Oath of Radiance Spells

Channel Divinity: Incandescent Flare

You can use your Channel Divinity to blind your enemies and light up the area around you. As an action, you force each creature of your choice that you can see within 30 feet of you to make a Constitution saving throw. On a failed save, a creature becomes blinded for 1 minute. The blinded creature can repeat this saving throw at the end of each of its turns, ending the effect on itself on a success.

Channel Divinity: Purging Light

You can use your Channel Divinity to attempt to purge the darkness from one creature you can see within 30 feet of you. As an action, you can force one creature to make a Constitution saving throw. On a failure a creature takes radiant damage equal to 2d8 + half your Paladin level (rounding up). On a success a creature takes half as much.

Radiant Body

Starting at 7th level, light permeates your body. You begin to radiate bright light in a 15-foot radius around you and dim light for an additional 15-feet. As a bonus action you can diminish the light to a faint glow casting no light or you can restore the light to its full radiance.

If a creature makes a melee attack roll against you while you are at full radiance you may use your reaction to briefly blind them imposing disadvantage on the roll. At 18th-level, the creature also takes radiant damage equal to your Charisma modifier.

Illuminant Mind

Starting at 15th level, light permeates your mind allowing you to see normally in darkness, both magical and nonmagical, to a distance of 120 feet. If any of your spells and effects that generate light overlap with an area of magical darkness created by a spell of 5th-level or lower the spell that created the darkness is dispelled.

You also gain proficiency in Intelligence saving throws and have advantage on Insight checks made to detect lies or similar deceptions.

Refulgent Soul

Starting at 20th level, light permeates your every aspect of your being. As an action, you can undergo a transformation becoming the avatar of light, the Lightwalker, gaining the following benefits for 1 minute:

• You gain resistance to radiant and necrotic damage.
• You emanate an aura of burning ethereal light in a 30-foot radius filling the space with dim light. Creatures of your choice that enter or start their turn within the aura must succeed on a Constitution saving throw against your spell save DC or take 7 (2d6) radiant damage and grants you advantage on attack rolls against it until the start of the targets next turn.

Once you use this feature, you can't use it again until you finish a long rest.
