The interface that appears over the player's inventory.
Open allows the player to access its inventory directly, similar to the Looting bag interface except that the player can withdraw and rearrange the contents freely. Similarly, the interface closes if the player performs any action, is hit in combat, or many other situations.
Withdraw-1 removes the first item from left-to-right, top-to-bottom. This cannot be done if the player's inventory is already full, unless the item is the only item remaining in the supply storage.
Withdraw-all works similarly to Withdraw-1 except that it continues to remove items until all are withdrawn or the player's inventory fills.
Resupply restores any partially-used items in the player's inventory by using the items contained within. For instance, Smelling salts (1) becomes a Smelling salts (2) if another Smelling salts is stored in the supplies. This option only restores items already in the player's inventory; it does not remove any new items.
Using a removed item on the supplies returns it to the inventory into the first empty slot (left-to-right, top-to-bottom). If all items are removed from the supplies, the item is destroyed, and a message will appear in the game chat stating "The bag disintegrates.". A new one may be obtained from the Helpful Spirit after completing another two paths.
