Generic, Text: Boiling Blood

At 14th level, you gain the ability to cause irregularities in enemies' blood from a distance. You may use this feature as an action. A creature with blood (as ruled by the DM) within 60ft of you must make a Constitution saving throw. The target takes 5d10 necrotic damage on a failed save or half as much on a successful one. You may do this a number of times equal to your Constitution modifier, with a minimum of 1. You regain your uses after a long rest.
