We have just finished a couple of games of the Watcher in the Water quest. During play we quickly got some of our heroes involved with some tent6acle attachments which rendered them unable to attack and defend and from there it seemed that their only job for the remainder of the game was to quest. However, when a Black Uruks (www.cardgamedb.com/index.php/lotr/lord-of-the-rings-card-spoiler/_/khazad-dum/black-uruks-kd) was revealed from the encounter deck we thought "great, that is our salvation". Because the Black Uruks does remove a chosen attachment from a questing hero - thus we removed the tentacle attachment from one of the heroes as this is an attachment just as any other attachment.
Or so we thought. However, what do you reckon? Is this a correct assumption and if not, why not?
