Killing a Lesser and Greater Demon won't be much of a problem, Silverlight and prayer flashing (along with monk robes from the monastery), though, killing a Cockroach Knight might be a bit hard, considering they don't exist. I think that you meant Cockroach Soldier. Anyways, a nice idea, but you might want to work on your F2P list. PS: Killing a Revenant Knight is pretty hard in F2P (even normally). I couldn't think of anything hard for F2P, when I was f2p, lessers where a fairly easy challenge with gear, and i could kill a few greaters without too much problem. Someone else said cockroach knight in an earlier post, so I just thought the big ones where called knights, sorry about that. But yes, the F2P list needs work, I just am at a lack of ideas for it. Yeah my bad with the cockroach knight, i havent played in awhile. I killed a greater demon using this method last knight, took me about an hour and a half. I killed some men in lumby for some startup gold. Then I bought a bronze pickaxe, which i used to mine enough iron for full iron, smithed it in Varrock, then killed some guards outside falador for money, selling everything i got for more cash. Then i bought a fly fishing rod and feathers, along with a tinderbox and axe, and caught some trout and salmon at the barbarian village. Then i bought a team cape, and went up and killed a greater demon, the proceeded to get killed immediatly after by a Revenant Ork. Oh yeah i picked up leather gloves and boots in their spawn points in Edgeville and al kharid. And also, another idea for f2p, ive seen people talk about trying to get all the pieces for a skull sceptre in one run at the stronghold of security, so that could be another idea.
