At 1st level, you gain proficiency in Deception.
Improved Minor Illusion
Also at 1st level, you learn the minor illusion cantrip. When you cast this cantrip, you can create both a sound and an image with a single casting of the spell.
Channel Divinity: Shadow Conjuration
Starting at 2nd level, you can use your Channel Divinity to infuse your spells with the essence of the shadowfell. As a free action when you cast an Illusion, you cause any checks made to see through or disbelieve that illusion to suffer disadvantage.
Beginning at 6th level, when you cast an illusion spell that has a duration of 1 minute or longer, you can use your action to change the nature of that illusion (using the spell's normal parameters for the illusion), provided that you can see the illusion.
Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.
By 17th level, you have learned the secret of weaving shadow magic into your illusion to give htem semi-reality. When you cast an illusion of 1st level or higher, you can choose one inanimate, nonmagical object that is part of the illusion and make that object real. You can do this on your turn as a bonus action while the spell is ongoing. The object remains real for 1 minute. For example, you can create an illusion of a bridge over a chasm, and then make it real long enough for your allies to cross.
The object can't deal damage or otherwise directly harm anyone.
