Obscenely low drop rate[]
If you value your life at all, don't waste a second of it trying to farm this. Even as an item level BLM, sweeping the tunnels left and right with AoE nukes with Myriad Mystery Boxes and treasure box boost Prowess after a version update that increased the drop rates for chests, I farmed chests in Outer Horutoto for 8 hours with no drop.--Blue Donkey Kong (talk) 00:57, November 18, 2013 (UTC)
Amaryllis Tower (northern West Sarutabaruta), do page 7 until you get Casket Discovery to 5, then go back to the goblin room and start killing stuff. Got mine in a few hours this way. (It took me 3 days in Den of Rancor to get my Goldsmithing torque!) --Elwynn (talk) 04:52, May 23, 2018 (UTC)
