Draining Storm

You reach up your hands above your head as tendrils of Necrotic energy shoot forth from your fingertips. All creatures in a 60 foot radius must pass a Constitution Saving Throw DC13 or take 1d10 Necrotic Damage and become stunned for 1 round. You are healed for the total amount of damage dealt this way to creatures. This can only be used once per long rest. 

At level 9 this spell deals 3d10 Necrotic Damage instead.
