Where Is The Best Place To Farm For Dead Sword

I have seen alot more dead swords lately in the trade forums. Curious to where everyone is finding them I have opened about 250 chests in the last week between Remains of sahlahja and The realm of torment. With zero luck

Copied from GuildWiki:
Dropped by Undead and Mandragor in Istan Confirmed to drop in the Desolation and can also be found in Ancient Elonian chests. Dropped in Realm of Torment

I got one from a chest in the Poisoned Outcroppings. High req but it's still by far the coolest thing I have ever found. My mesmer looks forward to IW'ing with it.

Desolation is your best bet. I suggest Crystal Overlook, easy to farm for chests.

Yah leave from forgotten lair or go to the crystal outlook... I've opened maybe 1k ancient chests and never got a dead sword, but I was lucky enough to get an elemental sword
