From the campaign:
Become a hero and take the fate of the realm in your hands! Spells of Doom can be played with 2 players, where each player controls his own hero, or with 4 players, where the players cooperate in two teams, where each side tries to capture magic shrines and damage their opponents. In each turn each hero can do as much actions as possible by using mana.
