Astral Tournament
Astral Tournament is a turn-based magic duel game where your mage confronts the other mages to win the tournament. The aim of every duel is to kill the opposite mage (reduce his hit points below zero) by summoning creatures to fight on your side or using direct damage spells.All creatures and spells pertain to the following magical elements: Air, Fire, Water, Earth and Death. You start a duel with 20 power points distributed among all elements by random. And you have random sets of spells in each element.

The number of available power points affects spell casting, e.g. if your fire power equals 5 you can cast level 5 (or less) fire spells. When you cast a spell of level X, the corresponding element power reduces by X, but every turn all your magic powers increase by 1.
Mages has 5 creature slots each. It means that you can summon only 5 creatures or less.
You cast a spell (for example, summoning one) and then your creatures attack. Turn is over. Your enemy cast a spell (for example, chain lighting) and then his creatures attack you. And so on.
Each creature has attack strength, number of hit points and special abilities (such as ability to increase power points of the possessor or make mass damage). Every time creature performs an attack, it reduces opponent’s hit points by number of its’ attack strength. The creature dies then its’ hit points drop to zero.
The game is shareware. You have to pay $14.95 to gain access to all the spells.
I gave it 4 eyes award. I think it lacks of game balance a bit and there are not so many spells. Yes, I want more! More!
Try it anyway. It may change your life in some magic way.
