If this was posted else where I apologize.

I am new DM and I need info on poisons. Mainly how long and how often can you make them. I think it is a week per dose? Anything else I should know about poisons? As a player I never used poisons so don't expect me to know anything about them.


Poisons use the standard crafting rules, where the times were based off what is reasonable for the gear in the equipment section. Poisons are not priced based off of that, but based off of a magic item equivalents. Because of this, their crafting times are prety absurd.

Formula: craft check * DC = # of silver pieces you produce per week. Subtract that from the final value. The DC is equal to the save DC of the poison.

This means that for a DC20 poison, if you just barely make the roll, you will produce 40 gp of poison per week for 1 dose. For a DC 12 poison, like Bloodroot, the same person would be producing 24 gp, so 5 weeks. This seems to put most poisons in the 10 week to produce range if you can just barely make it.

I recomend you use some houserule.

Thank you very much kind Caineach. Might you or anyone else have some existing house rules on poison crafting?


Check out this thread. I don't remember everything there, but it was talked about quite a bit.

Sovereign Court

You can always up the DC by 10 voluntarily to speed things up. Masterwork Alchemist lab is another +2, and Aid Another ("Igor, get over here!") can add +2 or more.

The Exchange

I was toying around with the idea of using some variant of craft points from the 3.5 Unearthed Arcana, in which you get so many points that can be used to instantly finish craft items (be they magical or mundane). It reduces the amount of time to just one day, but it does not allow you to do this infinitely.

That, or I was just going to take the crafting mundane items down to a check per day instead of by the week, with no division. It always seemed rather absurd to me that mundane items were harder to make (or at least took longer) than magic items of the same price. I know it's handwaved (Magic!), but it bothers me. This may also be because I plan on playing an alchemist soon and even with absurd bonuses it will still take me a long time per dose of poison, when they let me apply it as a swift action (so they assume that I will be using a lot of poison). Sticky poison can help, I guess, but I doesn't help in Ranged at all.

EDIT: Actually, you can just use the Complete Adventurer rules for poison making. You needed to equal the amount in GP, not SP, so it speeds the process up by a factor of 10. Also, if you have ready access to a supply of the raw stuff you need (like the animal that produces it) then the raw materials are only 1/6 of the base price.

I would suggest you use the crafting rules as written, with the following caveat:

PCs can purchase more refined incredients to speed the process along, though adding some danger of authorities noticing the purchases.

  • Purchase up to 80% of the cost of a poison. The remaining price is then the base crafting cost (1/3 of which must be spent to craft). For instance, if a dose of poison cost 150 gp, the PC could spend 120 gp on refined materials, leaving a base cost of 30 gp.

  • Per crafting rules they spend 10gp more, and begin crafting. If the DC was 15, and the player rolls a 20 on their check, they craft 300sp, or the entire remaining 30gp cost in 1 week.

  • You could also allow "harvested" ingredients (venom from a slain snake for instance) to count has XX% refined ingredients for Y doses. E.g. a successful DC 20 survival check could draw out raw venom, providing 50% refined ingredients for up to 3 doses.

    Though that raw venom has a computable cost, I would suggest that is rather difficult to sell (both illegal, and incomplete).

  • Scarab Sages

    I have this page which allows you to see how various poisons compare and also allows you to determine how long a poison takes to create, on average, by a crafter with a given Craft modifier.

    It uses rules mostly from various 3.5 sources that I found on the web.

    I believe jreyst may have copied this javascript-based page to d20pfsrd.org; it hasn't changed in a long time (that I can recall) so the one there is likely the same data.

    I believe that the Advanced Player's Guide (which features the alchemist as a poison-friendly class) will have a few new poison crafting options as well that makes crafting them a bit less onerous than simply using the Craft (alchemy) skill.

    This makes my alchemist very happy! I am getting more and more excited for the final version of this book, August cannot come soon enough.

    Can we get makeshift trap crafting rules too? The ones in the book work fine for something crafted into a keep, but are terrible for the ranger who wants to trap a bear (or Kobold).
