So, I recently found out about doing masses of easy clues from H.A.M members. I went to try it out, and found to my surprise that even ignoring the scrolls (which I did not) I was making a fair amount of money + exp by just alching the slayer staff drops. Are there any other relatively unknown places that are a nice balance between exp, money, and interesting stuff (i.e. clues)?

Most people arent gonna give out their secrets on an open forum, otherwise they wouldnt be secrets. My best advice is to just try different things that come to mind, and see what works the best.

 

Also, last i heard, killing snakes and banking their hides was decent xp and gp, but dont quote me on that

I'll tell you after I've single-handedly made the market crash.

On a side note, inside the H.A.M place, after advancing through the quests series there's an addional area inside a trapdoor you can enter. Thieving from the H.A.M members inside gives keys to chests in there as well. The loot in the chests is fairly good, lots of jewelry.
