Slayer is a basic skill, and if you want to make some money its a decent source. Go to the emote section and you will notice that it is a teleport menu, of which Slayer is on. It teleports you to the Slayer tower, get your slayer to at least 80 by clicking the chests over and over again. Then follow the path under the abyss demons, who drop whips. (=)) Get your combat and slayer up by killing these guys and there you go.
