EDIT: ADDING THE DUPE INSTRUCTIONS TO THE FIRST POST TO AVOID CONFUSION!!
I want to see replies from people that actually play this game and I want to see if anybody even cares about this... Post in this thread, it'd be cool if you put your server history and faction, etc... Drop some old names, whatever... I just want to see interest. If the responses come, I will fully explain, step by step, how to duplicate any BoE item. I will explain how to use this to practically dupe gold just by vendoring a certain item you can keep duping over and over. I want to avoid giving hints out but to be fair I will say a few more things.
1) Any player with access to a guild bank can dupe. If you don't have access to one, ask people in advice chat to help you start one. It takes 6 people in your party to go up to the guild hall entrance in Inevitable City or Altdorf depending on your faction. You now have your own bank to avoid people seeing your activities and getting suspicious. I would recommend using your own guild anyway unless your current guild allows access to the bank AND nobody is online but you.
2) Any player that meets the criteria to the first rule can successfully dupe any BoE item that they have 3 or 4 of to begin with. Obvious candidates are golden scarabs, potions, liniments, herbs (especially smart to dupe the main ingredient for liniments you use since they can stack up to 50 which crafts 100 liniments with the correct ingredients... way more practical since 5 stacks worth of liniments fit into one stack if you just keep the main ingredient... and even though the liniment seeds are near impossible to get now, the actual ingredient that comes from cultivating the seeds can be traded and can be found on the AH)... Even dyes, talismans, containers, and anything else you can think of. You'll be able to get anything duped from this point on so I recommend you go all out and use the best pots, highest talismans, etc....
3) If you only have 1 of the item you want to dupe, it can be done but it's not as easy. I'll explain this too but if I give any more details it will be too easy to figure out with the info I already provided. Also, even though it can be done, I would still use the easy way out and spend the gold to start with multiples already which speeds up the process. Hell, use a few stacks to begin with if you can, that way you don't have to duplicate a bunch of single items, stack them up, and then dupe stacks of 20 when you finally have enough... Spend your gold if that's all it takes! You're just gonna get more anyway when you dupe the shit out of it!
4) There are certain things you can't put into the guild bank. Mythic did this because they CAN'T fix the current dupe method so their idea of damage control was just to block certain items from the bank... Well, they lazily forgot to block the ingredient that makes the item to begin with. Examples: Speed of the Blowing Sands (30% runspeed potion) cannot go in the bank, but stacks of Sacred White Lotus (the ingredient used to make the potion) can! Odjira (runspeed proc talismans) can't be banked, but Golden Relic of Nagash, the main ingredient, can be stacked up to your hearts content!!
5) There are certain items you may already have that are no longer obtainable.... there are items you may have that are worth a fortune to the twink market! For example, if you used to play this game a few years ago and haven't touched your account since, you should know that any low level (below level 10) helmets, shoulders, cloaks, and most of the better weapons have been taken off the loot tables, but they dropped like crazy 3 years ago or longer when you probably tried this game out! If you're somebody who either wants a reason to resub and try the game out again, this could be a very nice surprise when you log on and find out your inventory has tons of this crap stockpiled away... The game now has an endless free trial that allows you to play in tier 1 up to level 10 and never have to subscribe. Your character will just stop gaining experience at rank 10. You can reach Renown Rank 20 which gives you a LOT of points to spend on speccing for extra stats or renown abilities. 20 points to spend at level 10 can be godlike if you know what to take. These accounts can't send mail or trade, but they can RECEIVE mail. People level up characters to rank 10 RR20 and then use a subscribed account to mail themselves potions, helmet/shoulder armor with the best usable talismans along with cloaks and anything else they need. This is what twinking consists of in this game. Check all your random low level characters' bags and banks to see what you might have lying around. Anything that was never equipped is still BoE, and by that I mean DUPE-ABLE. If the free trial twinking has you interested I don't mind making a guide for that either so reply and mention it in the thread if you want it.
I have my doubts that anyone will even read this post, let alone actually play the game and care to know the details... Just post in the thread if you're interested, take a minute to mention if you're currently subscribed, if you're a past player, what servers you started on and played on, anything like that I'm interested to hear! If you wanna shout out your old guild, go for it, I might remember them! You don't have to shout out your character's names or anything but it's not like Mythic would care anyway LOLOL.
Before I go I just want to clarify my reasoning behind this. I played this game from launch day for 2 solid years having a total blast, and after that I still never stayed away long. I play for a few months at a time on and off because the game is still the best PvP MMO on the market and it still has fun to offer. The reason I would publicly release a dupe for a game I like is simple. The game has been dying since it came out, there's no telling how long EA will keep the servers up and running since it's been in maintenance mode for over 3 years now, and it hasn't had a REAL economy since. Therefore, duping has no implications to the game besides letting people have fun without being called a scrub for skipping out on potions and good talismans. If you're still playing you know how hard it is to earn gold in the state the in-game economy is in. There is hardly a market for anything and I'm amazed people even attempt to sell things on the AH! I want to provide people a way to enjoy the game without having to struggle with gold and consumables. Also, returning players that might have level 40 characters from a few years ago will find out that renown rank has become a free handout compared with the way it was at launch, so your old rank 40, RR45 that you used to play with pride now looks like a toddler in a sea of RR80-100s. Since the best PvP gear has renown rank requirements you're gonna have to work a bit to reach a competitive set of gear (most regard that as Worn Sovereign which can be bought with gold from a vendor in the capital city, the full set requires RR70 and it's NOT hard to reach 70 anymore), but using golden scarabs can boost your stats a TON to make you feel a lot more competitive. Land of the Dead has vendors that sell weapons and the special talismans that go into them... they have no renown rank requirement and the talismans are crazy! Picture dual wielding swords with +96 melee power and 5% crit talismans socketed into each one. The weaps/talismans only cost golden scarabs, and you can dupe them in stacks of 9,999 (and you'll never even need half that many for a lifetime hahaha)! If I wasn't privileged enough to know how to dupe anything I need, I would never EVER put in the time or effort it takes to earn and farm all that crap. In the current state of the game, PvP combat is the only reason to play so why waste your time picking flowers??
Finally, and most importantly, Warhammer Online does NOT have any system for detecting this activity. They do not have the company resources to let CSRs hang around and look for people to check up on... They do not have a clue how to fix this huge flaw in the system and I guarantee it will never be fixed. The company has known of this method of duping since 2011, they have lost subscribers that are sick of the fact that it hasn't and WILL NOT be fixed. Knowing the details, I can only imagine it would be easy for them to put at least a half-assed bandaid on the problem and in 2 years they haven't even bothered to try. The only way that I know of getting caught is if you mail a large quantity of items to other characters. They seem to have a system that flags messages with large amounts of gold or large amounts of the same item attached. If you want to transfer stuff to your alts, be smart and invite the character to the guild so you can withdraw from the bank directly to their inventory. While I have way more experience in this area than probably anyone else in the game, I will not personally guarantee that you will not get caught. I will say that in my opinion and experience the risk seems pretty damn low (READ: NONE AT ALL AS FAR AS I KNOW) if you stay away from the mail. Still, exploit at your own risk. You should never exploit an online game unless you're prepared to face consequences, which in this case would be a permanent ban.
TL;DR - Warhammer players, ex-players, and potential subscribers/re-subscribers post, say hello, show interest... If I see a decent response I'll post everything I know about the mother of all exploits, the fabled DUPE, in all its glory.
