I have to disagree with the above. You can definately still pk. Piety is very powerful, I have freinds with 86 strength hitting better than me (99 strength) simply because they have piety. All you need is 90 attack or higher (+ piety = ownage), 86-90 strength, a high enough mage level for ice burst but preferably ice blitz (i find burst more reliable at hitting, and I'm 99 mage even) and 86+ ranged with decent bolts. Don't underestimate piety. It is your friend. And don't beleive the hype that you need 99 strength, with a torso, fire cape, defender, rune boots, rune gloves and piety you will be KOing pures like they were not even there. I'm 45 defense. I'd love to have 70 def and prayer, but that would make me 100+ since my range, mage and strength are already maxed. HP almost too.
