I've preloaded and updated the Hero edition (which I ordered over a year ago). At that time I wasn't aware there would be more than one edition of this wonderful game. So naturally I would like to upgrade to the Champion edition. Is there any way I can do this short of making a full purchase of the Champion edition itself?

The Royal edition upgrade is $45.00 on STEAM.  The Chanpion Upgrade is $15.00  I am not seeing an upgrade option on GoG but may need to inquire further.

That royal edition upgrade should take in account if you have the champion edition or not, which it doesn't. I kickstarted this for $65 and the upgrade is $45 which would put it at $110, which is $20 dollars more than buying the royal edition itself.

You can buy digital add-ons in the backer portal as well if you only want specific things from the Royal edition.

Thanks for the info guys. Only I did check the 'updates' tab on my Steam account but couldn't find anything there. Could somebody please tell me where the options to upgrade (on Steam) are located. Thanks in advance.

Hey Leematon, send me a PM and I'll hook you up with Champion edition for free... Because I'm awesome like that
