Safe

The Safe is a portable storage item with 40 slots to store other items. The Safe, Piggy Bank, and have the unique ability to be carried while they contain items. It is purchased from the Merchant for each, after Skeletron has been defeated.

The Safe functions identically to the Piggy Bank, except that it is larger and does not require a platform or furniture surface, and can be placed directly on Blocks.

Differences from Chests
The Safe (as well as the Piggy Bank and Defender's Forge) functions similarly to other storage items, but with some important differences:
 * Each Safe contains the same items (when accessed by the same character), no matter where they are placed within the world. Purchasing multiple Safes will not give you more space, but will offer more points of access to your Safe contents.
 * The Safe can be picked up even when it contains items. This makes it a viable way to expand your character's inventory slots. It must be placed in order to add or remove items, and can be freed again with a Pickaxe.
 * The Safe's contents are saved with your character data, instead of the World data. You keep its contents with you from world to world, and from server to server.
 * The Safe's contents are exclusive to each player, so other players will not have access to items you store there. This makes it useful for item security on PvP servers where stealing is allowed.
 * Multiple players can use the same Safe without having access to each others items. Each player will only see their own items when accessing the same Safes.
