This add on includes 5 fully playable Heroes, each an alternate gender variant of their respective class from the core game:
5 Soul Gems
5 Deluxe Hero Sheets
5 decks of Hero Power Cards
Each Hero has the same class as one matching Hero included in the Ancient Chronicles Core Set. Using this Alternate Hero pack you can play with two Heroes of the same class (or with the two different versions of the Hero) in the same game.
You can customize each Hero using a different "Traits" card (included with each Hero in Ancient Chronicles) or a different "Background" card (from the appropriate deck).
