In another MMO which I don’t name there is a very useful feature in the Warehouse:
I have a crafted item on my first char that I need to transfer to my second char, but I don’t want to give this item to other players acting as middle men because it’s an important crafted item, so I prefer the warehouse or a mailbox with attachments 
Yes! Why aren’t more people agreeing with this?! You got it, so you should use it, even if it is another character!
This is a must-have feature, I hope other people will share their opinions
I gave the same feedback earlier, but a current work-around is posting the item in the auction house for a weird price (high enough so it’s off the first few pages), then quickly changing characters and buying it off the other. You do lose a small amount of silver this way, but that’s the (better, imo) trade off versus having to use another player to trade it twice and lose 2 potential (instead of just 1).
That potential losing is also something i don’t understand. Just why?
I don’t think you should be able to give un-tradeable items to alts, but I do think that you should be able to transfer over any items or funds that you have. This would be fairly easy with an account wide storage.
To my understanding when you trade an item it loses potential(at least I could have sworn I read that somewhere), so as long as that rule still applies I guess it would be ok to transfer things between characters, considering you could only do it a maximum of 5 times.
I guess it is better then making everything untradeable. I accept your explanation.
In my opinion it would be nice to have something like that on the lodge for example, a box only yours chars could open and stuff. Just an idea.
isnt that what potency is for? you cant pass an item between characters forever but atleast let us transfer items between toons, even if it costs potency
But it seems you are not able to transfer items between your own chars. Are you?
It’s a suggestion to improve the game…
This is BS! Why can’t I trade between characters?
My characters share the same stupid “surname” or account name and friendlist, but not the storage… I don’t know what makes it so important to not trade between characters… My swordsman finds a lot of stupid bows and staffs which I can only sell to other players or rather to NPC, who give me money, and in the end everyone has billions of Zeny…
Instead I could use them for my other characters… but there’s no possible way to give it to them. That is… NO, just no. Make items tradable between our own characters please.
Also “potential” …wth. No one understands that. I gave a recipe to a friend so he could give it to my other character, and we learned that it can’t be traded anymore…
I agree 
I have a lot of stuff to my alter chars T_T
WTF with this game , i cant give my , MY items , to MY own characters , is this a real ? use token , and what ? 60 items , by 1 item in 1 time , OMG , IMC are you kidding ? wtf u do with this game ? im understand the f***ing market system , but my own characters cant do trade with itselfs ? pff , why u do this to us ?
An honest suggestion to help resolve the issue here would be to include a “Team Tradeable” option for certain items, which would allow them to only be traded through the Team Storage (which also needs some improvement, as one at a time and 200k for more seems silly to me; seriously Kafra was pretty awesome).
I agree that allowing all items to be tradeable (even just between teams) could cause issues with economy management, but the potential system (which is still active on retrieval of items from Team Storage) should be able to manage endlessly cycling good equips. If some items which the community believes should be ‘Team Tradable’ only have one potential now, which will cause them to not be retrievable from Team Storage, just make the potential on them two. This would only give us one trade, but that’s better than nothing. It would also continue to use the potential system as intended to minimize market saturation.
I also believe there needs to be a fair way to change premium (paid for with real money) items (consumable or cosmetic) between characters. I understand the reason we can’t do this currently is most likely so we have to buy the same thing twice if we want it on two separate characters. This probably applies more so to cosmetic items, but the point is still valid, the bottom line is important and IMC is still a business.
My solution for this is to allow swapping all premium items on one character onto another during character deletion. This ensures there is only one character ever in use of the items, but they are not lost to the void when a character is unwanted. For example: I buy a lot of Soul Crystal on Character A, but after many hours I get to the Class Circle I wanted to try and decide I no longer like that character and wish to start a new one. When I create Character B, I am fully aware I will never use Character A again, but all my Soul Crystal (which I paid real money for) are stuck there. After I press the Delete button on Character A, I should be asked which character to transfer my premium items to. In this case, I would select Character B. This would not harm the economy in game, nor disrupt that I need two sets of Soul Crystal if I want to use two characters. All it would do is protect the customer, inciting me to buy more premium items knowing they will never be lost to the void.
+1 Many other games you have a shared storage. It’s a basic feature.
Bump. This is a basic feature to have a shared storage just like Dragonnest so we can exchange items between our own characters.
