if you dont have ANY money, and you dont want to make ANY money, then this is the way...

1. get a fishing rod (I think luxury fishing rod works best)
2. get fishing skill (get a pink earth-worm first, talk to fisherman, and choose not to kill it)
3. use your fishing rod for ages for lots of magnets

If you have money and dont want to compound, here is the way

1. buy the magnest from players, usually around 200G each
2. pay me some money to thank me XD
