Your entire arm turns into a black and green veined monstrosity as a beam of sickly green energy flies from your outstretched hand in a 5-foot wide, 60-foot long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 6d10 necrotic damage and for the spells duration takes an additional 2d10 at the beginning of their turn. On a successful save, the creature takes half damage and no additional damage for the duration. If at any time of the duration a creature falls to 0 hit points from damage of this spell they are instantly killed and cannot be resurrected unless by a wish spell.

You can create a new line of sickly green energy as your action on any turn until the spell ends.

This spell does not effect the undead or constructs.
