Chest Farming

Well, my search function is not working, so I hope I'm not asking something that has already been done. If so, please post link and close thread.

I am curious as to what most people do for chest farming, and if they would like to post it here. I'll try to suggest a format and give an example:

Campaign / Location (NM/HM):
Key type:
Difficulty: (very easy / easy / moderate / difficult / very difficult)
Average # of chests per run:
Average time:
Cost benefit: (very poor / poor / break even / good / excellent)
Additional benefit:

Here's an example:

Campaign / Location: Nightfall, Mirror of Lyss NM, from Dzagonur or Kodash following elemental LB farming path past buried treasure
Key type: Vabbi (600g)
Difficulty: ve - e
# chests: 2-3
Time: ~10-15 minutes
Cost benefit: poor (merching returns about 2/3 of the gold you spend on keys)
Additional benefit: easy LB points

This is what I used to get my first treasure hunter rank, but the cost benefit is killer. I can do more difficult, but I'd like to hear what others do first.

Pre-ascalon chest running ftw!

I suggest just to look a little bit instead of creating a useless thread. There is an "Official Chest Running" thread. Search function isnt even needed.

Seek and you shall find...look at the top of the page The Chestrunner's Thread
