Fabricate, the best core blast spell?

[7h39]

Reference:

Fabricate
Transmutation
Level:   Sor/Wiz 5
Components:   V, S, M
Casting Time:   See text
Range:   Close (25 ft. + 5 ft./2 levels)
Target:   Up to 10 cu. ft./level; see text
Duration:   Instantaneous
Saving Throw:   None
Spell Resistance:   No
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.

Table: Special Substances and Items
Goods   Cost   Weight
Acid (flask)   10 gp   1 lb (0,5 kg) .
Alchemist’s fire (flask)   20 gp   1 lb.
Antitoxin (vial)   50 gp   —
Everburning torch   110 gp   1 lb.
Holy water (flask)   25 gp   1 lb.
Smokestick   20 gp   ½ lb.
Sunrod   2 gp   1 lb.
Tanglefoot bag   50 gp   4 lb.
Thunderstone   30 gp   1 lb.
Tindertwig   1 gp   —

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 dM³

So, 1 Acid dose =  = 0,5 dM³ = 1d6 damage, and 1,5Mt cube (basic unit for dnd) has 3,375 M³ volume that equals 3375 dM³, 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 dmdM³ /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 Above
Spell 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!

At a glance, it stands to reason that you need the materials to fabricate/convert already in the space of the creature you want to affect. Like you said, floating mass of herbs. You can probably achieve this with a quickened Dimension Hop before standard action fabricate.

Despite all this, any sane DM should be capping this at 20d6 as an environmental hazard, after all, submerged in lava is 20d6 a round.

Don't creation spells need a solid surface to cast them on?

Don't creation spells need a solid surface to cast them on?

Yes but is trasmutation!However for the purpose of a cojuration (creation) effect, a solid surface like an human head/shoulders aren't viable?

20d6 seems fair... being 270 the max output
But for the items rules i don't need any material component if a i paid x50times in creation? or not?

In addition, some items cast or replicate spells with costly material components or with XP components. For these items, the market price equals the base price plus an extra price for the spell component costs. Each XP in the component costs adds 5 gp to the market price. The cost to create these items is the magic supplies cost and the base XP cost (both determined by the base price) plus the costs for the components. Descriptions of these items include an entry that gives the total cost of creating the item

there is some trick to reduce che casting time of minor creation and achieve the same result/ make 270 doses of black lotus poison on the face of the opponent?

[WarlockLord]

You use shadow conjuration for that, generally.

[RedWarlock]

You convert material of one sort into a product that is of the same material.

Wouldn't that need to be an acid to start with, then? And it only reshapes it, it doesn't increase the amount of material.

[JaronK]

The best core blast spell of this type is Major Creation, but you need it as a spell like ability to suddenly dump gallons and gallons of Black Lotus Poison on someone.

Or maybe a use-activated object.

Unless stated otherwise (and as stated in the Dungeon Master's Guide), activating a use-activated item is either a standard action or not an action at all and does not provoke attacks of opportunity, unless the use involves performing an action that provokes an attack of opportunity in itself. For example, a magic bow requires you to make a ranged attack, so you provoke an attack of opportunity when you make the ranged attack.

If the use of the item takes time before a magical effect occurs, then use activation is a standard action. If the item's activation is subsumed in its use and takes no extra time, use activation is not an action at all.

"If the use of the item takes time before a magical effect occurs, then use activation is a standard action" : so standard action to activate a Minor creation  for (as suggested) Black lotus extract Contact DC 20 3d6 Con/3d6 Con

Standing @Physical Description of potions  and minor creation description, the spell creates 957,51 ounces of potion (1 dose: 1 ounce) / caster level

Standing on my assumpion on acid flask

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 dM3

(sorry for using decimal) spell creates 13.5 doses/caster level

In any case the quantity is absud.

Now, does the surface of head, shoulders, arms, legs, torso and whaterver qualificate as "open location on a surface capable of supporting it." (rules of conjuration) ?

I think the only limitation it could have is 1min recharge time between launches (the item pre-charge the spell)

[Bozwevial]

As a side note, submersion in acid deals 10d6 a round, not the 20d6 of lava.
