with a successful Dexterity saving throw. A target whose AC (including cover bonuses) is equal to or greater than the spellcaster’s save DC takes half damage from the spell normally, or no damage with a successful Dexterity saving throw. Enhancement: For each spell slot used higher than 3rd level, the damage increases by 1d6.
