GW2: Updated Dry Top drop list
by MANYLAUGHS on AUGUST 11, 2014
Not sure if the wiki has totally caught up, yet, but it’s still useful to have this information in one place. Here’s the latest T6 (with the occasional T5) drop list for Dry Top:

In addition to the sweet T6 mats that drop in Dry Top, every enemy appears to have a chance of dropping a Zephyrite Lockpick, as well as rare weapons and, on occasion, rare armor. The rare weapon drops are overwhelmingly more common.

[ul]
[li]Dust Mites: Crystalline Dust, Charged and Onyx Lodestones[/li]
[li]Dust Mite Twisters: Crystalline Dust, Charged and Onyx Lodestones[/li]
[li]Arid Devourers: Powerful Venom Sacs and Armored Scales[/li]
[li]Wind Riders: Powerful Venom Sacs[/li]
[li]Colocals: Vials of Powerful Blood and Vicious Claws[/li]
[li]Inquest: Elaborate Totems, Piles of Incandescent Dust and Piles of Crystalline Dust[/li]
[li]Vulture Raptors and Pink Moas: Vicious Claws[/li]
[li]Salamandar Drakes: Drop T5 mats – Large Claws and Large Scales. I haven’t seen any T6 mats drop from the Drakes, yet.[/li]
I beli
[/ul]eve the Mordrem Wolves drop Vicious Fangs, but I haven’t been able to confirm that, yet.

General farming observations: I’ve found the Moas and Wind Riders particularly easy to farm. The Dust Mites are easy to gather in groups, so you can farm lots at once. The Arid Devourers take a little longer to kill, but the drops are worth it.

The Haze Event is full of Dust Mites and Arid Devourers and it spawns twice during the dust storm, once at the beginning and once with 10 minutes left to go in the dust storm, if someone triggered the first event at the beginning of the dust storm.
