Hello Mordheim enthusiasts! Our gaming group has updated our Tomb of Mordheim's Burning, and the latest is available at
https://sites.google.com/view/wyldhauntsmordheim/home/tomb-of-mordheims-burningToMB is a try-to-include-it-all and balance-all-the-things-together approach to Mordheim itself, put together in one set of rules so our gaming group doesn't have to constantly refer to various sources for changes and additions through the last 24 years.
You may want to try using this as your Mordheim rules basis - if so, please understand it will play similarly to base Mordheim with a much greater emphasis on campaign (taking inspiration from Jim Weaver's "The Warpstones Belong To Us" campaign and Border Town Burning).
You may want to use this for mining ideas, similar to what Broheim and Mordheimer offer.
Either approach is fine of course - we offer our ruleset as a resource only; no advocacy for "the one true way to play" (cuz there is none).
Happy Wyrdstone Hunting!
