Your patron is a champion of light, an angel, coatl, kirin, or other powerful outsider who has invested in you a fragment of their divine radiance. Such beings rarely entrust their gifts with fallible mortals, so your pact is particularly noteworthy. Such patrons are known as heralds of radiance, or more often simply heralds, and often presage a world-threatening calamity.

Such patrons occasionally come to the aid of those who have already bartered away their souls frivolously, offering them a way out if only they will serve a greater good. Those who take them up on their offer often find a heavy burden comes in exchange for their “freedom”, as their new masters have high expectations of those in their debt. Redemption does not come cheaply or easily.

Expanded Spell List

The Herald lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Radiant Sense

Starting at 1st level, your patron bestows on you the ability to sense outsiders and unnatural beings. As an action, you can extend your senses to detect fiends, undead, and aberrations. Until the end of your next turn, you know the location of any such creature within 60 feet of you that is not behind total cover. You know the type (fiend, undead, or aberration) of any being you sense, but not its specific identity. Within the same radius, you also detect any place or object that has been consecrated or desecrated, as with the hallow spell. You can use this feature a number of times equal to 1 + your Charisma modifier. When you finish a long rest, you regain all expended uses.

Radiant Form

Starting at 6th level, your link to the divine energies of your patron begins to affect your physical form. Your appearance takes on a youthful and beautiful aspect. Whenever you would apply your proficiency bonus to a Charisma check, you may double that bonus.

Divine Resistance

Beginning at 10th level, your patrons radiant nature protects you from spells and other harmful effects. You gain a bonus to saving throws equal to your Charisma modifier (with a bonus of +1).

Searing Burst

Starting at 14th level, you can unleash a wave of radiant energy that harms and blinds nearby enemies. As an action, you may select any number of creatures within 10 feet of you. Each must succeed on a Charisma saving throw against your warlock save DC. On a failed save, it takes 4d6 radiant damage plus 4d8 fire damage and is blinded until the end of its next turn, or half as much damage on a successful save. Once you use this feature, you can't use it again until you finish a long rest.
