Have you considered the value of bonds on the hard mode? Unless you bought them with actual cash (in which case what does it matter, you can do that on hard mode), bonds aren't going to sell for what they sell on normal mode.
What are the bosses/monsters in OSRS that specifically can't be killed without a task?
