| Granny shouldn't be playing Old, 62 year old grandmothers should be wearing fire resistant underwear. See to it that you have a high fire resistance wearing rings, amulets, books, armour or even weapons, which increase this value. Maximum here is 80%.
More important however is that grandmother has to be a very cool grandmother. Leave your party behind (either set them waiting or send them away) and fight the dragon on your own. Do not fight the other monsters. Just walk around them while waiting for the dragon to rest. The dragon's fire will harm them, too. When you managed to fire a shot try to reset the ballista into its center position. You then do not need to move it more than twice next time the dragon rests. This will give grandmother someting to do while the monsters are going after her. They are about as fast as 62 year old grandmothers.
If you do not know how to make your party wait see the options menu for controls. There somewhere you can assign a key to that command. Only [f]ollow and [g]o are assigned by default. Granddad does not know why the others have been left out and set them to [q] for wait and [x] for guard.
So, I hope this helps and if not ask again and report some of your progress.
