The magic system in Heroes V [Discussion]

Yeah, well, he did this: I had a few Druids left, and I kept attacking, attacking, attacking... But he didn't attack me. He just kept casting that minefield spell =) I didn't really want to switch to a new hero – I wanted to see what would happen)) It turned into an absolute mess, of course. But in a real battle, you obviously need to think 150 times before casting a fire trap. Especially when there's an alternative, like summoning a phoenix)) Overall, it's a useful spell, actually. If you ignore all the surveillance and cursed mark spells, tell me, what spell can make the enemy walk to their own doom during their own turn?
