Eldritch Ray

You extend your palms forward and blast a ray of pure eldritch energy. All creatures in a 15 foot cone in front of you must make a Dexterity saving throw or take 3d6 force damage, be pushed 5 feet back and fall prone. If they succeed the saving throw they take half damage and suffer no additional effects.

At Higher Levels: When this spell is cast with a spell slot higher than 1st, it deals an extra 1d6 damage.
