Eldritch Communion

Your Eldritch blast can now target allies to heal them. You can use any of your EB casts to target an ally. In doing so you automatically hit them and instead of dealing damage you heal them instead, with an additional D6 added to the D10.

You can also add the effects of any eldritch invocations on the spell if you wish. 

Eldritch blast can be used this way PB+1 per long rest.
