Wrath of the Blood God

You look to the stars, closing your eyes you look back down. Hatred fills you. You slit your wrist and stab yourself and blood flows out of and around you. You look to those around you, opening your eyes they're blood red and glowing. You let out a possessed scream and unleash a pulse of blood, then you run at the speed of light slashing everything you come into contact with, even allies. All creatures around you take dage from the pulse and any creature in your line of sight is what you slash. The blood you spill flows around you. When you're done it is a blood bath and all that blood swirls around you. You now can cast up to 5 +the creatures you slash, blood spells without drawing blood. If a creature is incapacitated they become a blood shade.
