Tifone - by making the spell last only 9 turns, it is just one of the many spells that can be quickly cast to do some damage by a retreating caster. In fact, there are others that would work better. By putting a time limit on it, the 75 turn limit is never reached, and the other force is not automatically dissolved by game mechanics.

Chris - there is really no way around the concept that this is a glaring bug. Casting a BE and then leaving wouldn't be nearly as big a deal, because the battle would end. However, it was never intended that the constant autosummoned units from MoD would keep the fight going indefinitely. ie- you can NEVER make them stop coming, so you cannot win the fight. All Mindless units are forfeit, and if this tactic is used defensively, I'm pretty sure that defender keeps their units even if they're forced to route, but the attacker loses ALL units remaining on the field. Now you don't even have to kill them in the defensive use, you're just trapping them there to die uselessly.
