Pious

You learn to channel the divine energy from a deity (or group of deities) of your choice. If you already have the Channel Divinity feature, you gain one additional use of it. Otherwise, you gain the ability to use Channel Divinity once. Once used, you can't use Channel Divinity again until you finish a long rest. 

Choose one Divine Domain from the cleric class. You can use your Channel Divinity to fuel one of the following magical effects from the cleric class: Turn Undead, Harness Divine Power (only if you have the Spellcasting feature) or a Channel Divinity option available to your chosen domain at 2nd-level.
