At 1st level, you gain the ability to manipulate the line between life and death. When you cast a spell that restores hit points to a living creature currently at 0, treat any dice rolled as having rolled their maximum result.
In addition, if you have the Spare the Dying cantrip, it can be cast a bonus action.
Starting at 2nd level, you can use your Channel Divinity to mark another creature's life force for termination.
As and action, you touch a creature. The next time that creature takes damage from a spell or attack from you or an ally, it is vulnerable to that spell or attack's damage. If the source causes multiple types of damage, the creature is vulnerable to all of them.
This vulnerability applies only to the first time the creature is attacked and then ends.
If the creature has resistance or is immune to a type of damage, it instead loses its resistance or immunity against that spell or attack until it is next attacked.
As an action, you present your holy Symbol and speak a prayer censuring the Undead. Each Undead that can see or hear you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.
A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.
Starting at 1st level, you gain an innate sense of creatures whose existence is an insult to the natural cycle of life. If you spend 1 minute in uninterrupted contemplation, you can determine the presence and nature of undead creatures in the area. This detection extends up to 1 mile in all directions.
You learn the number of undead and their distance and directions from you. In addition, you learn the creature type of the undead in that area that has the highest challenge rating.
Once you use this feature, you can't use it again until you finish a long rest.
