You or someone from your lineage has been exposed to the concentrated magic of the moon (or moons) of your world, imbuing you with lunar magic. Perhaps your ancestor was involved in a druidic ritual involving an eclipse, or maybe a mystical fragment of a moon crashed near you. However you came to have your magic, your connection to the moon is obvious when you cast sorcerer spells-perhaps making your pupils glow with the color of a moon from your world, causing spectral manifestations of lunar phases to orbit you, or some other effect.
At 3rd level, whenever you finish a long rest, you can choose which lunar phase manifests its powers through your magic: Full Moon, New Moon, or Crescent Moon.
Additionally, you learn additional spells when you reach certain levels in this class, as shown below. Each of these spells count as a sorcerer spell for you, but don't count against the number of sorcerer spells you know. You can cast the 1st level spell associated with your moon phase without expending a spell slot once per short or long rest.
Starting at 3rd level, you can call down the radiant light of the moon on command. You learn the Sacred Flame cantrip, which doesn’t count against the number of cantrips you know. When you cast the spell, you can target one creature as normal or target two creatures that are within 5 feet of each other.
At 6th level, the current phase of your Lunar Embodiment can affect your Metamagic. Each phase is associated with certain schools of magic.
Full Moon. Abjuration and Divination spells.
New Moon. Enchantment and Necromancy spells.
Crescent Moon. Illusion and Transmutation spells.
Whenever you use Metamagic on a spell associated with your current Lunar Embodiment phase, you can reduce the Sorcery Point cost of the Metamagic by 1.
Starting at 6th level, you gain greater control over the phases of your lunar magic. As a bonus action, you can spend 1 sorcery point to change your current Lunar Embodiment phase for a different one.
Starting at 14th level, the power of a lunar phase saturates your being. While you are in a Lunar Embodiment phase, you also gain the following benefit associated with that phase:
Full Moon: You can use a bonus action to shed bright light in a 10-foot radius and dim light for an additional 10 feet or to douse the light. In addition, you and creatures of your choice have advantage on Intelligence (Investigation) and Wisdom (Perception) checks while within the bright light you shed. You also gain a flying speed of 20 feet when shedding this light.
New Moon: You have advantage on Dexterity (Stealth) checks. In addition, while you are entirely in darkness, attack rolls have disadvantage against you, and you have advantage on attack rolls.
Crescent Moon: You have resistance to necrotic and radiant damage. Whenever you deal damage with a spell or cantrip that deals radiant damage, you can add your Charisma modifier to the damage roll.
At 18th level, as a bonus action, you can tap into a special power of your current Lunar Embodiment phase. Alternatively, as part of the bonus action you take to change your lunar phase using the Waxing and Waning feature, you can immediately use the power of the lunar phase you are entering:
Full Moon: You radiate moonlight for a moment. Each creature of your choice within 30 feet of you must succeed on a Constitution saving throw against your spell save DC or be blinded until the end of its next turn. In addition, one creature of your choice in that area regains 5d8 hit points.
New Moon: You momentarily emanate gloom. Each creature of your choice within 30 feet of you must succeed on a Dexterity saving throw against your spell save DC or take 3d10 necrotic damage and have its speed reduced to 0 until the end of its next turn. In addition, you become invisible until the end of your next turn.
Crescent Moon: You can magically teleport to an unoccupied space you can see within 60 feet of yourself. You can bring along one willing creature you can see within 5 feet of yourself. That creature teleports to an unoccupied space of your choice that you can see within 5 feet of your destination space. In addition, you and that creature gain resistance to all damage until the start of your next turn.
Once you use one of these bonus action benefits, you can’t use that benefit again until you finish a long rest, unless you spend 5 sorcery points to use it again.
