Dwarf multicannon

The Dwarf multicannon is a unique weapon in that it is not held in a players equipped inventory; rather, it is assembled on the ground. A player may only own and obtain a Dwarf multicannon after they have completed the Dwarf Cannon quest. After the quest, a player may buy all of the cannon parts from the dwarf engineer Nulodion, south of Ice Mountain, for 750,000 coins. The Dwarf multicannon cannot be used to attack players.

Setting up
The Dwarf multicannon is carried in four pieces while in a players inventory. To begin setting it up, the player must place the cannon base on a square that is vacant and whose adjacent eight squares are also vacant. The player must then use the cannon stand, cannon barrel, and cannon furnace on the cannon base. Finally, the player must use up to 30 cannonballs on the cannon.

Replacing it
The cannon deteriorates as it is used, and after a certain amount of shots are fired it will eventually disappear. When this happens, a player can go back and speak to Nulodion the dwarf engineer to get another one for free. A player can only have one Dwarf Cannon assembled at a time. A player will not be given another one if they simply put the cannon into their bank account and then talked to the engineer to get another. A piece of the cannon or a whole cannon can only be regained for free if it was set up when the player lost it. If, however, a player looses a cannon piece whilst it is in their inventory, either by dropping it or dying, Nulodion will charge a fee for the replacement part.
