Just beat it with my son, we added both wraith on our Victory display since we destroyed them both. Are they removed from campaign pool or we use them again on black gate opens and mount doom (one each) we will play on epic mode after?
Edited by NickpesQuestion on Tower of Cirith Ungol campaign mode
The Wraiths are not removed. They would be removed for mount doom if you were playing black gate by itself and destroyed them. But since youre doing epic mode, you have the joy of having them all the way through!
