Hypersmurf said:Yeah - many people tended to forget that even on a wide-open plain, a volumetric fireball tended to expand a quarter larger than its listed radius... since you generally cast it centred at ground level, so you get a hemisphere with the same volume as the theoretical sphere...

Also, don´t forget volume displaced by PCs, NPCs and dungeon dressing.
There was a KotDT strip about that: Brian burned the party with a fireball because he forgot to include the volume of the skeletons in the corridor.
