Mastering Iron Heroes introduces two important new concepts to your Iron Heroes game: zones (areas of the battlefield which have special effects or grant you extra tactical options) and villain classes (which allow you to create quickly versatile enemies for your game). "Borgnok’s Raid" is a short encounter designed to demonstrate these new game features in action. This web enhancement is intended for a group of four 1st-level Iron Heroes characters. Suitable characters should take only a few minutes to generate using the starting packages in Chapter Three of Iron Heroes. Feel free to fit this encounter by Adam Windsor (designer of the Iron Heroes official adventure Dark Harbor from Fiery Dragon Productions) into your home game, or use it as the start of a new Iron Heroes campaign. You don’t need Mastering Iron Heroes to use this web enhancement, but you will find its rules on zones and villain classes helpful as you run "Borgnok’s Raid."
