The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
A password locked PC PDF page where only the judges could get in should get around the pesky WotC license issue. The player could just Email the PDF to the DM and the judges at the same time.
I was unclear there. I was thinking of a P/W protected web page which contained links to the .PDFs.
There are .PDF products that allow for the creation of read protection and/or modification protection, but I suspect that none of the .PDF freewares support those more advanced features.
Also, Adobe Reader does not allow for the creation of .PDF files. One would need a write tool.
