All creatures marked by you become unmarked, and the target becomes marked by your Oath of Emnity until the enemy is defeated, or until you are reduced to 0 hit points by that creature. While the target remains marked by your Oath of Emnity, you always know its hit points, condition, and its direction and distance away from you. While a creature is marked by your Oath of Emnity, you may not mark any other creatures.
Whenever you attack the creature marked by your Oath of Emnity, you gain a feat bonus to your attack roll equal to your Wisdom modifier, and the attack is a critical hit on a roll of 19-20. Each time you miss the target, the attack bonus increases by +1, to a maximum bonus equal to your Wisdom modifier plus your Charisma modifier.
At each even level, you may choose a new at-will Prayer from this class feature or any of your other class features, or training in a proficiency of your choice.
At each odd level, you may choose a new ranked Prayer from this class feature or any of your other class features, or may choose a new class feature from your class.
The next time a creature attacks using this weapon, the attack gains a +1 feat bonus and deals additional damage equal to your magic damage bonus if it hits. The damage type is determined by your Faith.
