Circlets are crowns that can be found in the apparel section of the inventory.

AcquisitionEdit

Circlets can be found as random loot in dungeons or bought from merchants. Characters that can be seen wearing circlets include all the Jarls of Skyrim, except Ulfric Stormcloak and Idgrod Ravencrone. They cannot be crafted at blacksmith forges.

AttributesEdit

Certain enchantments can be placed on circlets such as the Mage's Circlet and its 20-70 magicka bonus.
Circlets count as clothing and thus the benefits of the Alteration perk "Mage Armor" are received with circlets equipped.
Circlets can be worn with the Penitus Oculatus helmet, a Dragon Priest Mask, or a Falmer Helmet (but not a Falmer Hardened Helm) while the benefits from both items will still be retained. That is why circlets are often used with Falmer Helmets to increase a certain skill.
Circlets are one of the few types of headgear that may be worn with the Archmage's Robes, which comes with a hood and prevents the wearing of most head pieces.
