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 (use Talk option for whole cannon, Trade option to get individual parts for 200,000 coins each). Note that it is a better deal to buy the multicannon set from the Grand Exchange, with the price right around . The Dwarf multicannon cannot be used to attack players. Also note that the Dwarf Multicannon's range damage only gives half the experience points than regular ranging and provides no hitpoints experience.

Assembly
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.

Areas where the cannon cannot be set up:
 * Ancient Cavern


 * Barbarian Assault


 * Castle Wars


 * Certain quest bosses, for example the Giant Roc, will destroy your cannon if you set it up in their attack range.


 * Chaos Tunnels


 * Clan Wars


 * Duel arena


 * Dwarven mines


 * Enchanted Valley


 * Fist of Guthix


 * Kalphite Queen, the King Black Dragon, and God Wars Dungeon generals. All of them will destroy your cannon if you decide to use it.


 * Mort Myre Swamp


 * Pest Control


 * Shade tombs


 * Slayer Dungeon


 * Slayer Tower


 * Stronghold of Player Safety Dungeon


 * TzHaar City


 * TzHaar Fight Cave and TzHaar Fight Pit


 * Warriors' Guild


 * Wizards' Tower


 * Zogre Burial Grounds


 * Stronghold of Player Safety

Use
After the cannon has been set up, loaded and fired, the barrel will rotate and fire at every potential target within line-of-sight and range. It can fire at any number of targets with each rotation, except if the player is under attack in a single-combat area, then it will fire only at the attacker and only once per rotation. If a player takes cover after firing their cannon, they can effectively turn a single-combat area into a multi-combat area. However the player will need to regularly come out of cover to reload their cannon. In multi-combat areas, the cannon will fire at every potential target within line-of-sight and range, even if the player is under attack.

The cannon deteriorates while firing, until eventually disappearing (300 shots without picking it up and reassembling it again). When this happens, go back and speak to Nulodion, he will give you another one for free. You can only have one dwarf cannon assembled at a time. You will not be given another one if you simply put the cannon into your bank account and then talk to the engineer to get another.

The cannon can hit up to 30 with each shot, so in a crowded multi-combat area the cannon can produce a level of mayhem usually only achieved with high-level Ancient Magicks.

Since the cannon fires at multiple targets, it has the fastest attack rate of all Ranged weapons, only rivaled by the explosion of the chinchompas and red chinchompas. In the RuneScape Knowledge Base, its attack speed is represented by the following animation:



Note(1) that sometimes a cannon will fire at a target twice per rotation. However, on the RuneScape FAQs, it says that this is intended to happen, and is not a glitch or a bug. This is not anything any cannon owners are likely to complain about.

Note(2) a cannon can't fire at multiple targets standing in 1 line. If this happens the cannon will only hit the first target. So don't think you will hit 10 monsters if there are 10 monsters close to you!

Replacement
The cannon decays as it is used, and after about 400 shots are fired it will decay completely and disappear. A player will get a warning that it is about to decay. If the player picks up their cannon and reassembles it, before it disappears, the cannon will be good for another 400 or so shots. Unlike crystal equipment, the cannon's performance does not decline as it comes closer to disappearing.

When the cannon does decay, 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 loses a cannon piece whilst it is in their inventory, either by dropping it or dying, Nulodion will charge a fee for the replacement part.

Players can use the decaying feature to their advantage, to save on inventory and bank space, by deliberately letting the cannon decay when they are finished with it. This way Nulodion can effectively store it for them until they need it again.

If you do not wish for your cannon to decay then put it in your inventory often (placing the cannon in your inventory will renew it so the cannon will not rust and you will not have to replace it).

Trivia

 * This, along with the Fixed device and crossbow, is the closest thing to a gun in RuneScape.
 * While the only ammo for this device that players can use in training is steel cannonballs, Dondakan in the quest Between a Rock... manages to fire Adamantite and even Runite cannonballs.
 * You can smelt cannonballs while a Multicannon is set up. However, if it has cannonballs in it, and is rotating/firing, you cannot. Whether this is intentional or not is unknown.
 * Just like how you can't use the multicannon against players, dwarf multicannons will also not fire at revenants.
