With some careful manoeuvring, and more than a little luck, we destroy most of a caravan with an uncontrolled avalance, and get in to a position where a magic fog cloud prevents the enemy from immediately overwhelming us.
Of course, this relatively comfortable situation cannot last. Fed up with us defeating her minions as they are sent to us one-by-one, kung-fu style, a spell is wasted to remove the fog cloud. As the last wisps of ethereal water vapour fade away, a cry can be heard from behind the caravan. 'Attack! Everyone attack!'
'Careful lads, we may be dealing with a master tactician.'
