Hecate

Magic is an energy that suffuses the multiverse and that fuels both destruction and creation. Gods of the Arcana domain know the secrets and potential of magic intimately. For some of these gods, magical knowledge is a great responsibility that comes with a special understanding of the nature of reality. Other gods of Arcana see magic as pure power, to be used as its wielder sees fit.

The gods of this domain are often associated with knowledge, as learning and arcane power tend to go hand-in-hand. In the Realms, deities of this domain include Azuth and Mystra, as well as Corellon Larethian of the elven pantheon. In other worlds, this domain includes Hecate, Math Mathonwy, and Isis; the triple moon gods of Solinari, Lunitari, and Nuitari of Krynn; and Boccob, Vecna, and Wee Jas of Greyhawk.

Arcana Domain Spells

1st detect magic, magic missile

3rd magic weapon, Nystul’s magic aura

5th dispel magic, magic circle

7th arcane eye, Leomund’s secret chest

9th planar binding, teleportation circle

Arcane Initiate

When you choose this domain at 1st level, you gain proficiency in the Arcana skill, and you gain two cantrips of your choice from the wizard spell list. For you, these cantrips count as cleric cantrips.

Channel Divinity: Arcane Abjuration

Starting at 2nd level, you can use your Channel Divinity to abjure otherworldly creatures.

As an action, you present your holy symbol, and one celestial, elemental, fey, or fiend of your choice that is within 30 feet of you must make a Wisdom saving throw, provided that the creature can see or hear you. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.

A turned creature must spend its turns trying to move as far away from you as it can, and it can’t willingly end its move in a space within 30 feet of you. It also can’t take reactions. For its action, it can only use the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action.

After you reach 5th level, when a creature fails its saving throw against your Arcane Abjuration feature, the creature is banished for 1 minute (as in the banishment spell, no concentration required) if it isn’t on its plane of origin and its challenge rating is at or below a certain threshold, as shown on the Arcane Banishment table.

Arcane Banishment

Cleric Level Banishes Creatures of CR…

5th 1/2 or lower

8th 1 or lower

11th 2 or lower

14th 3 or lower

17th 4 or lower

Spell Breaker

Starting at 6th level, when you restore hit points to an ally with a spell of 1st level or higher, you can also end one spell of your choice on that creature. The level of the spell you end must be equal to or lower than the level of the spell slot you use to cast the healing spell.

Potent Spellcasting

Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.

Arcane Mastery

At 17th level, you choose four spells from the wizard spell list, one from each of the following levels: 6th, 7th, 8th, and 9th. You add them to your list of domain spells. Like your other domain spells, they are always prepared and count as cleric spells for you.

Clerics of the Moon Domain draw on their divine connection to the moons to wield light and shadow, invoke good fortune and ill favor, and reveal or conceal as they see fit. Most Moon clerics worship the Moonweaver herself, but her followers are as varied as the stars in the sky. Some seek to protect the vulnerable and do good in the world, while others meddle with impunity and distort the truth for selfish gain. Other Moon clerics worship not the gods but the moons themselves, especially those with an innate connection to the lunar cycles through lycanthropy.

Domain Spells

You gain domain spells at the cleric levels listed in the Moon Domain Spells table.

Moon Domain Spells

Cleric Level Spells

1st faerie fire, silent image

3rd invisibility, moonbeam

5th hypnotic pattern, major image

7th greater invisibility, hallucinatory terrain

9th dream, passwall

Clarity of Catha

When you choose this domain at 1st level, you learn to shine light upon the mind’s most dire moments, shielding those you protect. When a creature within 30 feet of you that you can see makes a Wisdom saving throw, you can use your reaction to grant that creature advantage on the save.

You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses when you finish a long rest.

Channel Divinity: Blessing of the Full Moon

Starting at 2nd level, you can use your Channel Divinity to infuse your allies with bestial power. As an action, you instill a willing creature of your choice within 30 feet of you that you can see with one of the following blessings of your choice:

Blessing of the Watchful Moon. For 1 hour, the blessed creature’s speed increases by 10 feet, and it has advantage on Wisdom (Perception or Survival) checks involving smell or made to track a creature.

Blessing of the Blood-Drenched Moon. For 10 minutes, the blessed creature has advantage on attack rolls against a target if at least one of the blessed creature’s allies is within 5 feet of the target and the ally isn’t incapacitated.

Channel Divinity: Mind of Two Moons

Starting at 6th level, you can use your Channel Divinity to invoke the twofold arcana of Exandria’s moons. By expending one use of Channel Divinity, you can cast a second concentration spell while already concentrating on a first spell, as long as both spells are on your list of Moon Domain spells. If you need to make a Constitution saving throw to maintain your concentration on both spells, you make the save with disadvantage. On a failure, you lose concentration on both spells.

Empowered Cantrips

Starting at 8th level, your cleric cantrips deal extra damage equal to your Wisdom modifier (minimum of 1).

Eclipse of Ill Omen

At 17th level, you can call upon the vermillion moon Ruidus to flare in the sky above you, eclipsing all other light. Its power surrounds you even where the sky can’t be seen, and even on other planes. As a bonus action, you can manifest an area of reddish, dim light in a 60-foot radius around you. In addition to the normal effects of dim light, creatures in the area make saving throws with disadvantage. When you create this eclipse, you can choose any number of creatures that are unaffected by it.

This eclipse lasts while you concentrate (as if concentrating on a spell) for up to 1 minute. Concentrating on this feature counts as concentrating on a Moon Domain spell for the purpose of your Mind of Two Moons feature. 

Additionally, once per turn when you deal radiant damage to any creatures in this area of dim light, you can curse one of those creatures until the eclipse ends (no action required). A creature cursed in this way has its speed halved and can’t regain hit points.  

Once you use this feature, you can’t use it again until you finish a long rest.

Gods of nature are as varied as the natural world itself, from inscrutable gods of the deep forests (such as Silvanus, Obad-Hai, Chislev, Balinor, and Pan) to friendly deities associated with particular springs and groves (such as Eldath). Druids revere nature as a whole and might serve one of these deities, practicing mysterious rites and reciting all-but-forgotten prayers in their own secret tongue. But many of these gods have clerics as well, champions who take a more active role in advancing the interests of a particular nature god. These clerics might hunt the evil monstrosities that despoil the woodlands, bless the harvest of the faithful, or wither the crops of those who anger their gods.

Nature Domain Spells

Cleric Level Spells

1st animal friendship, speak with animals

3rd barkskin, spike growth

5th plant growth, wind wall

7th dominate beast, grasping vine

9th insect plague, tree stride

Acolyte of Nature

At 1st level, you learn one druid cantrip of your choice. This cantrip counts as a cleric cantrip for you, but it doesn’t count against the number of cleric cantrips you know. You also gain proficiency in one of the following skills of your choice: Animal Handling, Nature, or Survival.

Bonus Proficiency

Also at 1st level, you gain proficiency with heavy armor.

Channel Divinity: Charm Animals and Plants

Starting at 2nd level, you can use your Channel Divinity to charm animals and plants.

As an action, you present your holy symbol and invoke the name of your deity. Each beast or plant creature that can see you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is charmed by you for 1 minute or until it takes damage. While it is charmed by you, it is friendly to you and other creatures you designate.

Dampen Elements

Starting at 6th level, when you or a creature within 30 feet of you takes acid, cold, fire, lightning, or thunder damage, you can use your reaction to grant resistance to the creature against that instance of the damage.

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 cold, fire, or lightning damage (your choice) to the target. When you reach 14th level, the extra damage increases to 2d8.

Master of Nature

At 17th level, you gain the ability to command animals and plant creatures. While creatures are charmed by your Charm Animals and Plants feature, you can take a bonus action on your turn to verbally command what each of those creatures will do on its next turn.
