He can hit in the 40's but such hits are rare, and a frequent hit is about 10 or even 15. You can use lobsters however swordfish are best here. Be certain that you bring Prayer Potions, too. As soon as you have RuneScape gold him at 10 hitpoints use the publication that Willus gave you on him to cast a spell that will finish him off. After he is defeated he'll drop Magical Bones. Take these to Willus to demonstrate that you conquered the monster. Now talk to King Vargas and choose to inform 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 really fun and fantastic XP. The area would be on the size of the fist of guthix stadium with lots of challenges, ranging towers. . .etc. It won't supply runes, but it will yield about 60% of the runes you have used.
Just like the arrows break. Now there shouldn't be any such a thing as complimentary XP. To get in this region, you will have to purchase the time that you intend to play. You could pay with coins, FoG tokens, or runecrafting tokens, along with other member's tokens.
Just to make it fair for the people who have a hard time earning money. Bandages could be supplied along with a milder version of their strength potion. The area can be divided into to sections: Place with levels (like the wild) in which you can just attack opponents near your level. A free for all area.
I think there should be no need for rewards as it'd be pretty interesting how it is. For people not to acquire super fast XP by 1 hitting noobs each day Buy RuneScape gold you could get a smaller quantity of XP gained (similar to fighting random events).
