Signs of the porter are pocket slot items craftable with the Divination skill, which automatically teleport collected items to your bank. Every time an item is teleported to the bank, one charge is used on the active sign. When a sign is out of charges, it disappears.
The sign becomes active when it is equipped, and it can be deactivated by unequipping it. It will disappear when its charges have expired. Items are sent to the bank when they are obtained from a skilling action, or for items in the 'Other' category (see below), when they are picked up off the ground (which includes combat drops, such as dragon hides). Not only drops from monsters can be banked, but also items that a person was carrying in the Wilderness will be banked if the player picks up the loot while having an active sign.
Urns will still be filled while collecting with an active sign. If the Varrock armour ore doubling effect is activated, the second ore is also banked. Shooting Star reward that doubles an ore will also be banked. Mining two ores from a concentrated coal or gold will bank both but only use one charge. When fishing shark, if you catch two, both are banked at no additional porter charge. If you do not have any space in your bank, the items you collect remain in your inventory.
If a stone spirit appears, the spirit's banking takes higher priority than the porter's effect.
