Speak to Willus and tell him that you've got the armor and he'll give you a special publication. Equip the armor and jump in the water in which the monster went. Now you are RuneScape gold underwater and the monster is right in front of you. He's level 200 and utilizes melee attacks and an occasional magic attack.
He can hit in the 40's but such hits are infrequent, and a frequent hit is about 10 or 15. You can use lobsters but swordfish are greatest here. Make certain that you bring Prayer Potions, too. Once you have him 10 hitpoints use the book that Willus gave you to cast a spell that can finish him off. Once he is defeated he will fall Magical Bones. Take these to Willus to prove that you defeated the beast. Now speak to King Vargas and choose to tell him exactly what happened. Luckily Willus has already told him everything. Congratulations, quest complete.
I truly want some thing like a free for all stadium as a safe minigame. It could be quite fun and fantastic XP. The area would be about the size of the fist of guthix arena with lots of obstacles, ranging towers. . .etc. Like the FoG, arrows will be returned once you die. It won't provide runes, but it will return about 60 percent of the runes you have used.
Exactly like the arrows burst. Now there should be no such a thing as free XP. For in this region, you'll need to buy the Buy runescape 3 gold time you are planning to playwith. You could pay with either coins, FoG tokens, or runecrafting tokens, and other member's tokens.
