They have 3 objectives: - 3+3 fish - 5 fire elementals - 40 pixies Pixies are the most dangerous unit here, so they will likely target them (although I might be wrong, maybe 3+3 fish are more dangerous?). I don't have a save file; I just formatted my hard drive and haven't even installed Heroes yet (so I can't test it). Create a scenario based on the description above. If we swap the fire elementals and pixies, we'll get an increase in damage from the fire elementals (up to a maximum of 36), while the pixies deal something like 38-76 damage. So, even with the extra damage, it won't be possible to finish off the remaining unit in a single round.
