The magic system in Heroes V [Discussion]

Oh, the fire trap is truly awesome!!! I remember playing with a friend against a Djinn, a Dryad, and someone else, all with mines. He kept placing these mines every turn, and in the end, he mined the ENTIRE field 8) I started playing as Haven, and when my Rakshasas went on the attack, they died immediately, after 3 steps, because they hit 12 mines in a row. The Djinns also died quickly; 12 of them were destroyed at once by 4 mines. Only the Golems survived. That's what I call a powerful spell, this fire trap, it's just really cool 8)
