The Bow of the Banshee is located inside a Mimic chest that's found in a cave in the Dead Man's Pass area.
Description[]
| “ | A wooden face carved mid-scream stares out from the shaft of this hardwood bow. It's whispered that the half-orc archer Zavruk had an elven soul bound into the bow, but the bow's lack of a necromantic aura casts doubt on the story. What's certain is that the bowstring makes a horrible screeching noise whenever fired, instilling fear in the wielder's enemies. | ” |
