The Fiery Warpath (FW) is truly an elegant design. Many different optimal paths exist, depending on what it is that a hunter is optimizing: points, gold, speed, types of loot and more, as well as the hunter's equipment, style of hunting and many other characteristics. You don't need to become a MouseHunt guru to do well in FW, but there are some essentials that, once internalized, will let you surf the waves repeatedly with growing confidence on each pass. My goal is to provide you with those essentials.
A new concept is introduced in the Fiery Warpath: momentum. In addition, the mechanisms of selective attraction and selective effectiveness, introduced in Zugzwang's Tower, are expanded upon. If you focus on the concepts rather than the mechanics at first, the mechanics will flow.
I assume that you have read (or at least skimmed) the rest of the walkthrough, especially the sections on waves and streaks before you read this guide. I start with an in-depth discussion of Crimson Commanders, Gargantuamice and Caravan Guards, mice which are critical to the implementation of momentum in FW. I then move on to explore the implications for strategies for each wave for various goals.
