Dragon sq shield

The Dragon Square Shield (Dragon Sq Shield) is a rare piece of armour and among the best shields in the game. It is found in two halves, which can be merged by using them with a hammer and anvil if you have level 60 smithing. The Shield right half can be purchased in the Legends' Guild for 750,000 coins after completing the Legends Quest. The shield left half, however, must be obtained as a rare drop from any monster that drops gems.

It is also worth noting that, being a square shield (rather than the ever-popular kiteshield), the Dragon Sq Shield does not incur a negative magic defence bonus.

Trivia

 * Vannaka, the Combat Instructor and Slayer Master, wields a steel two-handed sword along with the dragon square shield at the same time.
 * It is interesting to note that, originally, the individual images of the shield's right and left halves combined would have resembled a kite shield rather than a square shield. This was eventually remedied by Jagex.
