Get 2 runescape accounts with less than a 50 level range in between them. Or a friend (TRUSED FRIEND).
This method works better if The Noobie (lower leveled) account does the killing.
Bolth players take 25003gp or a bit over 25k and go into pvp hotspot eg, the wilderness buy the water because there are not very many people there.
Get the lower leveled account to kill the higher leveled account. You Most likely will get 25k+ back, I average 75-125k.
Not working out well? try these 3 things to better your drops.
1 Every 30min you spend out of a pvp safe zone your drop percentage will increase. If of course you are risking 25k+ if you are not they will decrease dramatically.
2 Fight in a "Hot Zone"
3 Killing a higher combat level than you
I made a video that you can watch below, that is the reason there is no pictures, because i videoed it instead...
