When you choose this fight club at 3rd level, you gain the ability to channel divine energy directly from your deity, using that energy to fuel magical effects. You start with two such effects: Channel Divinity: Fists of Faith and Channel Divinity: Grace of the Gods.
When you use your Channel Divinity, you choose which effect to create. You must then finish a short or long rest to use your Channel Divinity again. Some Channel Divinity effects require saving throws. When you use such an effect from this class, the DC equals 8 + your proficiency bonus + your Wisdom modifier.
Beginning at 11th level, you can use your Channel Divinity twice between rests. When you finish a short or long rest, you regain your expended uses.
Fists of Faith. You use a bonus action and offer up your hands to the will of the divine. For the next minute, your unarmed strikes score a critical hit on a result of 19 or 20.
Grace of the Gods. As a bonus action, you offer a prayer up to the gods and their divine protection surrounds you. You gain 1d10 + your pugilist level in temporary hit points. While you have any temporary hit points from this ability, you have resistance to all damage. You lose all temporary hit points granted by this ability after 1 minute.
