Fudging isn’t unique to DND, though I agree that people would be better off trying anything else.

The system is a means to an end. No system captures its tone perfectly through mechanics.

In chainmail, the war game dnd is historically based on, a hit point is a fraction of a hit dice, each HD represents one soldier, roughly, so 12hp being the average of 4hd isn’t too bad, no.

Did you understand the communication being made? Clearly so. Looks like I used adequate wording.

Getting high oxygen isn’t enough, you need propane purity and oxidizer purity (the not air inert gas and oxygen mix) or you get unburnt products. You also need perfect mixing, and essentially an adiabatic chamber. There is no combustion chamber on this earth outside of some absurd combustion lab that doesn’t have soot buildup.

Not things you’d find in a dusty standard ass DND dungeon. But please continue bending over backwards to justify why you couldn’t just day “you didn’t think anything of it”

Synonyms.

And sure, that’s another explanation agm could use, I wasn’t being comprehensive or I’d be here forever.

Take a lighter to a rock. Fires leave char. There are very few combustion systems with a pure enough burn to avoid it.

That’s not rules lawyering at all. If a player asks why they didn’t spot that the easy answer is they didn’t realize it was char.
