These rules offer the “Extract Venom” exploration activity which is used to allow Players to extract the venom from recently slain creatures, when such rules are not available within the creature’s description.

EXTRACT VENOM

 CONCENTRATE    EXPLORATION    MANIPULATE  
This activity has two steps, with the second step being optional.
Requirements

• To Extract: Trained in the Survival skill.
• To Stabilize: Alchemical Crafting feat
• Tools to Extract: A Carver’s Kit (a toolkit that consists of scrapers, a mincing blade, bone saws, and several fine knives. Costs 4 gp).
• Tools to Stabilize: Alchemist’s tools, Poisoner’s kit, or equivalent.
• Storage: One (empty) vials per dose.
• Access: A recently slain creature with a poison attack or be identified to have venom glands.
• Time: 10 minutes to extract and (optional) 10 minutes to stabilize

1: Extract

For the next 10 minutes, you carefully dissect a recently slain creature to attempt to locate and extract the source of its venom without poisoning yourself in the process. This assumes the creature is Small or Medium size. For a different creature size, refer to the table below. The Shelf-Life of this venom is one day unless stabilized (see 1.1 below). Roll a Survival check or a Nature check versus the same DC as the the poison:

• Critical Success: Extract 1d2 dose of venom.
• Success: Extract 1 dose of venom.
• Failure: No usable venom is extracted.
• Critical Failure: As failure, but you may poison yourself in the process; Roll a save vs the poison DC or become afflicted.

1.1: Creature Size

The size of the creature you are trying to extract venom from has an impact on the quantity harvested. Use this table to adjust the number of doses harvested, assuming you have enough empty vials to do so. As a reminder, an empty Vial is 5 CP and holds 1 ounce of liquid.

Creature Size	Number of Doses on Success	Number of Doses on Critical Success
Tiny	none (sample too small)	1 dose
Small or Medium	1 dose	1d2 dose (1 – 2)
Large	1d2 dose (1 – 2)	1d2+1 doses (2 – 3)
Huge	1d2+1 doses (2 – 3)	2d2 doses (2 – 4)
Gargantuan	2d2 doses (2 – 4)	3d2 doses (3 – 6)

2: Stabilize (optional)

Use Alchemical knowledge to attempt to stabilize the poison’s shelf-life. This procedure may not be repeated more than once per dose. For each dose, roll a Crafting check using the same DC as the poison.

• Success: The dose become fully stabilized with a permanent shelf-life.
• Failure: The shelf life remains unchanged.
• Critical Failure: You incorrectly mixed the ingredients; The dose permanently looses all of its potency.
