Re: OOC Thread
That's a good example of the fireball spell being mismanaged. Given that false treasure room was 20 x 20 room with let's say the standard 10 foot high ceiling it had a volume of 4000 cubic feet, and the 20 foot long hallway descending to the room had another 2000 cubic feet of volume, which gives a total volume of 6,000 cubic feet.
A fireball has a volume of 33,000 cubic feet and the wizard that threw the 1st fire ball, not only incinerated himself by the flashback as the expanding fireball filled the room and then extended way up the hallway, but the rest of the party as well. Kudos to you for getting away with it though.
The size of a fireball is also one of the factors that limits its usefulness.
If you're going to throw a fireball inside, the room has to be at least 60 x 60 with a 10 foot high ceiling, and you're standing in a corner. In most cases a fireball spell inside is TPK situation, a lightning bolt is a much better option, though that also has ricochet issue.
