Blood Beam

Fire out a beam of compressed blood from your hands at an area. After summoning the mote of blood and clasping your hands over it, you chant until your next turn to imbue it with power. On your next turn, the beam fires at wherever you aimed it, imposing a dexterity check that upon failiure, deals 2D12 piercing damage to anything in its path. This beam continues to fire for 2 rounds, during which you use your action to shift the direction of the beam by 5ft. If a creature ends it turn in the radius of the beam, it takes 2D8 piercing damage.

At higher levels: Whenever you cast Blood beam using a spell slot of 3rd level or higher, the damage increases by 1D12.
