Obstacle, Altar of Despair
I - Rules
(see AOD, p. 7)
Altars do not block movement or line of sight. Altars have effects that vary by quest, but the method to activate them is always the same:
To activate a good altar, a hero must stand on top of the altar, spend 2 movement points as a movement action, and spend 250 coins. The altar's effect then takes place as described in the quest.
To activate an evil altar, the overlord must move a monster on top of the altar and have the monster spend 2 movement points. The monster is then killed and the altar's effect takes place as described in the quest.
