Citadel of Command

 Radiant Sanctuary: The area within a 60-foot radius of the Celestial Citadel transforms into a zone of celestial influence. The ground becomes pristine white marble, and the celestial columns emit a soft, radiant glow. This area is considered difficult terrain for hostile creatures.

 Awe-Inspiring Presence: As the celestial majesty of the Citadel takes hold, creatures within the radius, other than yourself and two designated allies, must make a Wisdom saving throw against your spell save DC. On a failed save, they are affected as if by the Command spell, following the command you issue for the duration of the spell. The DC is equal to 8 + your Wisdom modifier + your proficiency bonus.

Divine Protection: You and your two designated allies within the Citadel gain advantage on all saving throws while within the area.

Heavenly Judgment: Once per turn, as a bonus action, you can designate one creature within the Celestial Citadel. The target must make a Wisdom saving throw against your spell save DC. On a failed save, they take radiant damage equal to your cleric level and are restrained for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the restraint on a success.
