Blood Manipulation: Supernova

Compress your blood into an orb between your hands and send it out in front of you. The orb will explode either instantly after reaching its target, after 1 round or on using a reaction to detonate it ,dealing 6d10 Necrotic Damage in a 10 foot range around the orb upon its explosion. Any creature caught in the area must roll a DC15 Dexterity save, on a successful save, the target takes half damage. 

If you choose to wait until detonation, anyone who fails the save will have the Poisoned condition applied
