Swamplight Lantern Drops in heroic Slave Pens
Got tired of farming heroic Slave Pens for the Swamplight Lantern, got even more tired of farming Arcatraz for a slightly different color of the same model, and I didn't feel like spending my Justice Points on Hermit's Lamp. I lucked out and found Dreamseeker Dandelion for sale at the Auction House, so I went with that for my offhand.
Alternate weapon: Redemption. Drops in what we used to call Live Strat.
