Aura of Holy Flame

As a servant of the light your powers shine like the sun, emboldening and strengthening you and your allies. All evil that dares stand against your holy purpose is met with the purging fires of righteousness.

You and friendly creatures within a 30ft radius of you are resistant to fire and radiant damage. All hostile creatures within the radius are vulnerable to fire damage. Additionally, if the hostile creature is evil aligned, it is vulnerable to radiant damage as well. Any hostile creature within the radius with immunity or resistance to either fire or radiant damage loses those immunities and resistances for as long as it remains within the radius. Any hostile creatures who enters this area, begins there turn here, or ends their turn here takes 3d6 fire damage, if the creature is evil aligned, it takes an additional 2d10 radiant damage.

As an action, you may present your holy symbol and utter a prayer. Each hostile creatures within the radius that can see or hear hear you must make a Constitution saving throw against your spell save DC. On a failed save, the creature takes 3d6 Fire damage, on a successful save the creature only takes half. An evil aligned creature takes an additional 2d10 radiant damage. You may use this feature a number of times equal to your charisma modifier and regain all expended uses whenever you complete a long rest.
