Bind

Bind is a term used to define how a particular item is linked to an individual character. Not all items bind, especially low-quality items, and these may be equipped, used, unequipped, and then either sold to a vendor, traded, or posted on the Auction House. Items that become permanently bound to a character are called "soulbound".

Types

 * Bond on Equip: This mean an item will permanently bind to a character only when that character puts the item on. If the item is unequipped, it may only be sold to a vendor or disenchanted by the character it is bound to. If the item is not equipped, the character is free to sell or trade it.
 * Bind on Pickup: This means an item will permanently bind to a character when the character picks it up. Note the item never needs to be equipped for it to bind. This distinction is especially important when rolling for items in a dungeon or raid. A warning will appear to players when attempting to pick up the item.
 * Bind on Use: This means an item is permanently bound to a character only when they use the item.
