As a Magic action, you present your Holy Symbol and expend a use of your Channel Divinity to evoke healing energy that can restore a number of Hit
Points equal to five times your Cleric level. Choose Bloodied creatures within 30 feet of yourself (which can include you), and divide those Hit Points among them.
This feature can restore a creature to no more than half its Hit Point maximum.
As a Magic action, you point your Holy Symbol at another creature you can see within 30 feet of yourself and focus divine energy at it.
Roll 1d8 and add your Wisdom modifier. You either restore Hit Points to the creature equal to that total or force the creature to make a Constitution saving throw. On a failed save, the creature takes Necrotic or Radiant damage (your choice) equal to that total. On a successful save, the creature takes half as much damage (round down).
You roll an additional d8 when you reach Cleric levels 7 (2d8), 13 (3d8), and 18 (4d8).
