Starting at 3rd level, you can use your action to unleash the divine energy within yourself, causing a searing light to radiate from you, pour out of your eyes and mouth, and threaten to char you.
Your transformation lasts for 1 minute or until you end it as a bonus action. During it, you shed bright light in a 10-foot radius and dim light for an additional 10 feet, and at the end of each of your turns, you and each creature within 10 feet of you take radiant damage equal to half your level (rounded up). In addition, once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra radiant damage equals your level.
Once you use this trait, you can't use it again until you finish a long rest.
You have a pool of d6s that you spend to fuel this healing. The number of dice in the pool equals 1 + your warlock level.
As a bonus action, you can heal one creature you can see within 60 feet of you, spending dice from the pool. The maximum number of dice you can spend at once equals your Charisma modifier (minimum of one die). Roll the dice you spend, add them together, and restore a number of hit points equal to the total.
Your pool regains all expended dice when you finish a long rest.
As an action, you can touch a creature and cause it to regain a number of hit points equal to your level. Once you use this trait, you can't use it again until you finish a long rest.
