You convert material of one sort into a product that is of the same material. Creatures or magic items cannot be created or transmuted by the fabricate spell. The quality of items made by this spell is commensurate with the quality of material used as the basis for the new fabrication. If you work with a mineral, the target is reduced to 1 cubic foot per level instead of 10 cubic feet.
You must make an appropriate Craft check to fabricate articles requiring a high degree of craftsmanship.
Casting requires 1 round per 10 cubic feet [ 270 dmdM3] (or 1 cubic foot [ 27 dmdM3] ) of material to be affected by the spell.
Material Component
The original material, which costs the same amount as the raw materials required to craft the item to be created.
Craft (Int)
Like Knowledge, Perform, and Profession, Craft is actually a number of separate skills. You could have several Craft skills, each with its own ranks, each purchased as a separate skill. (...)
Check
The basic function of the Craft skill, however, is to allow you to make an item of the appropriate type. The DC depends on the complexity of the item to be created. The DC, your check results, and the price of the item determine how long it takes to make a particular item . The item’s finished price also determines the cost of raw materials.
(...)
Pay one-third of the item’s price for the cost of raw materials.

As u can already immagine the idea is trow severl hundreds of d6 acid damage on target. without saves, spell resistance or Attack check.
An acid flask weighs 0,5kg by player's handbook, omitting flask's weight and assuming that acid weighs as water 1 acid dose is 0,5Lt and measures 0,5 dM
3So, 1 Acid dose = = 0,5 dM
3 = 1d6 damage, and 1,5Mt cube (basic unit for dnd) has 3,375 M
3 volume that equals 3375 dM
3, so we don't have any space restriction to make fall a floating acid cube (due it's trasmutation and not cojuration) on the head of our enemies.
Fabricates, produces up to dmdM
3 /Level /Round , so we don't have also any quantity restriction (at least) for production of our mega acid splash.
The problem is having so much raw materials as material component of the spell.
"craft" skill says that raw material price for any craftable item is 1/3 of his price, so for our acid flask amounts at 3,33gp > 3gp .... giving you a spell that deals 1d6 damage every 3 gp invested.. maxout > 270d6 on 810 gp? INSANE!!
But a DM can say that the material to be transmuted has to be already in place when trasmuted (also if the spell description don't say so)..Then we need a floating mass of herbs over the head of op. before blast... or not?
Maybe crafting item rules can help us. The target will be always an area of 270dm3/lv ... full of air, 'cose material component isn't needed for spell cast from item.
Death from AboveSpell Trigger - Fabricate SL 5 CL 9 - 5x9x750 = 33750gp + Material component price: (3mo x 30[it's enough?])x50 = 4500gp > 38250gp for 50 30d6 acid charges No save - No SR - No Attack roll.. and bypasses Antimagic fields...Core only build ...Orb Spells? outdated.
... Same thing it's doable with poisons ... stick in some dose of Dragon Bile [Dragon bile Contact DC 26 3d6 Str 1,500 gp], more expensive but fun!
