Um it's about 17k Points I calculated few weeks back.
It will take you few months while you can just use Soul Wars where you can get to 99 in a week.
You might think, well soul wars Script cost money and I can't afford it.
Well just think about it, your paying $5 a month for Runescape, and you are planning to use that month (OR MORE) to bot PC which means you are basically paying that $5 for PC script. Soul Wars Script cost $5 and it's MUCH fast XP and you can have few skill up to 99 in a month with Soul Wars script.
Logic? Now? you decide
