Alchemists can make WORT's to make money.
For example, here is what T5 WORT's sell back for:
Old Crude (1x pristine combine) - 16s15c
Old Shaped (2x pristine combine) - 8s8c
Old Regular (3x pristine combine) - 5s38c
Old Pristine (4x pristine combine) - 4s4c
When you less out the costs for fuels and liquid (which are repaid) you profit the following:
T1 - 11c
T2 - 41c
T3 - 1s 65c
T4 - 3s 30c
T5 - 6s 59c
If you don't harvest your own raws then make sure you don't pay more then the above to make a profit. Currently on my server I can find T5 raws for less than 2s.
To maximize your profits vs. time you should make the Old Crude (1x pristine).
With a good macro program and a T5 alchemist, I am making around 15g an hour. Not too bad for being AFK during the entire thing
Warning all stack now, and will sell back for the lowest price. So if you stack a 1x on a 4x you will only get 4s4c. Therefore, you will be loosing money.
