Medallion of Mental Protection

Medallion of Mental Protection is a magic item that protects the wearer against mental attacks.

Description
Jircniv Rune Farlord el Nix wears one under his garments. Though it's said that the medal is effective precisely because people did not know it was there in the first place.

Abilities
The medal possesses magic that gives one mental protection, however, its power seems to only provide protection so long as the wearer keeps his/her mind focused. With this, the mental barrier is enough to ward off Demiurge's mind control.

Trivia

 * The Blood Emperor keeps the knowledge of this item a secret.
