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.
An enemy with the toughness keyword reduces the amount of damage it takes by X each time it is assigned any amount of damage.
Tom and Kris are playing the scenario "Into Ithilien," and two copies of Southron Mercenaries are in play. Southron Mercenaries has the keyword archery X, where X is the number of players in the game. This gives a cumulative archery value of 4. At the beginning of the combat phase, the players decide to deal 2 damage to Kris' ally Gandalf, and 2 damage to Tom's hero Denethor.
While a card with the archery keyword is in play, players must deal damage to character cards in play equal to the specified archery value at the beginning of each combat phase. This damage can be dealt to characters under any player's control, and it can be divided among the players as they see fit. If there is disagreement as to where to assign archery damage, the first player makes the final decision. If multiple cards with the archery keyword are in play, the effects are cumulative. Remember that does not block archery damage.
When setting up The Uruk-hai, players are instructed to set the pursuit value to 10. This is done by taking an extra threat tracker and setting it next to the quest deck. That threat tracker is now the pursuit tracker, and it tracks the pursuit value. The pursuit value represents the Uruk-hai's progress as they race towards Isengard with their prisoners. As the pursuit value increases, so does the amount of progress that the players must place on the current quest in order to defeat that stage. At the end of the round, if the pursuit value is 30, then the Uruk-hai have reached Isengard and delivered their prisoners to Saruman. If this happens, the players have failed to rescue their companions and they lose the game.
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.
