Ok, so I was playing with the Spirit sphere of influence deck and the Passage through Mirkwood scenario. The final task was revealed that I had to defeat the Ungoliant's spawn. My threat was only 29 so I was able to get 4 damage on him using Dunhere's ability to attack enemies in the staging area. But once my threat was up to 32, the same as the enemy, after he engaged me, I am no longer able to defeat him since all of my heroes and units are only 2 power or less. I searched through the whole deck and there wasn't one card that would increase the power so it looks like I cannot win because the ungoliants spawn's defense was 2 shields.
Am I missing something?
