It's been going around other forums and communities that there may be a manner in which to use one key to open an unlimited number of Black Lion Chests.
You may have also seen that the trade price of Black Lion Chests has gone up from a running average of ~3c to something insane on your server and that people are buying up to half a million of them at a time. (http://www.guildwarstrade.com/item/20316
The jump in price is due to the upcoming Halloween events.https://www.guildwars2.com/en/events/halloween-2012/
"The Black Lion Chest is getting a spooky upgrade for Halloween. Between October 23 and November 5 each Black Lion Chest you open has a chance to give you one of six exclusive Halloween-themed weapon skins!"
With regard to the supposed exploit, what's actually happening is that Black Lion Chests have a chance to drop an additional key depending on their rarity.
The appearance in a video may be that one key is being used multiple times to open the same stack of chests, but what's really happening is that the chests are dropping a new key each time.https://forum-en.guildwars2.com/forum/s ... ug-Exploit
Please move this to the nerfed section unless someone can figure out how to reproduce a true manner in which to unlock an unlimited number of chests with a single key.
I just wanted this posted on the Tault boards for search purposes.
