Dwarf Cannon
From Runescape Guides & Runescape Tips
The dwarf multicannon is a powerful ranging device made available upon completion of the Dwarf Cannon Quest. It uses steel cannonballs as ammunition, which can be made with a smithing level of 35 using steel bars and a cannonball mould.
When fired the cannon can produce massive amount of damage and spins around hitting all opponents giving great ranged xp. There is no level requirement to use it although the initial cost of the cannon itself is high. It can be purchased from players or the dwarven engineer (who will also replace lost/damaged cannons).
