How would you price this.. unique treasure?

[Three_Haligonians]

Without getting too much into the story, one of my players just found out that the experiments her characters mother carried out on herself have manifested themselves in the character and now her blood is quite poisonous to vampires.

Here is what I have so far:

Libris Mortis: The positoxin Liquid Mortality costs 1,250 gp per dose.
Dragon Magazine #322: The Silicon Sorcery Article is about enchanted poisons. One such enchantment is to maximize the damage done. This costs 15 times the normal cost of one dose of the enchanted poison.
Dragon Magazine #312: An article on assassin PrC's includes the Poisoner, one of the abilities granted is the ability to create a poison that deals its secondary damage one round later instead of one minute later. This costs 4 times the normal price of one dose of the selected poison.

So:
1,250 gp x 15 x 4 = 75, 000 gp for one dose of this suped-up poison.

Now, I figure that since a Vampire blood drain attack deals 1d4 points of Con drain, the average roll is 2, thus I have so far valued this "ability" at 150,000 gp.

However.
This "poison" only works on vampires (instead of all undead like regular Liquid Mortality)
It only works when a vampire drains blood from the character, she cannot "bottle" it in anyway since once it leaves her body for any length of time it becomes inert.
The Fort save involved is DC 30 (The DC of "real" liquid mortality is only 20)
Finally, since it is her blood, the character has a virtually unlimited supply.

Given all the above factors, how would you alter the current price of 150,000 gp?

Thanks for your help,

Can you please post the actual effects of the poison on vampires? It's hard to tell- you posted pricing guidelines, but I'm not certain what exactly I am pricing.

Interesting idea, and you've certainly done your research!

Why do you care about pricing it if there's no way it can be bottled and used?

Sure.

Liquid Mortality Injested DC: 30 Initial Damage 4 Str Drain Seconday Damage 8 Str Drain.

I've already mentioned how it is different from the Liquid Mortality printed in Libris Mortis, but I forgot to mention that if it brings the undead creature's Str score to 0, they are destroyed.

Well, it is pretty non-standard treasure but treasure nonetheless and so I'd like to know how much it is worth so I can keep the treasure level of the group balanced.

While I can understand the need to keep the treasure level balanced, this seems like something beyond the player's control that is of questionable value to them. Honestly I wouldn't count it as treasure. If there's an imbalance of "wealth" between players, then you should maybe come up with some interesting thing for each of them as well. As is, this is only essentially a self-defense against vampire bites, probably not worth even as much as a feat unless the campaign is VERY vampire-centric.

Just my thoughts.

Well, since undead are immune to poison, technically, it should be worth 0 gp. But I'll ignore that. I am curious how the original poison (that affects all undead) would work against, e.g., skeletons, who can't really ingest anything.

1,250 gp x 15 x 4 = 75, 000 gp for one dose of this suped-up poison.

Now, I figure that since a Vampire blood drain attack deals 1d4 points of Con drain, the average roll is 2, thus I have so far valued this "ability" at 150,000 gp.

So you're saying that the vampire gets a dose of this poison for every point of Con he drains?

It only works on vampires, rather than all undead. Unless you have a vampire-heavy campaign, multiply 1/4. If you have a vampire-heavy campaign, let's say 1/2. 37,500 or 75,000

It only works passively. Furthermore, she presumably still has Con drained. Multiply by 1/20. If her Con isn't drained, multiply by 1/10. 1,875 or 3,750 or 7,500 gp

Unlimited? Honestly, because it's passive-only, I don't think it matters much. Multiply by 1.

DC 30. Multiply by 1.5. 2,812.5 or 5,625 or 11,250. And even that seems a little high.

Libris Mortis has special "only works on undead" poisons called positoxins. Liquid Mortality is one of these. I like your math, it's just what I needed,
