Circlet of Iron Will

The Crown of Iron Will is a magic crown given to Neia Baraja by Ainz Ooal Gown.

Description
To protect Neia Baraja from potential dangers, Ainz equipped her with this item prior to the Demi-Human Alliance's attack on Loys.

Appearance
The crown resembles a golden ornamental headband, with an intricate crest in the front.

Abilities
The crown 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 its user from feeling fear that comes from within.

Trivia

 * Another thing to note was that the crown would also negate positive magical effects.
