Crown of Selûne

Lore

The Crown of Selûne was crafted for only the most devoted of Selûne's worshippers. It took the appearence of seven stars that circled around the wearers head, they glowed, emiting a soft blue moonlight.

It was a gift that could not be given lightly, it has been in the hands of a many chosen over the course of few millennia, but as wars grew rampent in the material plane, Selûne thought it best to remove the crown from the equation.

She split the crown into seven stars, and the sealed its magic in two glass eyes, so that even if someone managed to restore all seven stars, they would still not have access to the true power of the crown.

Collecting the Stars

A player who wishes to collect the stars must do so one at a time, and each star collected adds to the total power of the crown. The crown itself is in essence an activated Crown of Stars spell, but collected one mote at a time.

Additonally the stars emit moonlight similar to the Crown of Stars, but don't start emitting it until at least 2 stars have been collected. The stars damage is also scaled down for players who want to hunt them while leveling.

The Wearer of the crown can use Crown of Stars once per short rest without expending a spell slot (This costs an action) , but can only summon stars up to the number of motes they have collected.

Once all the stars have been collected, the wearer gains the ability to cast Crown of Stars three times per long rest without expending a spell slot.

Not sure about the damage scaling, but without bonus effects and the fact that it is chip damage I scaled if off the average damage that spells push out from 2nd to 7th. This entire damage scaling chart is subject to change. r/UnearthedArcana
