Channel Divinity

When you use Channel Divinity, you can choose one of the following:

• Empower Healing. Sacrifice hit points equal to twice your cleric level. For every 2 hit points you sacrifice, add +1 to the healing of one cleric spell you cast this turn.
• Pierce Resistance. When you deal necrotic damage with a cleric spell, you can take damage equal to your Wisdom modifier to ignore necrotic resistance on the affected creature.
