Armor Stand (BiblioCraft)
|First Appearance||MC 1.4.7|
The Armor Stand allows the display of armor. When right-clicked, it presents the user with an interface showing the armor currently equipped on the stand and on the user, as well as the user's inventory.
Without a redstone signal you can shift + click on the piece of armor you want to equip. Apply a redstone signal to the stand and all the armor will be swapped by shift + right clicking rather than just single pieces.
