Lol I would be happy to help you out Alister
When I head to Pk, I first decide what type of attacking I would like to use such as: Melee, Range, or Magic.
I usually use either Melee or Range.
When i'm using Melee, I wear Full Dharoks w/ Great Axe, Dragon Boots, Barrows Gloves, Fire Cape, and a Strength Amulet. Full Dharoks is a critical part when I Pk mostly because it can hit high when you have the full set. I also bring with me a Crystal Bow in case I find a place to range, and a full Inventory or mantas.
Now, when I get to the Pk-ing place, whether it being Funpk, Teampk, or Strpk,
I ALWAYS MAKE SURE THAT MY HP IS FULL, because I hate being killed with just one hit.
When I am fighting, I always check my hp constantly to make sure that I will not die in the next blow from the enemy. When my hp starts to get low, I have to do some thinking. If the enemy is wearing full Dharoks, I check his combat level as it decides how high he can hit. I usually stay above 40Hp as some people can hit 50's+.
I usually just keep this strategy up until I run out of food, where I then go berserk and try and kill everyone in sight
Hope it helps
