I’ve been watching the development of the Delving Deeper OD&D clone (DD) with interest since it was announced. I even have a copy of Brave Halfling’s boxed set, which is not being offered anymore, but the reference rule PDFs are free in any case.
I’ve recently joined a Delving Deeper play-by-post game and although not needed for the game itself, it made me think of a printable character sheet. There are a few referenced in the OD&D forums, but some of those are missing some essential bits of data (like alignment), and I wanted something digest-sized I could print double-sided. So I created one based on my Swords & Wizardry Whitebox character sheet. Here is the link to the resulting Delving Deeper character sheet.
