To start off this guide, you will need to make a new character. I suggest a badass, and intimidating one, like “x Pwnage Pure x”. The name is all too important. You hardly ever see a person that is good at pking named “army5632”, or whatever you may think of.
When you are Pking, or even training, you need proper supplies. For levels 1-30 range, I suggest buying about 3k bronze arrows and proper ranger attire. For 31-50, I suggest steel arrows. Make sure to have some lobsters if you want to train on bigger monsters.
To start training, head over to the monk monastery that is a little northwest of edgeville. There, you can kill level 5 monks with 15 hp each, and if you get hurt, you can ask them to heal you. Do this until about 30 range. When you think you are ready to move up a little, my advice is to go to the Varrock sewers, and train on the zombies from across the little stream. Shown below is a map of the Varrock sewer system, and a red dot path showing where to go to train against the zombies.

Train here until about level 50 range. This may take a few hours, maybe even a day topps, but when you are done, you will have a major choice to decide.
Now that you are at 50 ranged, pat yourself on the back! You made it! You now have the option of becoming a member and using a magic short bow. If you do choose to become a member, train in a mini game called “Pest Controll” until desired ranged lvl, and begin to stake or PK. If you decide to stay non-member, You can still have some serious pownage. When you reach about 60 range, I suggest getting 40 attack and about 50 strength and use a rune 2 hander with your bow. It is an awesomely effective strategy. Search “Range/ rune 2h pker” on
YouTube
to see some proof.
