Divine Reckoning

Your connection to your fallen divinity has reached its peak. You can now unleash a devastating attack that draws upon the full might of your former godhood. As an action, you can expend a number of spell slots equal to your Wisdom modifier to unleash a Divine Reckoning. This attack deals 6d10 + your Wisdom modifier radiant damage to a single target within 120 feet. If the target is a creature, it must make a Constitution saving throw against your spell-saving DC. On a failed save, the target is also stunned for 1 round. You can use this feature once, and you regain the ability to use it after a long rest.
