The Chaos Event deck (also called Evil Wizard deck) is a set of cards created to add some variety to our favourite dungeon crawler game and spice up your quests, solving annoying problems like a hero (usually the Barbarian) blocking a door and many other things.
Each card is different but players don’t need to study any additional rule because everything you need to know is written on the cards. The most common way to use this deck is the following: if the Evil Wizard player starts his turn with no monster to move (no miniatures placed on the board or unable to reach the Heroes or attacking them), he may roll one combat die. If a skull is rolled, he may draw one Chaos Event card. Remember, the card eventually drawn is for the Evil Wizard player’s eyes only and must be revealed to the Heroes only when it’s played. The text on the card explains when it can be used.
Only one card per turn can be played and its effect cannot be combined with other cards.
A card is discarded after it is used.
At the end of a Quest, all unused Chaos Event cards must be returned to the deck and shuffled.
