I seen a guide on Sythe that making unfinished potion can make a lot of money but which one shall I make? I have 30+ Herblore Level
It would be good to check out the ge database and compare the cost of the herb to the cost of the unfinished potion it makes. Water filled vials are 42gp ea atm so won't have much effect on the cost if you are doing the more expensive/high level herbs.
you have to find the right unf pots that have the greatest price gap between the herb and the unf pot, so it all depends on the market and prices of herbs ect.
Properly won't risk my money on unfinished potions Properly won't risk my money on unfinished potions
Just check the prices on the G.E. to see what is best. When I did it for maximum cash I got 70 herblore so I could do pretty much any herb for the best profit.
