Vengeful Spirit

You expel a part of your soul to damage enemies within a 60ft range. You must target an enemy, then sacrifice a minimum of 1hp to send out a ball of soul energy that explodes in a 10ft radius to damage enemies for 3D6 force damage. When casting this spell, you can choose to sacrifice more points of HP to increase the damage modifier of this spell to a maximum of +10 ( which would cause players to lose 11 health).

At higher levels

The spell gains one extra D6 of damage for every spell slot after 3rd level.
