Winds of Waiko is a Ranged weapon that was originally obtained by completing the "voyage" around the Wushanko Isles seven times in the Beyond the Arc promotion from Treasure Hunter. The weapon can use standard arrows up to dark arrows. This bow cannot be used in Barbarian Firemaking to light a fire, nor can it fire ogre arrows or brutal arrows.
It can be purchased from Boni on Waiko for 25,000 chimes and 50 taijitu. If lost or destroyed, a replacement can be purchased from Diango for 2,000,000 coins.
