Aspect of the Progenitor

You draw on the pure aspect of the progenitor of metallic dragons, firing a breath of pure platinum colored flames from your mouth in a 60 foot radius. All creatures within the area must make a constitution saving throw or take 8d8 force damage and become blinded and stunned for 1 minute. Additionally, if the target fails a save the next strike against the target has advantage. If the target succeeds on its saving throw it takes half damage and is only blinded for one round.

At Higher Levels. When this spell is cast using a 7th level spell slot or higher, the damage is increased by 1d8 for every level above 6th.
