Cosmic Coronet (Patreon)

Wondrous item, artifact (requires attunement)

The thrall of cosmic power, of infinite potential; who could resist? A golden crown roiling with interstellar energy. While wearing this crown, you can use it as an arcane focus. While attuned to this item you can speak, read, and write Celestial. This item has 4 charges and regains 1d4 charges daily at dawn. Through time, accomplishment, and growth, this item can grow into its Awakened state, then into its Exalted state (according to your GM).

Dormant

The crown grants the following benefits in its dormant state:

While attuned to this item you gain a +1 bonus to spell attack rolls.

Protostar. When you roll for damage as a result of a spell that targets a single creature you can spend up to 3 charges to increase the amount of damage dice you roll by the number of charges spent.

Awakened

When the crown reaches an awakened state, it gains the following properties:

This item’s bonus to spell attack rolls increases to +2.

This item now can hold up to 6 charges and regains 1d6 + 1 charges daily at dawn.

Black Hole. When you or a creature within 40 feet of you is targeted by a spell of 6th level or lower that targets only a single creature, you can use your reaction to absorb the magic of the spell, canceling its effect. This item then gains a number of charges equal to the level of the absorbed spell. Once you use this property it can't be used again until you finish a long rest.

Exalted

When the crown reaches an exalted state, it gains the following properties:

This item’s bonus to spell attack rolls increases to +3.

This item now can hold up to 8 charges and regains 1d8 + 2 charges daily at dawn.

Constellation. You can spend 7 charges to cast the Crown of Stars spell. Once you use this property, it cannot be used again for 1d6 +1 number of days. When you make a spell attack against a creature with a mote created by the Crown of Stars spell while attuned to this item you can use the Protostar property to increase the number of damage dice you roll for that spell attack.

Shooting Star. You can cast the Wish spell without expending a spell slot. When you cast the spell through this item, your attunement to it is broken and this item vanishes, back to the realm from whence it came.

Behold, what blessings hath descended from what slumbers beyond the stars. Sights unseen, worlds unknown, knowledge unfathomable. Gifted to us from the alpha and omega that gazes down upon us as a lion does an ant. What machinations must be in motion for them to intervene with our paltry affairs, we cannot possibly hope to know; yet to turn them aside would be foolishness of the greatest magnitude. Do not deny our creator, and our destroyer. Time will come for us all.
