Yes, the old fireball states that it CAN set objects on fire, but as ALWAYS, this was subject to DM fiat, even in AD&D, and I might add ESPECIALLY in AD&D. DMs in AD&D are by no means obligated to have things catch on fire, nothing has changed in that regard. The game still occasionally suffers from bad DM judgment, just like it always has. It is something that we as gamers must occasionally deal with."Dungeon Master, why did you tell us our magical Fireball didn't set the orc's stockade on fire because the Fireball spell only affects enemies, but now when we cast it in a confined space, you have it ignite everything around us, choking and killing us?"
In AD&D, this question doesn't come up because the Fireball spell explicitly states that it can set non-living matter on fire (subject to item saving throws). Famously, Steading of the Hill Giant Chief described the giant's wooden hall as too damp to able to set on fire easily (though still possible) to prevent this tactic.
Do I now have to spend another 5 pages of back and forth explaining why this is so? I think it would be easier if you were to just review the thread. It's already been covered.
