Two Worlds Tuesday #4

IGN has published their fourth Two Worlds Tuesday feature, this time providing us with an overview of the game's magic system. It sounds somewhat unique, anyway:
Every spell has a card associated with it and just like any other piece of equipment, you'll have to buy, find or steal them to put them in your inventory. Also like any other equipment in the game, you can stack cards that are the same to create more powerful versions of that spell. In addition, you'll also occasionally find booster cards that have such effects as reducing the mana required to cast a spell or increasing a spell's duration. Booster cards can be stacked as well.

There's no limit to how many spell or booster cards you can stack on top of one another, but there is one thing that will keep you from going too crazy. Stack too many cards together and you'll create a spell that costs you more mana than you have to cast!
