Aetherial Crown

 is a unique piece of in the The Elder Scrolls V: Dawnguard.

Properties
This lightweight circlet allows the Dragonborn to retain the last Guardian Stone power they selected, and allows them to select another.

Equipping the crown allows two Standing Stones powers to be granted simultaneously. If the crown is unequipped, the older of the two stones' effects is removed. Re-equipping it will restore the older effect.

Acquisition
It can only be crafted in the Aetherium Forge during the quest Lost to the Ages. It requires the following components:

Can be upgraded at a workbench with a Dwarven Metal Ingot, but this won't increase its armor rating.
 * 1 x Aetherium Crest
 * 2 x Dwarven Metal Ingot
 * 2 x Flawless Sapphire
 * 2 x Gold Ingot

Usefulness

 * Attaching the crown to a particular stone can allow it to be used in situational circumstances. For example, attaching it to the The Steed Stone allows it to become a useful item that can vastly increase carry weight when needed.
 * For a character interested in leveling up as quickly as they can, one can have both The Lover Stone and any of the three Guardian Stones.
 * Daily powers (such as the Ritual Stone) can be used multiple times per day by placing the specific stone on the Aetherial Crown and re-equiping after it is used, essentially reseting the power.
 * The 100% weakness to magic from the Apprentice Stone doubles the effects of spell absorbtion, thus increasing the amount The Atronach Stone absorbs.
 * Ordinarily Rested (+5% XP), Well Rested (+10% XP) and Lover's Comfort (+15% XP) are not given while having The Lover Stone as your active stone. The way around this is to store The Lover Stone in the Aetherial Crown and unequip it before resting. Using this method can yield as high an +XP% as 50% (if your other stone is one of The Guardian Stones during for 8 hours after resting. This is great if the quest you're about to go on is within 8 hours travel from home. If not, find a nearby inn, buy a room and settle for 45% +XP for 8 hours minus the journey to the nearby quest. Of course, being a Werewolf nullifies this entirely.

Trivia

 * With the Crown in the inventory or equipped, the Dragonborn may encounter Taron Dreth where he will ask information about the Crown. He will attack the player with his three mercenaries, no matter which option is chosen in the dialogue.
 * The crown can be worn with the Archmage's Robes because it counts as a circlet.
 * This crown is best, u shud get it! It makes me feel so good to wear it!

Bugs

 * The Crown can be worn along with a Falmer Helmet.
 * Even when all components are held, the Aetherial Crown may still not be able to be crafted.
 * The Crown may not retain the standing stone effect you had active before you equipped it. You have to visit both standing stones to gain an extra effect after equipping the Crown.
