So me and a friend are up at gdz on world 32 (F2P PvP) just stocking up some of my Sense Accounts for my old clan. I'm on Kecooler, a level 93 in full rune, and my sense accounts are two level 20s with no armour.
A level 60ish comes along with Zamorak robes (Useless) and a rune scimitar, plus various else/food. He can attack anyone. Me, I'm in full gear with food any my 20s both have 20 swordfish and are both 20 defence, one controlled by me and one by my friend Adam.
You're a level 60 with barely no armour and if you skull there's a guy in full Rune 33 levels above you ready to kick the **** out of you if you do. Do you decide to attack? Well he did. So when he skulled I proceeded to kick the crap out of him, and I don't think I hit anything less than 15 each hit.
The skill was to switch between windows and tank on my level 20 while at the same time attack on my 93. In the end...


I'd value that at 100k-120kish, not bad for me
