The Pearl seems to be the same size as the Onyx, being only slightly larger than a marble. It seems unremarkable. In fact, it doesn't show any magical property at all. It does however, seem warm to the touch, almost as if repelling the cold.

The Onyx itself is small, about the size of a marble. It's cold to the touch, almost as if repelling heat. In addition the black gemstone seems to absorb light around it, and pulses with magical energy.

WARNING: The Eyes are meant to be a late game item, and are not suitable for characters under level 15, please consider spend your early-mid game time collecting the stars of the Crown of Selûne instead. Addionally, please keep the eyes away from the crown until at least level 18 for best results. Blindsight/Truesight at anything below level 18ish is bonkers.

The location of both of the eyes is unknown, and researchers can only speculate what powers they might grant if both are ever returned to the crown.

When the Crown of Selûne was split into its seven parts and scattered across the material plane, one final measure was put into place to assure that even if the crown was put back together, only a small portion of its power would be accessable. Its true power was sealed inside two crystals, aptly named "Eyes of Selûne"

The Crown Restored - Part 1

Congrats!

Congrats, you are now level 20! (Or at the very least level 18, any lower and I would be worried about sending that Tarrasque after you.) No but seriouly, do not use this until a bare minium of level 18, you have been warned.

Step 1: Find the Phrases

The Crown in question is another brew of mine meant to tie a player over as they are leveling, as well as provide a neat magic item that will stay with them until they either die or reach this level.

To actually place the gems into the crown, you must have completed it first. Then procceed to the nearest temple of Selûne, place both the moonstone crown and each one of the gems you wish to insert onto an alter.

Under a new moon...

Resite the phrase for inserting the Onyx Stone:

By the dead moon I beseech you, grant me this boon. By the dark moon I beseech you, grant my allies sight on this dark night. By the empty moon I beseech you, grant me the power to resist temptations divine. By the new moon I beseech you, grant me the cover of darkness.

Under a full moon...

Resite the phrase for inserting the Pearl Stone:

By the lively moon I beseech you, grant me this boon. By the bright moon I beseech you, grant my allies eyes unwavering. By the orb of night I beseech you, grant me the power to resist this dark powers of this cold night. By the full moon I beseech you, grant me your moonlight.

For DM's The act of actually obtaining these phrases could be a quest in of itself, so use it to delay until a time at which you would want the crown abilites to be given to a player. A few quest ideas A good aligned werewolf pack (Selûne often helps good aligned WW's) wants help eliminating a red dragon, quest reward is the Onyx stone phrase.

A kraken is destroying ships near a port, a captain wants the aventurers' help dealing with the problem. The quest reward might be pearl stone phrase.

Step 2:Divine Intervention

It's up to each indiviudal DM how they want to do this part, but imagine moonlight seeping down through the moon roof/windows (whaever really), acting like a liquid and melding the gems to the moonstone crown. Or in the case of a new moon, the alter itself seems to glow with moonlight, blinding everyone and revealing a crafted crown with an Onyx inside it.

Step 3: The Finished Product

After this point, only the crown requires attunement, and the effects of the merge are now irreversable, the only thing that can break it is Selûne herself.

The stars spawned by the crown are now either black, or white, and glow a soft blue moonlight. If you manage to get both gems, the stars now go through the full phases of the moon, shifting from dark to light and back again. This does not reduce the light radius.

With the completed crown you now have access to the level 20 capstone skill for divine intervention, but can only contact Selûne.
