Hi, wilbur298 here and this is my guide to Fast and Easy money.
The way is crafting.
Do the following for Fast and Easy money:
Trade dommik, and buy a chisel.
Then get 100m in you inventory. (you don't need 100m if u don't have just get about 10m.)
Next, buy the rest of you'r inventory of saphires.
Use the chisel on the sapphires, and once you get a full inventory just simply bank the amulets.
Continue doing this and repeating.
Once you are 40 crafting move up to emerald's and do the same thing except with ruby's.
Here is a list of the levels you need:
Sapphire-1
Emerald-40 (I think i just did sapphire's untill 50.)
Ruby-50
Diamond-70
Dragonstone-75
There is one more gem (a onyx) but i didn't put since dragonstone is what u need for money.
Once you get 75 make amulet's of glory, then sell to vannaka (the slayer peson) for 5mil each!
It's good money because dragonstones are 50k each, and 26 a load is only 1.3m to buy and when u sell u get 130m back!
