Radiant Light

True Illumination

Your connection to the Plane of Radiance grants you control not just over light, but also an ability to channel the adjacent elements of fire and positive energy. When you learn or replace spells from your Spellcasting feature, you can choose to learn those spells from the cleric spellcasting list. The spells cannot be of the enchantment school, or necromancy school if they channel negative energy. Once you learn a cleric spell, it counts as a sorcerer spell for you.

Note: You can also choose from any spells with the Light subtype.

Additionally, when you learn a spell that deals fire or thunder damage, you can instead choose to learn a variation of that spell that deals radiant damage instead.

LIghtbringer

Additionally, you mark your foes for your lights' wrath. Whenever you deal fire or radiant damage to a creature, you may make them Illuminated for the next minute. While a creature is Illuminated, they shed bright light around them for 5-feet, and then dim light for another 5-feet. They cannot use any invisibility ability nor hide while illuminated.

If the target(s) are still illuminated when you hit them with your next spell. The illumination will be consumed and deal 1d6 radiant damage to them.
