Dwarf Multicannon

Nulodion, the dwarf cannon engineer at the dwarves' mine on Ice Mountain, sells a multicannon for 750,000 coins. The cannon comes in four parts: the base, the stand, the barrels and the furnace.

Setting it up

Set the base down on open ground, then add the stand, the barrels and the furnace in that order. You can run one cannon at a time. Some places refuse a cannon, such as the dwarves' mine and the banks.

Firing

Load the cannon with cannonballs, up to 30 at a time. It turns in a circle and fires at the creatures around it, with a maximum hit of 30. Each point of damage it deals gives you 2 Ranged experience.

Cannonballs are made from steel bars: heat a bar in a furnace with the ammo mould in your inventory.

Losing it

A cannon left standing decays after 2,500 ticks, about 25 minutes. Some creatures can destroy it. Nulodion replaces a lost or decayed cannon for free, and a cannon you gave away or dropped is not replaced.
