When Revealed: The opposing team searches the top 5 cards of the encounter deck for a card with cost 2 or less (3 or less if there are two or more players), sets it aside, and shuffles the encounter deck. Reveal the set aside card. Its 'when revealed' effects cannot be canceled.

The dark form of Dol Guldur rises up ahead. The servants of the Enemy patrol the surrounding woods. You must take great care to gather what information you can and return with news to Rhosgobel before it's too late.
When Revealed: Shuffle the encounter discard pile into the encounter deck. Each player discards from the top of the encounter deck until he discards an enemy, adds that enemy to the staging area, and attached a hero he controls to it as a guarded objective (discard all tokens from the chosen hero).

If there is an unguarded hero in the staging area, return it to its owner's control, exhausted. This stage cannot be defeated while there is a guarded objective in play. If the players defeat this stage, they win the game.
