The royal vault is the second royal building you receive in the game, immediately after the castle. As with the castle, all you have to do is drag the wand onto the royal vault to rebuild it. Also like the castle, you receive one experience point (XP) for rebuilding it.
The function of the royal vault is to store all of the items you collect in Castleville Legends. Every item you collect or craft must be stored in the vault, and every item takes up the same amount of space, whether it's a tiny blueberry or a large wooden shield. The sole exception is water, which seems to have its own, separate, unlimited storage in the sky.
Because of this peculiarity of the storage system in the game, many players find that storage is a continual challenge. I suppose this is part of the game's design.
The storage capacity of the royal vault starts out at 50 items, and may be increased in 10-item increments. Each time you increase the amount of storage, you must have a certain number of logs, Silver Vault Hinges and/or Golden Vault Padlocks. These are rare items which may only be obtained by adventuring in certain Places of Legend, or by purchasing them in the Sea Trading markets.
The number of hinges and padlocks needed for each increase are listed below:
|Increase storage to||Logs||Silver Hinges||Golden Padlocks|
Once you upgrade to 250 items, the requirements change a bit. While you'll still need locks and hinges to upgrade, the wood is swapped out for a combo of Stone and Iron Ore.
