Circlet of Iron Will is a magic circlet given to Neia Baraja by Ainz Ooal Gown.
To protect Neia Baraja from any potential dangers, Ainz equipped her with this item prior to the Demi-Human Alliance's attack on Loyts.
The circlet resembles a golden ornamental headband, with an intricate crest in the front.
The circlet defended the mind against charm, fear and other such mental attacks. Still, while the crown rendered one immune to magical attacks, it could only strengthen the wearer's resistance against attacks derived from special abilities. It does not prevent the user from feeling fear that comes from within.
- Another thing to note was that the circlet would also negate positive magical effects.
