[QUOTE="Celebrim, post: 6931631, member: 4937"] Ok, just to make sure, I went and looked, and they all look a lot like I expected them to look - very small flashes of low temperature fire with no observable pressure wave and no damage effects beyond a foot or two from where the flour intersected the flame. Most of them were less dangerous than your average 1" mortar shell you can buy in any southern state around the 4th of July, and in several cases I saw people actually caught in the flash but not getting burned. Essentially, they made not thermobaric bombs, but very small flame throwers that would do damage quite similar to a D&D torch - maybe 1d3 fire damage with a chance of igniting the target - if you were exposed to them. This is hardly surprising, as fundamentally what they are doing is exactly what a fire breather does only they propel the inflammable substance and atomize it using their mouth. The only actual themobaric bombs I found on youtube made with flour used very much as I expected, a black powder bomb (or in one case, tannerite) as a dispersal agent, and even with 10lbs of flour only produced shock waves with damaging effects over about a 5'-10 radius. None of these involved more than a couple dice of damage in D&D terms, and carrying 10lbs of flour and a blackpowder grenade to produce those effects would probably be less effective than carrying a blackpowder grenade and a cutlass. And in no case did I see anyone enhancing an explosion with flour beyond what they could have achieved with just more weight of regular explosives. If you have a 11lb bomb and access to blackpowder, you'd be better off with 10lbs of blackpowder and 1lb of pottery than 1lb of blackpowder and 10lbs of flour. Sure, but skill or no skill, I doubt a player could explain the technique his skilled PC was using to produce this effect. Then really, there is absolutely nothing we can tell you that is of any use to you at all. As there are no official rules on this matter, any thing we tell you is house rules that have no bearing on what your DM rules, nor should they. In fact, merely in asking us instead of your DM, you are basically being - I'm sure quite innocently - a jerk. If you were to ever try to say to your DM, "Someone on EnWorld said you should do it this way...", based on this thread, I hope your DM straightens you up in a hurry. I have a lot of opinions about how a table should be run and I'm fully willing to share them with fellow DMs and try to convince them to see the sense in what I'm saying, but I for one never argue with my DMs over anything, and I sure don't want to encourage that behavior in anyone else.
