Description from the publisher:
This is an Upgrade Kit allowing an owner of the original Shadows of Brimstone Core Sets (2014)—City of the Ancients and Swamps of Death—to turn them into Revised Shadows of Brimstone Core Sets (CotA and SoD, released in 2020).
It includes a collection of the printed material from these new sets that have mechanical changes to gameplay. The Upgrade Kit includes over 110 game cards, a set of selected large Hero Character Sheets and Enemy Record Sheets, a set of selected Extra Large cards for the Core Set Frontier Town Locations, and a counter sheet of new tokens. All of this material contains changes that were made for the Revised Editions of the City of the Ancients Core Set and the Swamps of Death Core Set, and is meant for veteran players that want to get the minimum amount of revised material that is new or contains changes to gameplay.
Note that there are many other changes in the Revised Core Sets that are simple wording tweaks, typo corrections, Art adjustments, minor changes for clarity, and the inclusion of a Set Symbol on every game card to help sort your collection more easily. The contents of this printed material Upgrade Kit only include changes that are mechanical in nature (that could change gameplay) as well as new cards, or in some cases, additional copies of existing cards that may not have, themselves, changed.
This item was only available for a limited time in 2020 and has since sold out.
