Delay the Enemy
The Siege of Annúminas#9 (x1)
1E-F (-)
Setup: Set Lieutenant of Angmar , Battering Ram, Enemy Camp , Siege Tunnel, each copy of Host of Angmar , and each copy of Dúnedain of Annúminas aside, out of play. Each player searches the encounter deck for a different enemy and adds it to the staging area. One of these enemies must be Vanguard of Carn Dûm. Shuffle the encounter deck.

An army from Angmar marches on the Dúnedain city of Annúminas. Your friends need time to prepare the defense, so you ride out to meet the enemy.
Forced: At the beginning of the round (before the resource phase), place 1 resource here. Then, if there are 4 resources here, advance to stage 2.

Response: At the end of the round, remove 10 progress from this stage, then the players at each other stage reveal 1 fewer encounter card during their next quest phase (to a minimum of 0).

It's up to you to harry the Orcs and slow their approach to the city.
