Aiffe's Mandolin in Heroes 4

Grants the hero the ability to cast Song of Peace, Unholy Song, and Mass Fervor when worn. Targets attacked by a hero wearing the Harmonic Chanmail, the Necklace of Muses, and wielding Aiffe’s Mandolin are effected by Song of Peace, as if the spell was cast on them.

The legendary bard Aiffe once claimed this mandolin for her own. Even now it seems slightly warm to the touch, almost as if someone had been holding it recently. Seemingly possessed with a life of its own, any song can fly from it with ease—a soothing lullaby, a wailing dirge, or even a rousing hymn.
