Custome Sheet

So i found a fan made rule set that i want to run but i need to create a character sheet, the problem is that the sheet development page says to select custom as the template option, my problem the custome option just shows a persona sheet. Am I being dump or is there no custom option?

You only get the Custom Sheet option if you are a Pro subscriber. Plus, designing sheets is best done using the Custom Sheet Sandbox (which also needs a pro subscription). If you are making a sheet, the best bet is to find an existing sheet that looks as close to what you want as possible (and doesnt have By Roll20 after the name), copy that and make whatever tweaks to it you need. Making a new sheet from scratch can take dozens to hundreds of hours.
