Speak to Willus and tell him that OSRS gold you've got the armor and he will give you a special publication. Equip the armor and jump in the water where the creature went. Now you are underwater and the creature is right in front of you. He is level 200 and uses melee strikes and an occasional magical attack.
He can hit in the 40's but these strikes are rare, and a common hit is about 10 or 15. You can use lobsters but swordfish are best here. Make certain that you bring Prayer Potions, as well. Once you have him at 10 hitpoints utilize the publication that Willus gave you to cast a spell which will finish him off. Once he's defeated he'll fall Magical Bones. Take these to Willus to prove that you defeated the beast. Now speak to King Vargas and decide to tell him what happened. Fortunately Willus has already told him everything. Congratulations, quest complete.
I truly need something like a free for all stadium as a secure minigame. It could be really fun and great XP. The area would be about the size of the fist of guthix stadium with lots of obstacles, ranging towers. . .etc. Such as the FoG, arrows will be returned once you die. It will NOT provide runes, but it is going to return about 60% of the runes you've used.
Exactly like the arrows break. Now there should be no such a thing as complimentary XP. For in this area, you'll need to buy the time that you are planning to play Buy RS gold. You can pay with coins, FoG tokens, or runecrafting tokens, and other member's tokens.
