Dwarf multicannon

Unlike any other weapon in the game, the Dwarf multicannon can hit up to 30 points of damage consistantly against a group of monsters regardless of their level. The cannon is also a useful tool for slayer tasks as it inflicts high amounts of damage quickly and revolves upon its base, firing upon anything attackable in the set-up area

The cannon cannot be created using the smithing skill or any other skill in the game. Instead, it must be bought from Nulodion the dwarf near the entrance of the Dwarven mine after the completion of the quest: Dwarf Cannon.

Because the dwarf multicannon does not give any Hitpoints experience, some pure accounts use it to train the Ranged skill. This is incredibly useful to those who wish to train ranged alone as it does not give any other experience other than ranged while it is being used.

The cannon requires cannonballs to fire which both can be bought from other players, or made with the smithing level requirement of 35. An Ammo mould and a steel bar are required to produce this ammunition; one steel bar will produce 4 cannonballs each. Please note that the quest Dwarf Cannon is required to make the ammunition as well as use the cannon itself.

Cannon parts
The cannon consists of four separate pieces (excluding the required cannonballs) which must be used on each other to set up the cannon.

First, the Cannon base is placed on the ground. Then, the Cannon stand is added to the base, followed by the Cannon barrels. The last peice to be added is the Furnace, which powers the Dwarf Multicannon.

Cannonballs are then used on the cannon, and the right-click 'fire' option is selected. This will cause the cannon to rotate and fire at anything attackable in the set-up area.
