Are you running the game for the first time so you
don't know what to do? First, you need some mana points.
To receive mana points, you should sacrifice cards. Use
the right mouse button to sacrifice any of your cards.
Each time you sacrifice a card your astral power and
mana increase by 1. At the beginning of each turn you
receive a certain amount of mana equal to your amount
of astral power. You can sacrifice only 1 card per turn.
