Lunarian Knight

A Lunarian Knight is a wielder of moonlight and celestial energies, blessed with the powers of the moon itself. These warriors channel the waxing and waning phases of the moon to augment their combat abilities, as well as tap into the profound cosmic mysteries hidden within the night. A Lunar Knight is not merely a fighter but a vanguard of nocturnal power, blending martial prowess with strange eldritch magic related to the moon’s cycles, tides, and reflected light. As they grow in power, Lunar Knights become fierce warriors in the dark, defenders of cosmic balance, and ruthless guardians of night-born magic.

You have learned to cast spells.

Cantrips. You know two cantrips of your choice from the Cleric spell list. Whenever you gain a Fighter level, you can replace one of these cantrips with another cantrip of your choice from the Cleric spell list.

When you reach Fighter level 10, you learn another Cleric cantrip of your choice.

Spell Slots. The Lunarian Knight Spellcasting table shows how many spell slots you have to cast your level 1+ spells. You regain all expended slots when you finish a Long Rest.

Prepared Spells of Level 1+. You prepare the list of level 1+ spells that are available for you to cast with this feature. To start, choose three level 1 spells from the Cleric spell list.

The number of spells on your list increases as you gain Fighter levels, as shown in the Prepared Spells column of the Lunarian Knight Spellcasting table. Whenever that number increases, choose additional spells from the Lunarian spell list until the number of spells on your list matches the number on the table. The chosen spells must be of a level for which you have spell slots. For example, if you’re a level 7 Fighter, your list of prepared spells can include five Cleric spells of levels 1 and 2 in any combination.

Changing Your Prepared Spells. Whenever you gain a Fighter level, you can replace one spell on your list with another Cleric spell for which you have spell slots.

Spellcasting Ability. Wisdom is your spellcasting ability for your Cleric spells.

Spellcasting Focus. You can use an Arcane Focus as a Spellcasting Focus for your Cleric spells.

Lunar Shout

As a bonus action, you emit a concussive shout infused with lunar resonance. All enemies within a 30-foot radius must succeed on a Wisdom saving throw (DC 8 + your Wisdom modifier+ your proficiency bonus) or become Frightened until the end of their next turn. Creatures suffering from the Frightened condition due to this ability also have their movement halved for its duration. You can use this ability an amount of time equal to your proficiency bonus every long rest.

Lunar Blade

Once per short rest, the Lunarian Knight can summon a spectral sword that deals 2d8 radiant damage when they hit a target. If the target is undead or a lycanthrope, this damage increases to 3d8.

Eclipse Wrath

The Lunarian Knight can call forth the power of a darkened moon for a single strike, dealing an extra 3d6 necrotic damage. If the target fails a Constitution saving throw (DC = 8 + proficiency bonus + Wisdom modifier), they are also blinded until the end of their next turn.

Moonlit Surge

When you use Action Surge, you gain temporary lunar-infused damage bonuses. These bonuses give a +1d12 radiant damage to every attack within the next two rounds.

Crescent Retaliation

Once per day, after taking a critical hit, you can call upon the moon’s vengeance to inflict the same critical damage back on the attacker. Immediately after using this ability, you emit a burst of radiant light in a 10-ft radius around you. Hostile creatures in this radius must succeed on a Constitution saving throw (DC = 8 + your proficiency bonus + your Wisdom modifier) or be stunned for 1 round.
