You are playing Nightmare mode.

All Troll enemies gain the text: "Cannot have attachments."

If the encounter deck is empty (at any time), shuffle the encounter discard pile back into the encounter deck.

Begin with the standard quest deck and encounter deck for the Journey Along the Anduin scenario found in the LOTR LCG core set.

Remove the following cards, in the specified quantities, from the standard encounter deck:

3x Evil Storm

2x Treacherous Fog

2x Banks of the Anduin

3x Dol Guldur Orcs

2x Enchanted Stream

2x Despair

3x Misty Mountain Goblins

2x Necromancer's Pass

Then, shuffle the encounter cards in this Nightmare Deck into the remainder of the standard Journey Along the Anduin encounter deck.

Finally, flip this setup card over and place it next to the quest deck. Its effects remain active throughout the game, which is now ready to begin.
