The substance to make it's a rare ore that OSRS gold can only be found underwater. Get your swimming gear and have Murphy bring you underwater. Close to the crabs is a crack in the rock which you can go via (50 Agility required) for an underwater mine which gets the ore you want. Mine about 25 of them and then head back to Willus. He gives you a Magical Chisel. Melt the ore in a furnace and then use the Magical Chisel on the ore to make bits of it. You need 60 Defence to utilize it.
Speak to Willus and inform him that you've got the armor and he will give you a special publication. Equip the armor and then leap in the water where the creature went. Now you're underwater and the creature is right before you. He's level 200 and uses melee attacks and an occasional magical attack.
He can hit at the 40's but these hits are infrequent, and a frequent hit is around 10 or even 15. It's possible to use lobsters however swordfish are greatest here. Be sure that you bring Prayer Potions, as well. As soon as you have him 10 hitpoints use the publication that Willus gave you to cast a spell which can finish him off. Once he is defeated he'll fall Magical Bones. Take these to Willus to prove that Runescape 2007 gold you conquered the monster. Now speak to King Vargas and choose to inform him exactly what happened. Luckily Willus has told him everything. Congratulations, quest complete.
