Plankmake is over 140k per hour, I've gotten that rate personally. I've heard it can be 160k per hour, but no personal confirmation on that. Wouldn't firestriking overnight be considered afk training and therefore be reportable? I would like I maintain that rock lobs are the best method in the long run. It's very cheap given the benefits of it. Of course, money is an issue. But if it's an issue now, it'll be an issue later when you get up summoning. Better wipe the entire floor in one go, and you'll most likely save time/money. Still, if you are stuck for cash you can follow what was mentioned above. I'd like to add that casting Onyx enchanting in MTA is 80k+ per hour. I find it enjoyable, but that's just my opinion. You lose 1 cosmic rune per cast, but each invent you deposit gives you 1 death, blood, or cosmic as bonus. You can also buy cosmics with your points from the Reward shop, but that process is too tedious since there's no Buy-X, it's only a Buy-1.
