In Astral Tournament duel you fight the other mage (computer or other player) for control of magical plane using creatures and other spells.

The creatures and spells are of the following magical elements: Air, Fire, Water, Earth and Death.

Each mage has five more numbers - they show his power in the appropriate magic element.

These powers affect the spells the mage can cast and the power of the spells also. (e.g. if your Fire power is 5 you can cast fire spells or summon fire creatures with level 5 or less).

Each time you cast spell/summon creature with level X your appropriate element power reduces by X, and each turn all of your powers are increased by 1.

If the creature attacks player/other creature that player's/creature's life is reduced by the attack strength the attacking creature possesses.

The object of the duel is to defeat your opponent by reducing his life number from 50 to 0.
