RuneScape released a dragon crossbow with the evolution of combat update. This item was initially untradable, and RuneScape players had to obtain it either as a drop or by buying the materials. Then they needed level 94 fletching to assemble the dragon crossbow by adding a crossbow string to an unstrung dragon crossbow.
Dragon crossbows were made tradable on January 14th, with the monster buff update. All three variants have steadily risen in price since their release.
Dragon two handed crossbow debuted at about 14 million coins. Dragon crossbow debuted at about 12.5 million and dragon offhand crossbow at 15 million.
RuneScape players can weigh the pros and cons of each weapon and decide upon what one they want. Alternately, they can opt for chaotic crossbow or royal crossbow, both which are popular.
Dragon crossbows do not degrade, so the only drain on the RuneScape player's bank is the initial cost and the cost of ammo used.
