Quick poison crafting: Do I understand it correctly?

I was hoping someone would double check me on this to see if I'm right. I want to make sure I am not overlooking anything.

One of my fellow players is playing an 11th-level alchemist with the new Master Alchemist feat from the APG.

As such, he has a +40 modifier to his Craft (alchemy) checks when making alchemical items, uses gold instead of silver for determining time calculations, and can make 7 doses at a time (at increased cost, but not increased time).

Now, let's choose a fairly cheap, but effective poison. Oil of taggit is cheap, can knock most anyone out with enough doses, and is rather ideal for out of combat poisonings (such as drugging a drink prior to a kidnapping attempt).

It has a craft DC of 15 and costs 90gp per dose.

So we raise the DC by 10 to speed up the crafting time (as per the craft skill) and do the math:

Taking a 10 on our craft check, we always get 50, which we then multiply by the craft DC, 25, to determine the progress in gold 50 x 25 = 1,250gp.

Since we create the item once this calculation equals the poison's cost in gold, and time is reduced proportionately for every such increment we go over the final cost, this means that in one week's time I can create...

1,250gp / 90 = 13.8 doses in one week

However, since I have Master Alchemist, I can create 7 doses at a time (for the alchemist's 24 intelligence), which means I've actually crafted 97.2 doses in just one week (13.8 x 7 = 97.2).

So I spend 2,910gp to create 97 doses of oil of taggit in a little under a week, enough to drug the local ruler and their entire court many times over.

The same character could make 7 doses of black lotus extract in as little as three weeks using the same methods.

Does it look like I am following the rules and mathematical formula properly?

EDIT: For the purposes of the above calculations, I am operating under the assumption that poisons are considered alchemical items.


Your math seems right from just glancing over it. I don't think it's TOO fast though, while the best poisons are good, they're still quite expensive, and poisoning the local ruler and his court might prove somewhat difficult since a simple cantrip can spoil your attempt easily.


Your calculations are right, but you need to figure out the cost in silver not gold.

Why should he? Crafting time is determined by GP value with this feat. PRD link

Silver Crusade

Holy crap I did not know about that feat and am so taking it asap.

EDIT: At 3rd level, alchemists get Swift Alchemy: At 3rd level, an alchemist can create alchemical items with astounding speed. It takes an alchemist half the normal amount of time to create alchemical items.

Does this mean that you could potentially get 194 does in a week if you had the cash?

Sovereign Court

It gets even better if you have 3 lvls in the prestige class Daggermark Poisoner from the new Paths of Prestige. You get an ability that lets you use the PP value if you have the Master Alchemist feat. Convert all those vials into inhaled poison and dump it through the chimney then bar the doors and windows... thats what the LG Paladin would do... I think?

Edit: And it lets you make a number of doses equal to twice your Int modifier as well.

Silver Crusade

Man, my alchemist is going to get so much hot, elven archer nookie with this feat.

"Yeah baby, I'll poison your arrows all night long."
