Attached encounter card gets +2 
and is immune to player card effects.
Action: Exhaust The Serpent's Garb and raise your threat by 1 to give a Harad enemy in the staging area -2 until the end of the phase.
While The Serpent's Redoubt is in the staging area, it gains:"Forced: After a player plays an ally from his hand, either remove 1 progress from the main quest, or exhaust that ally."
Travel: The first player searches the encounter deck and discard pile for an enemy and puts it into play engaged with him. Shuffle the encounter deck.
While Banner of the Serpent is attached to an encounter card, each Harad enemy gets +1 
Action: Exhaust Banner of the Serpent and raise your threat by 1 to give each Harad enemy engaged with you -1 until the end of the phase.
Your plan is working. You've nearly succeeded in capturing the Southron caravan, but The Black Serpent himself holds the last token you need to infiltrate Cirith Gurat. He will not surrender it willingly...
When Revealed: Randomly select 1 set aside Harad objective and attach it to The Black Serpent. Shuffle the encounter discard pile into the encounter deck and reveal 1 encounter card per player.
If a Harad objective is not attached, the first player claims it and attaches it to a hero he controls.
While there are at least 6 progress tokens on this stage, the Black Serpent loses the text: "Cannot leave the staging area or take damage."
This stage cannot be defeated unless each Harad objective in play is attached to a hero. If the players defeat this stage, they win the game.
