I had great fun in the past playing Dungeons & Dragons, but our sessions always kept getting a bit out of hand.
I remember one adventure where we had to storm an impregnable castle of the main villain. Our dungeon master was a bit easy to influence, and then there was this overpowered spell, Polymorph, which allowed you to change a creature permanently into another creature.
We found a flock of sheep, and with polymorph, turned them all into flying Pegasi. We also had some Bags of Holding, a magical item which allowed for the storage of items of infinite weight.
So we stocked these bags with enormous boulders, loaded them on to the pegasi, and proceeded to arial bombard the castle. We thought it hilarious at the time. Thinking back, it probably wasn’t the best of epic stories 🙂
