Deity's Potency

Being chosen by a deity, you are able to increase your spell DC's for a limited time. You channel your deity's potency into your spells by spending one of your Channel Divinity class features as a bonus action for a number of rounds equal to your Constitution modifier. During this time, your spell DC increase by adding your Charisma modifier to your total DC value. At the end of your turn on the final round of Deity's Potency, you gain one level of exhaustion and must make a Constitution saving throw or gain the incapacitated condition for a number of rounds equal to your level. The DC is your increased spell DC you had during the time you had Deity's Potency activated.
