Corrupted Terrain
Obstacle, Altar of Despair
I - Rules
(see AOD, p. 7)
Corrupted terrain does not block line of sight or movement. However, each time a hero spends a point of fatigue when on a corrupted space, the overlord gains 1 threat. Worse, each time a hero loses a wound while on a corrupted space, the overlord gains 2 threat. If a hero is struck by an "instant death" effect like a crushing wall while on a corrupted space, the overlord receives 2 threat for each wound the hero had before being killed.
