Moon Blade

Transmutation cantrip

• Casting Time: 1 bonus action
• Range: Touch
• Components: V, S, M
• Duration: 1 minute

When cast, choose one rapier, short sword, or scimitar you are holding. It is surrounded by a radiant glow, forming a blade resembling the crescent moon. For the duration, you can use your spellcasting ability instead of Strength or Dexterity for the attack and damage rolls of melee attacks using that weapon, and the weapon's damage die becomes a d8. The weapon also becomes magical, if it isn't already. The spell ends if you cast it again or if you let go of the weapon.

If you do not have a rapier, a short sword, or a scimitar, the moonlight shape and form a magical Moon Blade in your hand. You are proficient with the Moon Blade.

Star Bubble

Abjuration cantrip

• Casting Time: 1 action
• Range: Self
• Components: V, S
• Duration: 1 minute

When cast, you are enveloped in a faint glow as the starry bubble forms, providing a visually captivating display.

While the Star Bubble is active, the caster gains a +1 bonus to their Armor Class, representing the celestial energy's ability to deflect incoming attacks. Additionally, the starry barrier emits a soft light in a 5-foot radius, providing dim light in the area.

The bonus to Armor Class from this spell does not apply if the caster is wearing an armor or holding a shield.

The protective bonus to Armor Class increases by +1 when this cantrip reaches 11th level (+2).

Conjure Planetarium

3rd-level conjuration

• Casting Time: 1 action
• Range: 120 feet
• Components: V, S, M
• Duration: 1 minute

Choose a spot within range. You summon a 20-foot-radius see-through sphere centered on that spot. The surface of the sphere is patterned like a planetarium, depicting constellations and nebulas, planets and star systems. The subtle hum of distant cosmic energy is the only thing heard within the sphere.

Within the sphere, gravity is greatly lessened. Creatures and loose objects float upward at a speed of 10 feet per round until they reach the top of the dome, at which point they stop and float in place. Fixed objects or creatures not fully enclosed by the sphere are unaffected. Within the dome, creatures can only move if they can push off against a stable surface (such as a wall or ceiling, or a creature too large to be enclosed) or are pushed by other means. If they do, all movement costs extra movement as if it were difficult terrain. A creature can make a Dexterity Saving Throw to grab onto a fixed object within reach to avoid floating upward. At the end of the spell's duration, gravity returns to normal, and all creatures and objects fall back down.

The planetarium serves as more than a visual spectacle. Inside it, these effects activate:

• Ranged attack rolls that enter the sphere are rolled with disadvantage.
• Aside from the cosmic hum, no other sound can be heard inside the sphere, or pass through it.
• All creatures entirely enclosed by the sphere are immune to thunder damage, and are deafened for as long as they remain within it.
• Spells with verbal components cannot be cast within the sphere.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radius of the spell's area of effect increases by 5 feet per spell level above 3rd.

Sternritter

3rd-level transmutation

• Casting Time: 1 action
• Range: Self
• Components: V, S, M (a shard of a fallen star)
• Duration: Concentration, up to 1 minute

This spell transforms the caster into a radiant embodiment akin to a star knight. When cast, the shard of a fallen star is consumed in a burst of stellar energy, surrounding the caster in an aura of brilliance.

You gain the following benefits until the spell ends:

• You have advantage on Wisdom saving throws
• You regain the maximum number of hit points from any healing.
• You have a +2 bonus to AC.
• All your weapon attacks are magical, and when you make a weapon attack, you can use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls.
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that lets you attack more than once when you take the Attack action on your turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the number of attack you can make increases by 1.

When the spell ends, either because you lost concentration or you decided to end it early, the incarnation of the moon launches forth and explodes in a brilliant flash of light. Choose a spot that you can see within 120 feet of you. All creatures within 20 feet of it must make a Dexterity Saving Throw or take damage equal to the spell's accumulated damage. They also lose their resistances until the end of your next turn. On a successful save, they take half damage and do not lose their resistances.

The spell's base damage is 8d6. If at the end of your turn the bead has not yet detonated, the damage increases by 1d6.

Anti-Magic. While holding this spell, you have resistance against all damage dealt to you by spells. Spell attacks against you are made with disadvantage, and you have advantage on saving throws to resist the effects to spells.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the spell's base damage increases by 1d6 and the sphere's radius increases by 5 feet for each slot level above 5th.

Stellar Nova

9th-level evocation

• Casting Time: 1 action
• Range: 10 miles
• Components: V, S, M (a heart of a dying star or a valuable gem worth at least 25,000 gp, which the spell consumes)
• Duration: Instantaneous

Stellar Nova represents the pinnacle of celestial destruction, harnessing the power of stars to obliterate enemies within 1-mile radius. This is the magic that gods use to destroy a civilization of the past.

The caster summons the raw power of the stars, creating a cataclysmic explosion known as Stellar Nova. A brilliant burst of radiant energy erupts in a 500-foot radius sphere centered at a point within range. All creatures caught in the area must make a Constitution saving throw. On a failed save, a creature takes 5d8 + 40 radiant damage and is blinded for 1 minute. On a successful save, the damage is halved, and the creature isn't blinded.

The radiant energy unleashed by Stellar Nova is so intense that it pierces through magical defenses. This spell automatically disintegrates magical or nonmagical objects or creations of magical force. Creatures that dies from this spell and everything it is wearing and carrying are reduced to a pile of fine gray dust. Magical items of very rare rarity or above survive the blast.

Creatures within the area that have resistance to radiant damage still take full damage from this spell.

This spell can penetrate most barriers, but it can be blocked by 2 feet lead, 5 feet metal, or 15 feet stone.

The spell's radiant aftermath leaves a lingering effect, the area within the spell's radius is considered nonmagical difficult terrain. For the next minute, any creature starting its turn within the next minute takes 1d10 radiant. For the next day, 1d8 for every minute spent there. For the next month, finishing a short or long rest will deal 1d6 radiant. For the next year, a long rest will deal 1d4.
