Dwarf multicannon



The Dwarf multicannon (or simply cannon) is a unique Ranged weapon. Unlike other Ranged weapons, it is not equipped by a player; rather, it is assembled on the ground. To use a Dwarf multicannon, the Dwarf Cannon quest must be completed. The cannon consists of four pieces: the base, the stand, the furnace, and the barrels. After a player has loaded cannonballs into the cannon, the cannon rotates and fires automatically. A player may fight using another weapon while the cannon is firing; thus, cannons are often considered to be a supplement to a primary weapon or fighting method. A player may own multiple cannons, but only one may be assembled at any one time. It is cheapest to buy a cannon from the Grand Exchange. Cannons are worth significantly less than 750,000 coins on the Grand Exchange because many people buy a cannon from Nulodion after completing the quest, and then later decide they don't want it and resell it. On 9 November 2009 the model for the cannon’s Grand Exchange set when dropped on the floor was corrected.

After completion of the Dwarf cannon quest, players may buy the full cannon from the dwarf engineer Nulodion, south of Ice Mountain, for 750,000 coins. Alternatively, the individual parts may be purchased for 187,500 coins each. The "Talk" option on Nulodion must be used to obtain the full cannon, whereas the "Trade" option must be used to buy the parts.

After the 17 November 2009 update cannons no longer waste cannonballs on NPCs in the process of dying. There is also an auto-setup feature.

Although the cannon is a very effective way of training Ranged, it is very expensive, and liable to make you unpopular with other players trying to train in the same area.

Assembly
The Dwarf multicannon is carried in four pieces in a players inventory. To begin setting it up, the player must place the cannon base on a vacant square surrounded by eight more vacant squares. The rest of the cannon will automatically be set up from there. Finally, the player must use up to 30 cannonballs on the cannon by selecting "Fire."

There are many locations where the cannon cannot be set up, including:
 * Ancient Cavern
 * Ancient Guthix Temple
 * Al Kharid Palace
 * Bandos' throne roomCannon.wmv.gif
 * Barbarian Assault
 * Castle Wars
 * Chaos Tunnels
 * Duel Arena
 * Dwarven Mine
 * Enchanted Valley
 * Fist of Guthix
 * Fremennik Slayer Dungeon
 * Feldip hills, red chinchompa hunting grounds
 * God Wars Dungeon
 * Ice mountain
 * Killerwatt plane
 * Kuradal's Dungeon
 * Lair of Tarn Razorlor
 * Mahjarrat Ritual Site Cavern
 * Mort Myre Swamp (this does not include the graveyard, where Dessous is located)
 * Pest Control
 * Player Owned Houses
 * Shade Catacombs
 * Slayer Tower
 * Stealing Creation
 * Stronghold of Player Safety
 * TzHaar City, TzHaar Fight Cave and TzHaar Fight Pit
 * Warriors' Guild
 * Water Ravine Dungeon
 * Zogre burial grounds

If a player attempts to set down a cannon base in any of these areas, a message will appear that it cannot be done. One message is Dark forces are preventing the dwarven construction from working. Another message mentions that the ground is too damp.

In other locations, the cannon may be set up but may be destroyed by an NPC almost instantly, or is almost useless due to limitations:
 * Certain quest bosses; for example, the Giant Roc will destroy a cannon if the player sets it up within its attack range.
 * Clan Wars; cannons cannot be used to harm other players, although cannons may harm their Summoning familiars.
 * The Kalphite Queen, and the King Black Dragon will destroy a cannon if a player attempts to use it.

Revolutions
After the cannon has been set up, loaded, and fired, the barrel will rotate and fire at target within its line-of-sight and range. The cannon barrel rotates in discrete intervals; there are 8 directions the barrel may face, and the barrel makes a 45 degree turn every 0.6 seconds, completing a full revolution in 4.8 seconds. The cannon fires one cannonball while facing each direction, so it fires up to 8 cannonballs per revolution.

In a single combat zone, the cannon fires at the monster the player is being attacked by. If the player is not being attacked by any monster – not being hit by any monsters – the cannon fires at multiple monsters. This means that a player can range, mage, or halberd from a "safe spot" in a single combat zone and have the cannon shoot at multiple monsters. However, the player will need to regularly come out of cover to reload the cannon. Alternatively, a player may just go hide and let the cannon do all the work.

In multi-combat areas, the cannon fires at every potential target within line-of-sight and range, even if the player is under attack.

Targets
For each direction the cannon faces during its rotation, there is a specific set of squares relative to the cannon's location that a cannonball may be shot into at that time. This target region can be visualized by a triangle emanating from the cannon barrel. Squares may be cut off from the target region by an obstacle.

Target regions for different directions overlap slightly. This may result in shooting multiple cannonballs at one monster in one cannon revolution, even one that is standing still. Up to two cannonballs may be shot at a monster that takes up a single square per rotation. If it is not in the proper location, however, only one, or even none, cannonballs will be shot per rotation.

Additionally, even more cannonballs may be shot at monsters that take up multiple squares. Monsters taking up multiple squares can be shot at using any of the squares that they are covering. For example, up to 4 cannonballs can be shot per rotation at a dragon because they are so big (3 squares by 3 squares) and if done correctly strykewyrms (also 3 squares by 3 squares) can be hit on all 8 rotations.

Players cannot control what target is chosen, thus it may fire at anything around it. However, if a player is already engaged in single combat, the cannon only fires at the current opponent. Also, in the Wilderness the cannon does not initiate combat against revenants that the player cannot attack directly.

Damage
The cannon hits up to 300 life points with each shot. For 10 life points done by a cannonball, 0.2 Ranged experience is gained. This is different from regular Ranged experience, where 0.4 Ranged experience and 0.133 Constitution experience is gained for each life point of damage.

It has been confirmed that equipment attack bonuses and ranged level affect your cannon's accuracy. The attack bonus that affects your cannon's accuracy will be whichever style of attack you're using; if you have 200 ranged bonus using range you'll hit very often, if you have 200 crush bonus but 0 ranged bonus while using a crushing weapon the range will play no effect in your accuracy and you'll hit just as often as if you had 200 ranged bonus using ranged.

Interestingly, despite being much larger and using larger ammunition, it seems to only have half the max hit of a hand cannon. This may be due to what seems to be an entirely pressure-driven system, as nothing but cannonballs need to be added to make the cannon fire. Another possibility is that a handcannon, as it is wielded by a player with at least 75 ranged, is capable of hitting deadlier locations such as the head, whereas the cannon is a fixed device. As to how the furnace is able to light without fuel or a tinderbox is unknown.

Decay and replacement
Cannons disappear after a certain period of time being continuously set up. 20 minutes after the cannon has been set up, a message appears that the cannon has almost decayed. 25 minutes after the cannon has been set up, or 5 minutes after the warning message, the cannon will decay (disappear). However, the decay timer can easily be restarted by picking up the cannon and re-assembling it again.

After an update on 3 December 2009, after the warning message, cannons' animations would change as to indicate that they were going to decay.

The decay effect is not based on the number of cannonballs shot, but based on the decay timer as stated above.

The cannon's decay is a one-time event, not a continuous degrading associated with declining performance, such as in crystal equipment (Crystal bow and Crystal shield). The cannon is equally effective at all times.

Cannons that do decay are not lost forever, but rather may be re-obtained for free from Nulodion. The fastest way to get to Nulodion is to cast Lassar Teleport (an Ancient Magicks teleport). Alternatively, players may teleport to the monastery using a charged Combat Bracelet and run to Nulodion, or they can choose to run from Edgeville or Falador.

Cannons will also disappear right away if they are set up and then you switch worlds. You can get them back from Nulodion in the same way as when it decays.

If a player dies while a cannon is set up, the cannon stays set up at the location. After it decays, it may be re-obtained for free from Nulodion. It is a common belief that cannons are lost upon death, but in this case the cannon may easily be re-obtained for free.

If a player dies while a cannon, cannon parts, or cannonballs are in the inventory, these items are lost, unless the player is able to re-obtain them from the gravestone. If you are under attack by a strong enemy that may kill you, immediately set up your cannon. If you do die, you won't lose your cannon.

Nulodion will not hand out a replacement cannon if the cannon or cannon parts are banked, set up, sold, or dropped.

Usage
Cannons are commonly used by players training Slayer to speed up tasks, in addition to obtaining Ranged experience. Cannons are less commonly used to train Ranged by itself, as Red chinchompas are faster Ranged experience. At about 400 coins per cannonball, the use of a cannon is often considered to be quite expensive. However, the cost is often considered to be justified by the bonuses of using a cannon. A player doing a slayer task can melee almost the entire time, getting nearly as fast melee experience as they would without using a cannon, but also get Ranged experience on top. The cannon will also attack several targets even in a single-way combat area as long as the player is not under attack, (e.g. in a safe spot)

In a crowded multi-combat area, such as the dagannoths under the Lighthouse, the cannon may produce a level of mayhem usually only achieved with Ancient Magicks spells. However, in highly populated multi-combat areas, the player will need to remain almost constantly by the cannon in order to reload it because large numbers of cannonballs will be needed, also, they will probably get negative feedback from other people fighting Dagannoths. This is aided by turning public chat to friends or off.

Since the removal of Pking in the wilderness more and more people will bring a cannon to areas which green dragons are inhabited. Even though these are single combat areas if the user is not attacking anything the cannon will attack any dragon that is not currently being attacked by another player. Because it's a single combat area players will not be able to attack dragons that the cannon has fired upon unless the cannon runs out of ammo or the owner of the cannon attacks a dragon. This has generally had negative feedback with most players who kill green dragons for the bones and hides for money. Many players have complained about this on the forums saying that cannons break single combat zone rules.



Cannons can also be used in bot prevention. If a player goes to the pure essence mine in Varrock and sets up a cannon within 3 spaces of the door, many of the players using macros will be stuck inside the shop until the cannon is gone. This is a very easy way to stop pure essence bots.

Trivia



 * The Cannon does not kill dwarves. It doesn't shoot at them.
 * The Dwarf multicannon, along with the Fixed device, the Cannon from Mobilising Armies, the Hand cannon, and the crossbow, are the closest things to firearms or modern weapons in RuneScape.
 * The only ammunition for cannons that players can use is cannonballs made from steel. However, Dondakan from the quest Between a Rock... fires Adamantite, Runite, and gold cannonballs from his cannon. In addition to that, in Quick Chat, it is possible to say, "I am smithing: [bronze/iron/steel/mithril/blurite/adamantite/runite] cannonballs."
 * Players may smelt cannonballs while a cannon is set up and not moving. However, if the cannon is rotating or firing, cannonballs cannot be smelted.
 * Instead of clicking on the cannonballs and using them on the cannon, you can just click on fire cannon and it will refill your cannon with cannonballs.
 * A glitch has been discovered that if someone steals a cannons target the cannon will still attack it. It has also been possible for the owner to help kill the target also.
 * Cannons may shoot twice, sometimes even four times, at the same target in certain conditions
 * Cannons cannot be used to fire at other players in any situation, even on PvP worlds.
 * Cannons may be used to fire at revenants, although the Wilderness level restrictions still apply.
 * If you leave a cannon firing in the wilderness and the cannon was hitting a revenant you will recieve a message saying that you cannot attack somone if you're not in the wilderness.
 * If a player gets a random event while the cannon is firing, players may still hear the sound effects of the cannon at work.
 * The cannon will not fire if a player is talking to an NPC via the enchanted gem. The cannon rotates, but does not fire any cannonballs.
 * Cannonballs will swerve to hit a target if the target is moving.
 * After the store update price of the cannon parts went to 187,500 each.
 * There is a glitch where you can hear the monster that your cannon is shooting at dying when you are nowhere near the cannon. This has yet to be fixed.
 * A glitch has been seen where a cannon's shadow remains ever after the cannon itself has degraded and disappeared. This produces a strange looking ground.
 * A glitch has been seen where the cannon will float in the air when it is close to higher ground.
 * The max hit of the cannon is 300, regardless of bonuses or skill levels (although bonuses do help accuracy)
 * When a cannon is near-decaying, it fires slightly different than normal.
 * When somebody attempts to set up the cannon near Red Chinchompa's the message "It would be dangerous to set this up now with all these spontaneously combustable rodents around" appears.
 * A glitch has been discovered where players are able to steal others cannons.
 * A glitch has been seen where players load the cannon with 31 cannonballs instead of just 30.
 * In Quick-Chat themed world, the warning message for the cannon decaying may not appear in the chatbox.
 * When fighting certain quest bosses, most players prefer having the cannon as a back up, because if you die ,and your cannon degrades, you can always claim another one free from Nulodion.
 * The cannon will shoot at a monster even if another player has just been attacked by the same monster, this has caused much grief as a player can be damaged and yet someone else's cannon attacks the monster.
 * Oddly, even though the Wilderness is the darkest place on Runscape the cannon is still allowed there and the message "Dark forces are preventing the dwarven construction from working." does not appear.
 * Oddly, if a cannon shoots at a monster above the cannon the cannonballs go through the hill or mountain the monster is standing on.
 * The boosts of a Full Slayer Helmet does not affect the damage of the Cannon.
 * Much to the annoyance of some other players, lower levels that have just completed the quest and obtained their own cannon have been known to set them up in the Grand Exchange, load them, and Brag.
