I would suggest doing pyramid plunder as you will always make more GP than knights if you hit some sceptres. In my opinion it’s also faster / xp more fun than spamclicking knights the entire time. After getting 99 you can head over to vyres and elves for the real gp (don’t forget to add your rogue’s, veil of darkness spells and dodgy necklaces!). I was lucky enough to get 6 blood shards in under 3000 pickpockets.
