Dragon's Blood Rend

You channel the power of dragons to project a stream of boiling blood in a straight line in front of you. Each creature in its path must make a Dexterity saving throw. On a failed save, they take 6d10 piercing damage and 5d6 fire damage. 

Additionally, you can choose to target a creature's blood within the spell's range instead of a creature itself. If the target has blood, the spell ruptures the creature's veins, dealing 8d10 damage to it. The targeted creature must make a Constitution saving throw to avoid being stunned until the end of the caster's next turn. 

The spell’s damage increases by 1d10 for each spell slot level above 5th, and the damage to a creature's blood increases by 1d10 for every two spell slots above 5th.
