Drop trick

The Drop trick is a process of getting multiples of an item that is otherwise restricted to having only one copy. For example, the Anti dragon breath shield: talking to the Duke of Lumbridge gets the player one shield, and he won't give any more after that. However, if the player drops the shield and asks for another one, he will give it. Then the player can pick the dropped one up and he or she will have 2 anti dragon breath shields.

This technique is used with many quest items that players want more of, either because they have benefits useful outside of the quest, to speed up the quest in case they lose something important along the way, or just to retain a copy.
