He can hit in the 40's but these hits are infrequent, and a frequent hit is about 10 or 15. You can use lobsters however swordfish are best here. Make sure to bring Prayer Potions, as well. Once you have him at 10 hitpoints use the publication that Willus gave you to cast a spell that will finish him off. Once he is defeated he will fall Magical Bones. Take these to Willus to prove that you conquered the monster. Now talk to King Vargas and choose to tell him what happened. Luckily Willus has told him everything. Congratulations, pursuit complete.
I truly want something like a free for all arena as a secure minigame. It could be really fun and great 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 will NOT supply runes, but it will yield about 60 percent of the runes you've used.
Just like the arrows break. Now there shouldn't be any such a thing as free XP. For in this area, you'll need to purchase the time that you are planning to playwith. You can pay with either coins, FoG tokens, or runecrafting tokens, and other member's tokens.
Simply to make it fair for the men and women who have difficulty making money. Bandages could be provided together with a milder version of their strength potion. The place could be divided into to sections: Area with levels (such as the wild) where you can only attack opponents near your level. A free for all area.
