Blood Magic

Draw upon your own life force to add more vigor to your attacks, and more focus to your spellcasting. The more you call upon this power the greater the cost, the greater the strength.

As a bonus action, draw your own blood for 1d4 necrotic damage as you draw upon your own life force to add an additional damage dice to each damage type you deal for the next 2 rounds. Subsequent uses of this feat add an additional 1d4 necrotic damage to themselves, also adding an additional dice to bonus damage gained from use of this feat, until a long or short rest.
