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 Regenerate keyword heals damage from itself equal to the specified amount each round. This takes place immediately following the passing of the first player token during the Refresh Phase, and occurs before player actions.
When setting up "The Watcher in the Water," remove The Watcher in the Water and Doors of Durin from the en-counter deck, and set them aside, out of play. These cards are placed away from the playing area and do not interact with the game until instructed by the cards of the scenario.
Doors of Durin has the text, "Progress tokens that would be placed on Doors of Durin are instead placed on the current quest card." This means that Doors of Durin can never leave play as an explored location, and in order to collect its victory points players must fulfill the requirement on the card itself.
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.
