Bind

''This article describes definitions of various bind statuses of items. For a Character's resurrection location and its mechanism, see Spirit Binder.''

Most items found in the game have no limitations on selling, trading or mailing. However, some items are limited, being either permanently tied to an account or to a single character. These items are referred to as "bound" items. Once bound, most all items can never become unbound.

Unbound
Most randomly generated items are not bound to the character, and can freely be used, traded, mailed, and auctioned.
 * By using these items, they will suffer consequential permanent durability damage from a effect.
 * By spending Khyber Dragonshard Fragments, players can bind their equipment at the Stone of Change.
 * Unbound items become Bound to Character; Bound to Account items remain Bound to Account.
 * Category of items

Bound to Character (BtC)
Items that are already bound to a character and thus cannot be traded, mailed, or auctioned.
 * Bound items will not take permanent durability damage while repairing.
 * Category of items

Bound to Account (BtA)
Items that are bound to an account can only be traded to a character within the same account (and server) using a Shared Bank (available through the DDO Store). Bound to Account items cannot be mailed, not even to characters on the same account. Bound items cannot be traded or auctioned.
 * Introduced with Module 9.
 * Free to Play and Premium players must purchase Account Bank access to transfer these type of items.
 * Like Bound to Character items, BtA items will not take permanent durability damage.
 * BtA base items for Cannith Crafting do not change to BtC when Bound Shards are applied.

Binds on Acquire (BoA)
Items with this status become Bound (either to Character or Account), once taken from a chest or a reward list.
 * Most Named quest rewards and Named raid loot.
 * With Update 7, the game's UI shows whether the item becomes BtC or BtA.
 * Category of items

Binds on Equip (BoE)
Items on this status can be traded, mailed, and auctioned, but once they are equipped they become either Bound to Character (BTCOE) or Bound to Account (BTAOE).
 * All Green Steel items, when created in Altar of Fecundity.
 * Several items since Update 6.
 * Can be auctioned after binding, if you accidentally buy a bound item on the wrong character, you can auction it back to yourself.
 * BoE does not apply if the item is a weapon which is already BtA due to use of a sentient gem. Put a gem in first, then equip the weapon for the first time.
 * Note: Upgrading a Green Steel item at an altar within the Shroud will also bind the item to the crafter.
