Ryan Ashmore and Jason Cotterell made this badass critical hits generator for WFRP, 2nd edition. It uses the expanded critical hits tables by Drs. Chuck Morrison and Josef Tham, which can be found over at Winds of Chaos. This particular version of the generator has our "Swords Against Satan" campaign as a header (WFRP, but set in the "real" world of the early 1600s), but otherwise all the references are to the Warhammer world. If you're like me, and derive entirely too much pleasure from these sorts of things, check it out!
