Tradeskill Depot

Your account will gain a Tradeskill Component Depot that can hold 250 stacks of different tradeskill items. You can add slots with marketplace items as you need them. This depot is shared among your characters on the same account and server, like a shared bank. Each of these slots ignores the standard stack sizes and can hold significantly more of each item. Additionally, you can utilize these items anywhere in the world when crafting.
