Jack the 7-Year Old | Monster for Dungeons & Dragons Fifth Edition (Happy Birthday, Jack!)

Tomorrow is the infamous DM Jack’s 7th birthday! Woohoo! Hard to believe that little peanut that appeared way back in 2011 is now a crazy, flippin’, reading’, joke-telling machine.

To celebrate Jack’s birthday, I thought I might make a monster out of him. After all, he’s my monster. #mushydadstuff

Oh, and he’s totally a monk/wizard. Deal with it.
