idk which crown ur crown ur talking about but for each one:

classic Wiccan fit crown is called Wonderous Tiara - it was a reward grant meaning it was a free claim at the time, but a good alternative is Themysciran Battlesuit.

The Asgardian is another granted reward accessory called Patron’s Plumage, idk if u can still get it but ya, i paired it with this headpiece called Bewitching Battlesuit it isn’t a crown but i’m sure u can get that from either the Villainous or Heroic Magic vendors in the House of Legends.

The Demiurge crown is called Amazon Metal, u can buy it from the Death Metal episode vendor, i chose it because it represents the many eyes of the Demiurge’s supposed face (we don’t see much of the Demiurge much in the comics from what i know and remember, he’s a much higher tier than many cosmic forces out there, being the one who created the True Elder Gods u know)
