I just played epic play twice with my friends. It seems that we discovered a game breaking combination: Knight with defend + stone armor. This combination is particularly difficult do deal with when the hero is Hugo the Glorious. (please see the following links/descriptions of the cards)
Hugo the Glorious:
Stone armor: I could not find this one so it is described below
2 black dice
movement seed reduced to 3
may not use fatigue to move
This makes him nearly invincible! Additionally it allows the other three members to just deal massive damage with out the need of a healer. I believe the access to two black dice is possibly game breaking when compared to the cost of other armors!
I would like some suggestions for how the overlord should deal with this hero. Basically with a hero like Hugo the penalties associated with this armor are minimal and I can not find a way to deal with it. I have tried removing his fatigue, using smaller monsters, and the infection deck. (One thing I have not tried is just trying to continually trap him so he can not move; but often times he does not want to move and can use Oath of Honor to get around these restrictions.) With this combo it is not possible to consistently deal enough damage to the other heros to knock anyone down. Not every quest is time dependent when you don't have to worry about taking damage and can tank all the attacks the overlord can send at you.
The only thing I can think of is that this armor should have two gray dice instead of two blacks. I would like to see what the community thinks about this item/combination!
