Blood Spew

You extend your hand towards a creature within range, spewing forth a foul stream of necrotic blood. Make a ranged spell attack. On a hit, a creature suffers 1D10 Necrotic damage and must make a Constitution saving throw. On a failed roll, the creature is poisoned until the end of its next turn. Succeeding the saving throw causes no additional affects. The drop of blood is taken as a toll from the user of this cantrip, causing 1 Necrotic damage to the caster.

At Higher levels: Increases the damage dice and damage taken by 1 at 5th (2D10, 2 damage taken), 11th (3D10, 3 damage taken) and 17th (4D10, 4 damage taken) level.
