Really depends on your lvls mate.
Puropuro pro still works best.
Although i wouldnt use it more then a few hours since it has a high banrate.
You might consider autotanner as a lvl3 method but honestly, it can get you a stable 350k an hour. Still 100k more then sorcgarden.
Only problem is, the hides sometimes take time to buy, and theyre quite expensive,
So in order to continuesly bot it, without having to buy a new set of supplies everytime, its adviced to have atleast 20-50m.
Autodragonscale with 70agility and bob support =
400+k per hour, used to be 500+k but the price of dragonscales lowered.
This bot has a very low banrate,
Ive farmed 100m with it,
by 12/7 on my second main.
For real money, the best way is probably merching.
The more cash, the more you merch.
