Account-wide Storage: The Xunlai Chest
The Xunlai Chest is storage space for all of your characters to share. To set up your storage, talk to a Xunlai Agent (found in most towns) and, for a mere 50 gold, they'll give you access to your very own storage chest.
In the chest, you get one pane of 20 slots to start, plus an additional pane for each campaign and expansion you own. This means you can have up to four storage panes for your account. For another 50 gold you can add an extra pane of materials storage, which only holds stacks of crafting materials.
One you've set up your storage, each of the other characters on your account will need to pay a one-time fee of 50 gold to the Xunlai Agent before they can access the chest.
Additional Storage: Extra Storage Panes
If you're still running out of room to hold items, you may also purchase up to four additional panes of extra storage from the In-Game Store, or at the NCsoft Store.
You'll see any panes you buy the next time you open your chest. If you acquire extra panes while running the game, you'll have to restart before you see them.
