i have about 270 slayerpoints, and wanted to know the quickest and easiest way to get to 400 points. I am lvl 111, i heard that some guy knows how to do it in 3-4 hours but he wouldn't tell me.
The fastest way is to do the Burthorpe master for 9 tasks, then on the 10th task do the best slayer master you can use to get the bonus. If you are quick, you can do one Burthorpe task in 5-10 minutes, meaning it's about an hour in between the 10th task bonus.
Errr, whoops, I guess he does. In that case, use Mazchna, the Canifis master. Sorry, it's been a long time since I have used any master other than Kuradal. :3
