Create Aether

You call upon the powers of your deity, sacrificing a portion of your health to create an orb of bright light. Using an action you summon this orb and take 1d6 points of damage and reduce your total health by that much for the duration. Every turn after you can use your bonus action to heal a creature of your choice for 1d6+ your spell modifier health within line of sight. This spell increases to 1d10 at level 8 and 1d12 at level 15.  This spell persists until concentration drops or you fall unconscious.
