Cast a spell at them.
From Create Your Own Story
You cast a fireball into the creature's midst. They all fly in different directions, and it was a very good example of spell use! A few fly out the windows, where they fall over 50 feet and die. Others fly out the door, and some hit their heads on the furnature. This gives you the time you need to kill them all! You have won against evil and become a king in this castle.
THE END!
