Yes this is old but is has been a year and some people might have forgot or they might not even know...or even worst they might have fixed it so I'll have to test it in about 20 mins.
But this is how to get 40 Torches fast and free.
1. Get a friend and let him join your group.
2. Start throwing them on yourself while your friend stands in you ( like hugging/stacking )
3. Your friends will also receive the falling torches.
4. Now both start throwing em on yourself while hugging/stacking
Just remember you have to have done the torch quest(Witch I hope we don't have to redo this year)
