How to get Legendary Hunter Class Mod
Legendary Hunter class mods are a rare drop from the boss Vermivorous the Invincible.
They can also be found in gun chests, or can be purchased from Dr. Zed's vendor as Item of the Day.
They can also be dropped by Loot Wee Gun Loaders, which are most commonly found near Hyperion locations.
The chest in the Rotgut Distillery DLC that requires the player to complete the DLC and kill all the threshers can also spawn it.
Upon release of the Loot the World iPhone application, released on December 12, 2013, there was a barcode found that granted the Legendary Hunter Class Mod.
