Porter

Signs of the porter automatically teleport collected items to your bank (urns still work). If the Varrock armour ore doubling effect is activated, the second ore is also banked (since 10th September 2013). If you do not have any space in your bank, the items you collect remain in your inventory. 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.
