This is the Lair of Lith application site, where you can generate cards as well as save them if you create an account.
Currently we can generate character cards, as well as implementing the official algorithms so that you can interactively balance your characters.
Note: We support rendering portraits but do not support uploading them. Thus you can always choose a portrait to go with a card when you generate it, even if you don't own the card---you won't be changing the underlying card data itself.
Any feedback, bug reports, and feature requests can be made to this BGG Thread.
