Most of us have the ability to become a good player killer if we only knew how. Once you read this guide you will be on your way.
Mages
This is by far the easiest way to use any type of pure to player killing. The major thing though is you must have food that will completely heal your health so trout and salmon will be fine until you get about 20 health points. You must always use the highest spell, because you will have much better luck. The key to play killing with a mage is to get one team member only. This may vary if there are a lot of people around your level, but you must have a team member unless it is a one on one fight. Get another mage and you guys both need one hit on another and boom there dead. Hopefully you got the kill pick up. Then depending on whether or not you want to share, you'll need to go from there.
Melee
If you are going to be a pure melee all I can say is good luck. The key to being good at this would be a ton of strength pots. You never have an advantage one on one unless you have more food. When your level gets to about 30 or 40 and you're still pure is when you will have your fun. My advice is to get in bigger sized teams. You're best off getting more melees versus a lot of mages or archers because they will most likely not share with you.
Rangers
Buy the trout and salmon for your food. Always buy the best possible arrows and equipment, to give you the advantage. Even if you're in a team you're always best off getting the most damage on the opponent because you get the stuff obviously. In order to do best I use short bows, and rapid fire. I usually dominate the wild having everyone beg me for team. I seem to be the one controlling who's in and who's not. I believe archers have this advantage because they just dominate everyone.
Tips on Play killing
Spamming
Type in red what you say to distract them from seeing their hit points. (Warning may distract you too…)
Hit and Run
Most affective for rangers and magicians. Hit a person in the wild, and then step out. If you're just above Varrock wild though it is fine to stand behind the fence and hit melees because they can't hit you through it.
Falling In
Either have all your team mates step on the exact same spot as you so you look as one, or spread out throughout the wild so you're not all seen at once. Then a person will step in, you'll all see it and BAM.
Running away
Your arrows are not worth your death. If you are owned by someone just let them set on the ground instead of going out to get them and being hit a few more times. If you're losing it's not worth your time, or food so run.
