You are playing Nightmare mode.
Setup: Shuffle the 10 encounter cards with the trait into a separate 'Balrog deck.'
When Durin's Bane would be dealt a shadow card, deal it from the Balrog deck instead of the encounter deck. Shadow cards dealt from the Balrog deck are discarded into a separate Balrog discard pile.
At the beginning of each combat phase (or if the Balrog deck runs out of cards), shuffle the Balrog discard pile back into the Balrog deck.
Begin with the standard quest deck and encounter deck for Foundations of Stone scenario.
Remove the following cards, in the specified quantities, from the standard encounter deck:
3x Goblin Scout
2x Goblin Tunnels
3x Stray Goblin
3x The Mountains' Roots
3x Ranging Goblin
1x Fiery Sword
1x Many Thonged Whip
Then, shuffle the encounter cards in this Nightmare Deck into the remainder of the standard Shadow and Flame encounter deck.
Finally, flip this setup card over and place it next to the quest deck. Its effect remains active throughout the game, which is now ready to begin.
Play Tip: This scenario contains 10 treachery cards with the trait that have only a 'shadow' effect, and no 'when revealed' effect. These cards are never revealed from the encounter deck and are only ever dealt as shadow cards to Durin's Bane.
