Training for the poor people...

Well, for a member, 1.6m really isn't too much.

Let's see, you can do what I'm doing to train for 99 strength, with a few adjustments.

I am killing skeletons in Damis' Lair, healing with Guthans. 1.6m is hardly guthans, but you can always use food! They'll cost about the same too (assuming you use Guthans as your regular armor too, like I do).

Also, have Throne to Miscellinia finished and put your citizens on 100% maples, 50% coal, you may also decide to take a little off coal and put some on fishing (cooked) for training food, although this isn't nessicary. Check every few days and sell the materials. The biggie are the birds' nests from the maples, an extra 1k every 100 maples PLUS whatever is in the nest. Getting a yew seed will pay for quite a few runs.

Use DBA spec, then drink a REGULAR RESTORE pot, then super attack, then super defense. In that order, although the last two don't matter. This way you get the effect of using a super set, but without needing super strengths. (Herb drops usually let you make your own restore pots, although they are cheap.) Runes and herbs more than pay for those potions, and if you are lucky, for some food too. Although you are really relying on your kingdom for that.

Good luck!
