Death beam

As you utter your words of death a beam of darkness streaks from your hand to 1 target of your choice within range. Make a ranged attack roll against the target with advantage if the target’s alignment is anything but neutral. On a hit the target takes 20d10 necrotic damage and has disadvantage on all saving throws and attack rolls for 1 minute. In addition the target cannot heal for the next 24 hours. If the first attack hits you can cause the targets life force to leap from the target to strike another target. You do not have to roll to hit with this attack. The second target suffers the damage but not the side effects. You can cause the life force to jump from the one target to an another target a number of times equal to your proficiency bonus, each one suffering the same effect as the second target.
