Teleportation will solve the economic problems; by selling to the entire world instead of just the local pawnshop, you can possibly find a market. And then spend your money to set up lots of local branch offices, with people capable of casting Sending or whatever to keep you informed of how business is going and what local demands are. Use this to track warfare and sell your weapons wherever they are needed. You probably won't be able to sell the maximum output of a level 20 wizard, but you'll make a very, very good profit, not to mention a lot of friends in high places if you sell at a bit below normal price. This assumes you don't flood the market or somebody casts dispel magic on the daggers.

These would be blade blanks not daggers, as daggers have wooden handles. Requiring more work than this accounts for and material cost. So you could fabricate the metal into 1lb ingots and sell those. If your DM is down with this level of shenaniganary, you might even get more for this by selling to places that otherwise can not easily obtain large quantities of metal.
Bitching about how "you shouldn't allow that" or "but that won't work in real life" goes here.  This includes "nuh-uh! yuh-huh!" counterarguments.

Regardless of any other imaginable or factual details regarding spells such as these it should be clear to any DM that in a world where blacksmithing (this may not always be the case, so it's probably better to say a world or worlds where mundane weapons are made without spells like this) your character would not be the first to think of doing something as mind numbingly obvious as this. In other words, if this was possible then why would anyone bother to become a blacksmith?
:: Any self respecting wizard would smack his head at the thought process behind all this, and just cast a first level Charm Person on whoever he wanted and have them give him all their money, assuming he cared about riches.
Also, creating a huge supply of iron out of nothing would add weight to the planet and can potentially do all sorts of crazy things, such as knocking it out of orbit, slowing it down, etc.

This article or section covers stupidly cheesy and/or broken crunch that gives powergamers and munchkins a serious hard-on at the expense of everyone else. It is extremely likely to cause Rage in whoever goes against it. So don’t use it, you dick.

Another exploit for Dungeons & Dragons 3rd Edition

Step by step guide[edit]

Prerequisites[edit]

Level 11 (minimum, will only net 3,000,000) Wizard, with max ranks in Weaponsmithing and the spells Wall of Iron and Fabricate.

Method[edit]

1. Cast Wall of Iron, creating a wall 55ft*5ft*2in=45.83cu ft of iron. This step costs 50gp in material components.

2. Cast Fabricate, converting 11 cu ft per cast into masterwork daggers. With 14 ranks in Craft (Weaponsmithing) and a wizard's crazy Int, you can't fail. Repeat until only 1-2 cu ft of iron remains. (4 casts). This consumes your 5th-level slots for the day, and takes 4 and a half minutes. The density of iron is 491lbs/cu ft. Thus 44 cu ft of iron weighs 21604 lbs. A dagger weighs 1 lb. Thus we create 21604 masterwork daggers, which sell for 151 gp each. That's 3,262,204 gp. Over 3 million gp. At level 11.

3. ????

4. Profit!

5. The spell description reads "You convert material of one sort into a product that is of the same material." therefore should any DM give you grief about singularity, connect each dagger by a thin thread of metal that can easily by clipped or removed after creation, thus giving you the countless daggers you were looking for. Folding the line of daggers may help conserve space for the plethora to-be.

Additional details[edit]

Teleportation will solve the economic problems; by selling to the entire world instead of just the local pawnshop, you can possibly find a market. And then spend your money to set up lots of local branch offices, with people capable of casting Sending or whatever to keep you informed of how business is going and what local demands are. Use this to track warfare and sell your weapons wherever they are needed. You probably won't be able to sell the maximum output of a level 20 wizard, but you'll make a very, very good profit, not to mention a lot of friends in high places if you sell at a bit below normal price. Until you flood the market, anyway.

Upgrades[edit]

20th level wizard, without using any slots above 6th level.

  • Volume of Iron = 5*5*20*(5/12)=208.33cu ft.
  • Castings of Fabricate = 10 (use 6th level slots to fill as required)
  • Fabricate time = 20 minutes per day
  • Mass of Iron Fabricated = 200*491=98200 lbs.
  • Number of Mwk Daggers = 98200
  • Payout = 98200*151=14,828,200 gp
  • Profit = 14,827,700 gp. Per day.

No Fun Allowed[edit]

These would be blade blanks not daggers, as daggers have wooden handles. Requiring more work than this accounts for and material cost. So you could fabricate the metal into 1lb ingots and sell those. If your DM is down with this level of shenaniganary, you might even get more for this by selling to places that otherwise can not easily obtain large quantities of metal.

Bitching about how "you shouldn't allow that" or "but that won't work in real life" goes here. This includes "nuh-uh! yuh-huh!" counterarguments.

"If your DM (assuming he wasn't sensible enough to put a stop to this before it begins) happens to fumble upon a Wall Street Magazine article in his basement toilet, he will recognize the law of supply and demand, which states that while the demand for said mwk daggers are roughly unchanged, the supply just sky-rocketed, making said daggers essentially worthless. Congrats."
"Infinite Multiverse == Infinite Demand. Suck on that, Malthus!"
"Infinite Multiverse == Infinite Supply by the same logic."
"Infinite Supply + Infinite Demand means the price is infinitely stable since no matter how many daggers you make it won't make a dent on infinity."
You need to understand how infinity(s) work. There are actually many different sizes of infinity. For instance by definition the set of natural numbers is infinite. The set of rational numbers is however infinite and also infinitely larger then the set of natural numbers. So the # of natural numbers divided by the # of rational numbers is zero even though both are infinitely large, and the inverse of that quasi-exotic fraction is infinity. There are an infinite number of larger and smaller infinities beyond that as well, for instance there are infinite number of irrational numbers between any two rational numbers so the number of irrational numbers is a much bigger infinity then even the infinitely large set of rational numbers, which is already infinitely larger then the set of natural numbers, which too is infinite.
Now for what this has to do with the economics of trying to sell infinite daggers in an infinite multiverse. In an infinite multiverse, infinite someones have already come up with this scheme and tried, using the money produced by it, to scale it up infinitely across the infinite multiverse with infinite time before you arrived. This infinite time for infinite scale-up across infinite universes should be a much larger infinity then the infinite number of universes. Thus the cost of daggers in the infinite multiverse should have gone to the tiniest fraction above zero already, with the infrastructure necessary to bring it to zero anywhere at a moments notice to cut in on new upstarts trying to get into the game already managed by the (infinitely) old rackets. Thus, if you are currently playing in a universe where daggers aren't already all-but-free there is only one possible explanation: the gods (and/or whatever else governs and makes rules for the universe you are in) thought the infinite dagger rackets were dumb and struck a deal with them: these rackets would stay the hell out of their universe (fine by them, there are infinite other universes where they can still run their business(es)) in trade for keeping any n00bs from starting up this BS from scratch in the universe or turning said n00bs over to these infinite multiverse-wide dagger making mafia. Thus, the second you start up this BS practice in a universe where daggers are not already all-but-free, the gods (or whatever) governing your universe have to make good on their deal to the infinite dagger rackets of the infinite multiverse and turn you over to them. These rackets meanwhile have had infinite time and resources to prepare for you, as well as the infinite number of other infinitely late upstarts who think they are so clever and new but are actually infinitely behind the curve. As such, you are in big trouble. Trouble that has command over literally anything that can be bought for any sum of money across all the infinite multiverse to deal with and make an example of you that will be infinitely memorable for all times and places of infinity. You would have been better off if you had just done something safer like merely mortally offended the entirety of the pantheon in your own universe.
First, there are an equal number of natural numbers and rational numbers. Second, any individual person pulling this trick would only be able to create finitely-many daggers and sell them to finitely-many worlds. Thirdly, assuming time stretches infinitely backwards across the multiverse, it is just as probable that you will be able to pull off the trick as it was for any other previous individual. Fourthly, there would be no reason to set up an entire racket for this trick (only so-much wealth is needed before there's nothing more to spend it on), and doing so would just make it work worse: the more gold you bring into a universe, the less valuable that gold will be. At a certain point, you might as well just create an inter-dimensional shipping company.
It is always bemusing to see things regress to this childish level of one-upsmanship on a universal scale. The creation of Infinite Cartels that function as edgy police to "teach you a lesson" is stupid. Ignoring the theological rabbit hole about how these stupid pieces of shit can exist in the first place and still have the multiverse/universe be the same place that isn't a utopia of plenty as would logically follow from infinite creation, faffing about with infinities will quickly lose the interest of sane players who don't want to have fun with calculators, and instead draw ire for not just saying "No" to this shit.
TL;DR: "3D printing" infinite daggers will quickly reveal itself to be a very dangerous and loosing proposition in an infinite multiverse. So in a finite universe economics says dagger price goes to zero, and in an infinite multiverse logic says you end up worse then dead faster then you can imagine.71.126.226.110 20:51, 14 December 2017 (UTC)

Ignoring the fact of infinite universes not implying infinite time. Given infinite time the rate of decay (half-life or fixed time) would be proportional to the amount of daggers, thus given a finite amount of daggers produced in a given time, the total amount would also be limited, since at the equilibrium an equal amount of daggers would decay as new ones would be created. Regarding the notion that infinite multiverses would imply infinite daggers thus a price per dagger near null is also misguided since there are only a limited number of daggers per multiverses (see first argument) the average number per multiverse is stable and arbitrary (It can't be zero, since we know that these daggers exist, or infinite though.). Stable because of your argument and arbitrary because because each multiverse produces an arbitrary amount, thus the average is arbitrary. Since we know it can be arbitrary and has to be a fixed number at he start (given by the first item sold) it will remain at that price forever since its stable.
A small wrong detail is that the # of the rational infinity is the same as the # of natural infinity (since a bijection can be made between them), the real/irrational numbers are infinitely more infinite than the rational and natural numbers though, given Cantors diagonal argument. This is irrelevant for the example, though.
"1. Implying the DM's world is an Infinite Multiverse. 2. Even if it were, implying the PCs have unlimited access to it."
When the market for masterwork daggers is saturated, you move on to slightly less profitable objects like masterwork swords, chainmail, farming implements, dragon-shaped paperweight and so on. By the time the demand for iron goods of any kind has dropped too low to make a profit, you are well into fuck-you money.
"A masterwork dagger would have to be made from steel, not just iron, which requires a significant element of heating, carbon inclusions, and forging. The Fabrication spell wouldn't be able to produce the carbon necessary. You would require a Wall of Steel variant to make this work"
That said, you can still crash the iron market at will."
Masterwork does not imply better materials, only better craftsmanship."
The spell description reads, "You convert material of one sort into a product that is of the same material." This could be interpreted as meaning you can only create a single item with a single casting. However, as stated earlier, you could create 21604 masterwork daggers bound together into a single piece through a series of easily removed channels. The final object may not be "a masterwork dagger" but it would be "a masterwork collection of daggers joined by channels" and each dagger can be considered a masterwork fragment of the original work even after they are separated. Given the wizard's intelligence and smithing skill, these kind of engineering and planning challenges can be considered trivial.
A DM worth the name should be able to come up with scenarios either preventing this or making the player pay for their arrogance.
If it is allowed to happen, it should only happen once and will shift the world economy drastically. Other NPC wizards can be considered to be just as intelligent as the PC and will quickly figure out what's going on and want to cash in on this. The player may make some money, but will soon find the market saturated ahead of them. This would be followed by masterwork iron goods being commonplace and worth about as much as your common dagger had been.
If the DM wishes to suppress this before it happens, invent a group or groups of wizards who have already discovered or done this and are carefully controlling the market so as to avoid crashing it. They've already put things into motion to detect if some other wizard re-discovers the technique. Once the PC tries to cash in, they'll quickly find out about it and act as necessary to suppress the effort.
The spell description also reads," Material Component: The original material, which costs the same amount as the raw materials required to craft the item to be created." This means that you can't fabricate a number of daggers just because you have the same weight of material. Since they cost about 100 gp in raw materials, you must use 1000 pounds of your wall of iron to make each masterwork dagger. The remaining weight of course goes back into the void, where it came from.
Several million gp's worth of product in four and a half minutes is not the same as several million gp's worth of sales in four and a half minutes. No sentient shopkeeper is going to think they can move an entire store's worth of identical products that they likely already have three or four of sitting un-bought on the shelf; it may take less than five minutes to create the stock but it would take months to sell it. Unless you can make a name for yourself as an arms dealer supplying kings and warlords with armies' worth of equipment, you'd probably be better off just trying to sell the iron to craftsmen.
Nothing in the fabricate spell suggests that it allows smelting or metallurgy. Iron is a sufficient material for making daggers, but it isn't "state of the art" for even normal blades. Compared to the fine steel of a masterwork dagger, iron is softer, more easily broken or bent out of shape without returning to true, and does not hold as fine an edge. Using this method would not yield any number of masterwork daggers, but instead the indicated number of finely shaped daggers of a substandard material. They would be more valuable for the raw metal than as weapons, outside of any town with a crippling dagger shortage. With this method, you would burn all your 5th level slots to turn 21,604 pounds of iron into 21,604 pounds of iron in a different shape without improving at all on its value.
Just Fabricate the wall into 1 lb. iron ingots connected by small channels. According to the SRD 1 lb. of iron is 1sp. Not quite 15 million gp a day, but still enough to crash the market.
Price fixing is also an issue. The value of spellcasters is fixed per the hirelings section. A 6th-level spell cast by an 11th-level wizard with a 50gp material component costs 710 gold. Therefore, the value of any Wall of Iron is set at 710 (slightly more for a higher-level caster), meaning you cannot fabricate more than 710 gold worth of masterwork daggers from a single Wall of Iron as per the description of Fabricate.
Don't try this in Pathfinder either. D&D 3.75 added this wonderful line: 'Iron created by this spell is not suitable for use in the creation of other objects and cannot be sold.' It's magic, they don't have to explain it.
Well, aside from the new questions that the statement raises (Is a 1000-lb section of wall incapable of crushing a man, as that would be a type of use? Has the iron been made magically incapable of being sold? Does a forcefield spring up anytime someone tries to hand you money in exchange for a piece of it? If you hide a lump of the stuff in a bag of apples, then sell the bag and its contents, the bag won't move, a la an immovable rod?), you can still run a grift with fake shoddy daggers, or make a profit in trade instead of currency.
Maybe you get busted for trying to sell "Wizard Iron" which is basically worthless as iron.
The wall itself and everything made of it may disappear back to where it was conjured from after a set amount of time. Daggers going "Poof!" shortly after (or before) being sold aren't that good of a ware.
It could be very, very poor quality iron, something like 50% impurities, that's not worth the fuel needed to forge it into anything. It can theoretically be sold to anybody who needed 1000lbs of hard weight, but then they could just go grab a boulder that's lying around.
Because you need to be a level 20 wizard to pull this off, at which point you've got better things to do than selling 98200 lbs of iron.

Regardless of any other imaginable or factual details regarding spells such as these it should be clear to any DM that in a world where blacksmithing (this may not always be the case, so it's probably better to say a world or worlds where mundane weapons are made without spells like this) your character would not be the first to think of doing something as mind numbingly obvious as this. In other words, if this was possible then why would anyone bother to become a blacksmith?

Any self respecting wizard would smack his head at the thought process behind all this, and just cast a first level Charm Person on whoever he wanted and have them give him all their money, assuming he cared about riches.

Also, creating a huge supply of iron out of nothing would add weight to the planet and can potentially do all sorts of crazy things, such as knocking it out of orbit, slowing it down, etc.
