There's a rich interaction between the elements that begs for experimentation. Every element has delightful interactions (e.g blood, fire, poison, water, steam, lightning, frost, oil, poison mist, ...) For instance, you could cast rain on a battlefield, poison the water and then set it on fire. Once the inferno has run the course you can put it out with a gentle rain, and then freeze your enemies solid with frost. Combat is a joy for the devious. :) The world itself is compelling and beautiful. You get sucked into quests and exploration -- the depth draws you in. Best RPG of all time -- definitely worth a purchase!
