Just how cool a question of interest to me as well. I low alch with the explorer ring - but thats only because its free xp - although limited to OSRS gold about 30 per day. I use the nats I get to superheat ore. Not a priority with me to get runes,its a matter of luck for me. But I know there's a list of monsters and fall stats should you want to slay for a stack of nats?

I train slayer and overlook that which critter had the very best nat drops. . I know the roaches fall nats,but unless your into battling a lot then relying on this for nat generation is mighty slow. On the other hand - the rates are very low on things now and runes are inexpensive to buy when you've got the gp to but a mighty stack. I have only played because 08 and I believe that is the cheapest I've seen prices move. In the past I offered runes,but now I am burning them up as its not a large drop of cash to use the runes I have. At this time anyway - Though things changes... And I really anticipate this latest dumb upgrade to get figured out in our world. Until then im off to knock some gold loose from the critters butt. So here is how I'm fighting them: Inventory- A sheet of emergency food. Glarial's amulet so I can go in the waterfall to fight them. Fully charged games necklace to bank every now and then at the Barbarian Outpost.

So far, it's working very good and that I only need to bank when I can't hold any further drops. You're seriously better off with a whip instead of Guthan's warfare asses. The damage per second of the spear is awful, so only re-banking when you want to is faster. Switch into a whip if you don't need to heal then. Simple to solve.

Helm: Total Slayer Helmet - While I'm not killing them for a slayer job, the Total Slayer Helm supplies excellent defence to get a ranged helm, as well as cheap RS gold provides a bonus to ranged attack, even when I do not receive the 15% incentive since it isn't a slayer job. Amulet: Armadyl Pendant - Inexpensive Armadyl item. I currently have an offer in for an Armadyl Stole to substitute it, but it likely will not buy for just a tiny bit.
