With the release of PvP worlds on 15 October2008, players began obtaining whole dragon square shields as drops from other players killed on these worlds. This increase in supply further depressed the price of the shield, down to its High Level Alchemy value of 300,000 coins. Although the shield was eventually removed from the PvP world drop list, its price has never strongly recovered.
The release of damage soaking on 14 December2010 gave the dragon square shield an edge over some of its competitors, many of which did not offer damage soaking bonuses. Damage soaking has since been removed from the game.
Low demand for the dragon square shield has reduced its price to the point that it costs 427,728 fewer coins to buy the shield on the Grand Exchange, or from another player, than to buy the right half from the Legends' Guild, receive the left half as a drop, and smith the two halves together. This lack of demand has reduced the price of the shield left half to approximately its alchemy value.
To buy both halves on the Grand Exchange and smith them together would cost 193,637 coins more than buying the shield itself (a loss of 2,582 coins per Smithing experience point).
For a time, the inventory sprites of the two shield halves could be put together to form a shape more closely resembling a kiteshield than a square shield. This was eventually changed by Jagex.
While it is rumoured that shadow warriors in the basement of the Legends' Guild have a higher chance of dropping a shield left half than other monsters, no evidence has been produced to support the claim.
