Transmuting can make you decent gold in a matter of minutes each day. You don’t even need to be a transmute master (although that helps make more gold with it).
There are several transmutes you can do for profit, what you want to do is find out the one that makes you the most profit on your server.
Just input the cost of these items on your server in the format 2g50s = 2.5 and click Compute Profit. Then below it will calculate the profit for each transmute to help you decide which option is best for you. Default values are the average prices across servers.
