The Voidwaker is a melee weapon that requires level 75 Attack to wield. It is acquired by having Madam Sikaro in the Ferox Enclave Dungeon reassemble the Voidwaker blade, hilt, and gem for a fee of 500,000 coins, which are obtained as rare drops from Vet'ion, Callisto, and Venenatis respectively (or their lesser counterparts).
