Ashen Elf Trickster Priest

Blessing of the Trickster. As an action the Priest can touch a willing creature other than themself to give it advantage on Dexterity (Stealth) checks for 1 hour or until the Priest uses this feature again.

Channel Divinity. The Priest can channel divine energy to fuel magical effects twice per short rest.

• Channel Divinity: Cloak of Shadows

  As an action, the priest can use Channel Divinity to become invisible until the end of their next turn or until they attack or cast a spell.

• Channel Divinity: Invoke Duplicity

  As an action, the priest can use Channel Divinity to create an illusion of themself that lasts for 1 minute, or until they lose your concentration (as if you were concentrating on a spell). The illusion appears within 30 ft. of them. As a bonus action, they can move the illusion up to 30 ft., but it must remain within 120 ft. of the priest. they can cast spells as the illusion, and when both they and their illusion are within 5 feet of a creature that can see the illusion, they have advantage on attack rolls against that creature.

• Channel Divinity: Turn Undead

  As an action, the priest presents their holy symbol and speaks a prayer censuring the undead. Each undead that can see or hear them within 30 feet of them must make a WIS saving throw (DC 15). 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 the priest as it can, and it can’t willingly move to a space within 30 feet of them. 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.

• Destroy Undead. CR 1/2 or Lower. When an undead fails its saving throw against the priest's Turn Undead feature, it is instantly destroyed if its CR is lower than the threshold for 1/2.
