OSRS Dwarf Cannon Guide

Dwarf Multicannon Guide OSRS

The Dwarf Multicannon, also referred to as the Cannon, serves as a Ranged weapon within the realm of RuneScape. Completion of the Dwarf Cannon quest is a prerequisite for its use. In contrast to other Ranged weapons, players don't equip the cannon; instead, they assemble it on the ground. The cannon is commonly employed as a supplementary method to a primary weapon or combat strategy.

The cannon comprises four distinct components: the base, the stand, the furnace, and the barrels. Upon loading cannonballs or granite cannonballs into the cannon, it will automatically rotate and discharge projectiles.

It's important to note that utilizing the cannon to inflict damage yields only half the experience for Ranged (2 experience per damage instead of the standard 4), and it doesn't contribute to Hitpoints experience. The cannon's accuracy is heavily influenced by a player's existing equipment, attack style, and skill levels.

Post successful completion of the Dwarf Cannon quest, players have the option to purchase the cannon parts from the dwarf engineer, Nulodion, located south of Ice Mountain. Each individual part can be acquired for 200,625 coins. Nulodion also offers the full cannon set, which includes all four components, an ammo mould, and the cannon's instruction manual, at a cost of 750,000 coins through his dialogue. Should a cannon decay or if the mould is misplaced, Nulodion provides free replacements.




crafting Cannonballs

To effectively utilize your cannon, a substantial supply of cannonballs is essential. There are three primary approaches to acquiring cannonballs:

1. Self-Crafting: You have the option to create cannonballs yourself. This process involves utilizing a cannonball mould and steel bars. It's worth noting that cannonballs require a minimum of level 35 Smithing to manufacture. Unlike other smithing tasks, you'll need to use a furnace rather than an anvil. Simply have a steel bar in your inventory and interact with the furnace while holding the cannonball mould. Each steel bar will yield four cannonballs. Similar to smelting ores, you can opt to "make x" for a more efficient crafting experience.

2. Collaborative Crafting: If you have a friend who is interested in gaining smithing experience, you can provide them with the necessary steel bars. They can then craft the cannonballs and transfer them to you. This approach allows you to benefit from their smithing skills while contributing the required materials.

3. Purchase: Alternatively, you can procure cannonballs from the market. The cost of cannonballs can vary based on prevailing market conditions.

It's important to bear in mind that crafting cannonballs necessitates the possession of a cannonball mould and steel bars. Cannonballs can only be crafted at a furnace, and each steel bar utilized will yield four cannonballs. Your Smithing level must be at least 35 to partake in this process effectively.

types of Cannonballs


The Dwarf Multicannon is transported in a player's inventory as four distinct pieces. To initiate its setup, players should position the cannon base on an unoccupied square that is encircled by eight additional unoccupied squares. The remaining components of the cannon will automatically arrange themselves accordingly. Once in place, players can load the cannon with up to 30 cannonballs by using the cannonballs on the cannon, or they can choose to load it by selecting the "Fire" option. It's noteworthy that the capacity of the cannon can be increased by completing tasks within the Combat Achievements system. This capacity enhancement reaches a maximum of 60 for the elite tier. If a player holds both regular and granite cannonballs in their inventory, the granite cannonballs will be used first.

However, there are several locations where the Dwarf Multicannon cannot be taken into or set up. In instances where players attempt to place the cannon base in a restricted area, a message will appear in their chat box, explaining the reason behind the inability to do so. Below is an abbreviated list of areas where setting up the Dwarf Multicannon is prohibited:

(Note: For a comprehensive list, consult the in-game resources.)

It's important to note that this summary doesn't encompass all the locations where cannon setup is prohibited, and players should always refer to in-game information for the most up-to-date and comprehensive details.


Damage: The Dwarf Multicannon exhibits a consistent maximum hit of 30 when loaded with cannonballs and 35 when utilizing Granite cannonballs. This remains constant regardless of a player's Ranged level or any other factors influencing their ranged damage.

Accuracy: The cannon's accuracy is influenced by the player's accuracy bonus, which can be elevated through boosts. The calculation method varies depending on the weapon type and attack styles being used.

1. When employing ranged weaponry, the cannon employs the player's ranged accuracy, factoring in their ranged bonus. This encompasses enhancements from ranged accuracy-boosting prayers such as Rigour.

2. In scenarios involving melee weapons, the cannon employs the player's melee accuracy. This considers the stab, slash, or crush bonus corresponding to the selected attack style, in addition to their Attack level and other melee accuracy bonuses. This also encompasses melee accuracy-boosting prayers like Piety. It's worth noting that the cannon uses the player's crush bonus when no weapon is equipped, given that all unarmed attack styles are classified as crush.

3. When wielding Powered staves, such as the trident of the seas, the cannon's accuracy is determined by the higher value between the player's ranged and melee accuracy.

4. It's important to recognize that certain magical staves, like the staff of air, are treated as melee weapons even when autocast is enabled. The cannon's accuracy is rooted in the player's selected attack style's accuracy, but it's pitted against the target's ranged defense.

Revolutions: Once the cannon is assembled, loaded, and discharged, the cannon barrel undergoes rotation and fires at targets within its range and line-of-sight. The barrel turns at discrete intervals – it can face eight distinct directions, executing a 45-degree rotation every 0.6 seconds (equivalent to one game tick). A full revolution is completed within 4.8 seconds, enabling the cannon to fire up to eight cannonballs during this time. In terms of hourly output, the cannon can discharge up to 6000 cannonballs.

Within a single-combat zone, the cannon targets the monster that is attacking the player. If the player isn't being targeted by any monster, the cannon targets multiple monsters. This enables players to employ ranged, magic, or halberd attacks from a "safespot" within a single-combat zone, while the cannon targets multiple adversaries. However, players might need to periodically emerge from cover to reload the cannon if it's inaccessible from the safespot.

Engaging the Telekinetic Grab spell will momentarily pause the cannon's rotation and firing actions for the spell's duration.


The cannon rotates and shoots at targets within its range and line-of-sight.

Each rotation consists of eight directions, firing up to eight cannonballs.

Cannon accuracy is influenced by the player's accuracy bonus and weapon type.

In single-combat zones, it targets attacking monsters; otherwise, it targets multiple.

Cannonball placement depends on the cannon's rotation direction.

The target area can be obstructed by obstacles.

Larger monsters are hit on specific tiles (e.g., south-west for 2x2 monsters).

Targets near the cannon's corner can be hit twice per rotation.

Positioning matters for efficient targeting and multiple hits.

Player cannot control target selection; it may fire at any nearby creature.

If already in single combat, the cannon targets the current opponent.

Obstacles can block the cannon's line-of-sight and hinder targeting.


Cannons and Slayer tasks

Leveraging your cannon can significantly speed up your progress in completing slayer tasks, leading to quicker advancements in your slayer skill. It proves valuable for tasks that don't impose cannon restrictions. Two prime examples of favorable slayer tasks for the cannon are Dagannoths and Kalphites. Nevertheless, it remains beneficial even for non-multi combat monsters. Using the cannon often reduces task completion time by at least half.
