Strength of the Grave

Starting at 1st level, your existence in a twilight state between life and death makes you difficult to defeat. When damage reduces you to 0 hit points, you can make a Charisma saving throw (DC 5 + the damage taken). On a success, you instead drop to 1 hit point. You can't use this feature if you are reduced to 0 hit points by radiant damage or by a critical hit.

After the saving throw succeeds, you can't use this feature again until you finish a long rest.

Channel Divinite

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Conquering Presence: You can use your Channel Divinity to exude a terrifying presence. As an action, you force each creature of your choice that you can see within 30 feet of you to make a Wisdom saving throw. On a failed save, a creature becomes frightened of you for 1 minute. The frightened creature can repeat this saving throw at the end of each of its turns, ending the effect on itself on a success.

Guided Strike: You can use your Channel Divinity to strike with supernatural accuracy. When you make an attack roll, you can use your Channel Divinity to gain a +10 bonus to the roll. You make this choice after you see the roll, but before the DM says whether the attack hits or misses.
