If an encounter card with the doomed keyword is revealed during the staging step of the quest phase or in setup, each player must raise his threat level by the specified value.
When an encounter card with the surge keyword is revealed during the staging step of the quest phase or in setup, reveal 1 additional card from the encounter deck. Resolve the surge keyword immediately after resolving any when revealed effects on the card.
An enemy with the Indestructible keyword cannot be destroyed by damage, even when it has damage on it equal to its hit points.
When a player reveals an encounter card with the Peril keyword, he must resolve the staging of that card on his own without conferring with the other players. The other players cannot take any actions or trigger any responses during the resolution of that card's staging.
To play normal mode, just follow the setup instructions on the quest card.
When you play normal mode (or easy mode of course) and if you're new to the game, you can also play the "Basic Game" defined in the core set rules:
Newer players or players who want a more basic experience can play and enjoy the game by not dealing shadow cards during the combat phase. This eliminates an element of surprise that could make the game too challenging for a beginner. Once players are comfortable with this experience, they can then add the shadow effects to make combat less predictable and more exciting.
