Blight of the Gods

The sky breaks apart and a great beam of holy light blasts down at the target, that is if you use celestial blood. If you use the horn of a demon, then a beam of pure hellfire blasts from you hand at your target. If you shoot a beam of holy light, you deal 5d6 times 1d12 radiant damage, dealing an extra 3d6 radiant damage to undead and fiends. If you shoot a blast of hellfire at your enemy, you deal 5d6 times 1d12 necrotic damage, dealing an extra 3d6 necrotic damage to celestials and angels.

To shoot a beam of holy light you must be a Circle of Dreams Druid, a Horizon Walker Rand, a Warlock of the Celestial, a Light Domain Cleric, a Oath of Heroism Paladin, a Divine Soul Sorcerer, or a Evocation Wizard. To shoot a beam of hellfire you must be a Circle of the Moon Druid, a Warlock of the Fiend, a Death Domain Warlock, and Oathbreaker Paladin, a Shadow Magic Sorcerer, a Gloom Stalker Ranger, or a Necromancy Wizard. Due to the many spells known by the College of Whispers and Warlocks of the Hexblade, they know how to cast both spells.
