I don't know much about pking.
Stats:
Attack: 79
Defense: 77
Strength: 80
Magic: 73
Range: 82
Prayer: 65
HP: 82
Summoning: 57

Is that good or bad?
And, if it's bad, can I somehow change it?
If it's good, can some one help me out with learning how to pk?
All I know is don't die, and eat.

Well, you have a few options..
Melee get 70 prayer, do knights waves so you can use piety, then go pk see if it's hard for you.
Also one of the best things for PK is Vengeance, but Idk if you wanna spend along time + lots of cash, you can pk without it.

Ranger- for ranging to be affective against people your level it has to be high, ~90-95 and venge is highly recommended..

I can use piety, I just don't have the prayer level for it.
So, 70 prayer, 90 range, 94 mage, should I get strength up at all?
And, what would be some good gear with which to PK in?

EDIT: TBH, I don't really know how to pk at all.
So, if anyone could help me, or point me to a guide, that would be great.
(I sadly cannot watch videos on my computer)

You could be quite a good pker if....u got 94 mage for vengance, bought claws for spec weapon or ags.

Well, I can't get them, since I don't have that much money.

Pking takes alot of money to start up, but its extremely profitable. I say at least get dds + whip. But he's right really.

I know a way to get 94 magic, but I meant claws or an ags.
I have a dds, and a whip, and I'm training up attack, defense, and strength now, so I can go pking.
I'll have to research some guides on it though.
