Oh hey, look at that: improvised damage list from dmg says crushed by a wall and wading through lava both do 10d10 damage 

So, with the ground covered in 500 pounds of burning oil dumped out from a bag of holding in a single turn, with a flask of alchemist fire inside to set it all on fire on impact, one might put this in the 6d10 points of fire damage category of improvised damage, and last for 2 rounds.

Thats 66 points of damage, on average.

Oh, man. And to think of all the stuff everyone was making up to say, with absolute certainty, that this wouldnt work at all or would only do 5 points dmg.

60 to 70 damage works for me

*Improvised damage is at the whims of the DM and only found in the DMG, player discretion advised

Thank you for your help, adventurer. But Im afraid we have no gold to reward your noble work

I cannot tell if your trying to make everyone mad or that your mad because we objected to what was clearly a faulty reading of the rules. I mean, if your dm allows it sure, but don’t say that it’s totally RAW or normal, especially when you're forced to use your dm's good graces.

"your mad because we objected to what was clearly a faulty reading of the rules."

Remember when you told me this:

"This doesn’t work at all, both  Iin theory and practically. A [magic items]Bag of Holding[/magic items] has a size of 2 feet square and is 4 feet deep on the inside, because of how a barrel works, you cannot contain a barrel inside a bag of holding unless it is especially small. "

 by "faulty" did you mean a slightly smaller barrel isnt on the equipment list therefore is impossible to exist? 

I know thousands of points of damage isnt realistic in the game. I assume any reasonable dm would figure out a reasonable amount of damage.  But weirdly, out of everyone who commented on this post, not one person said, a thousand is too high, but id let you roll 5d10 or 8d6 or something.

You apparently were absolutely certain it was an impossible idea, in part, because a bag of holdijg has a 2 foot opening, and you couldnt imagine a barrel existed that could possibly fit. You wrote an entire paragraph based on being unable to improvise a slightly smaller-than-standard barrel. I mean, the equipment list doesnt even give the diameter of a barrel, so im not sure how youre so certain that it wont fit while youbalso insist on only allowing rules as written.

Dnd is not a computer game. Theres a lot of stuff that players are going to want to do thats not on any rule book anywhere. And a complete and total inability to improvise in response to that, is not helping anyone.

 1. After checking, yea, the barrel would fit, a 40 gallon barrel (as seen in the basic rules) would be around 22 inches wide and be considered to be able to contain 151 litres, so it would indeed fit, my bad.

2. Just because you would allow it doesn’t mean others would, if your assuming the dm is agreeing, than it’s completely on their terms and should be placed in a homebrew forum instead, seeing as it’s closer to discussions of more flexible rules rather than Tips & Tactics. Which uses the closest to RAI or RAW rulings as possible due to there being massively differing interpretations per table.

3. You literally included a barrel for no reason, removing the barrel from the equation would have made it (slightly) more usable. If you didn’t want me to calculate the barrel, why include it in there? Additionally, the barrel is only a 1/3 of the argument, if you forgot this: “If multiple effects impose the same condition on you, each instance of the condition has its own duration, but the condition’s effects don’t get worse. Either you have a condition or you don’t. The Exhaustion condition is an exception; its effects get worse if you have the condition and receive it again.” - D&D Beyond Basic Rules

Although it focuses on conditions, it’s still related to how Oil actually works in the game. D&D is not a computer game, chess is also not a computer game, saying that a large branch a player found does 1d6 Bludgeoning is a good improvisation of rules, claiming that you can create an instant firebomb because more oil = more hot is not good improvisation, if you are suggesting this as a player, it’s just that, a suggestion. Maybe don’t misinform possible players who are just getting into the game, cheers 😊.

And always remember that whatever you do, the monsters can do too =)
