Royale dwarf multicannon

The royale cannon is an cosmetically upgraded version of the gold dwarf multicannon, released on 8 March 2011. In order to purchase the upgrade, players must participate in the Artisans Workshop until they have 100% respect, then speak to Elof with all four parts of a Gold dwarf multicannon in their inventory.

This upgrade cannot be applied to normal dwarf multicannons - players must first purchase the gold dwarf multicannon upgrade for 50% respect - effectively making the true cost of the royale cannon 150% respect. The royale cannon consists of:
 * Royale cannon stand
 * Royale cannon base
 * Royale cannon barrels
 * Royale cannon furnace

Trivia

 * In the game guide, a picture of the royale cannon is captioned "Dwarfs must use the metric system", which is a reference to an iconic scene from Pulp Fiction wherein the characters discuss how a "quarter-pounder with cheese" is called a "Royale with cheese" in Europe, and one asks if that's because Europe use the metric system.
 * All pieces of the cannon have an items kept on death value of 1 coin except for the base, which has a value of 187,500 coins, which is equal to the store price of a normal cannon from Nulodion.
 * When placed on the ground and right clicked, the Royale cannon is called "gold dwarfcannon"
 * While the upgrade was intended to be cosmetic only a glitch existed that allowed a royale cannon to be used in both the Chaos Tunnels and Kuradal's Dungeon. This has been fixed in a hidden update.
