Oh, the Roc wasn't carrying us off. This was the old style AD&D Roc who could carry off a small elephant, not the oversized eagle with a superiority complex of later editions. Mere humans were simply beneath it's consideration.

It was actually swooping down on the caravan we were with to grab a few banthar (guess where they came rom) pulling the wagon when the paralysis wand was successfully used. So instead of the loss of one wagon and team (although the people would have likely survived and the goods recoverable), it took out about six wagons and a few people when it failed to pull out of it's stoop.

After digging out the remains of the caravan (and the quite angry survivors) from under the carcass of the roc, we stineshaped a plinth with the inscribed warning "Danger: Falling Rocs" (because it was that sort of campaign).
