Gaining poison immunity?

[Imattackingthedarkness]

One of the PC's in my game is a human rogue using the poisoner build. He had asked if there was a way for him to gain poison immunity by ingesting different types of poisons. And eventually ingest so much of it that it would make his blood toxic so that he could poison his weapons using his own blood.

I'm 90% positive that there are no rules on whether or not this is possible, I'm a fan of the idea but it seems like it would be a rather high level thing to be able to do. Has anyone done anything along these lines or have any ideas for a house rule to allow this?

Seems more like fluff descriptive stuff that might explain a power/ability gained elsewhere..

The wildblooded serpentine bloodline (Envenomed) gives weapon licking as a 3rd level bloodline power. That sounds exactly what he's after for the 2nd part of the effect. (But would take 3 feats for a non-sorceror character to achieve (Skill Focus, Eldritch Heritage, Improved Eldritch Heritage)

As to the poison immunity... not sure if there's a blanket immunity option out there, but given his description on how he's going about it, sounds like you're after something like the Poison Resistance racial trait... perhaps allow him to switch his bonus feat or skilled trait (both 4 rp points in the race builder) and switch it out for the Poison Resistance trait (3 rp points). Hell toss in Plagueborn (1 rp) to even it up if you're feeling generous...

Poison immunity is a druid class feature at lvl 9 or alchemist at lvl 10. I could see it as an advance talent.

There is a prestige class from Paths of Prestige that seems dead on here Daggermark Poisoner .

Edit: apparently my link skills are poor. Looks like they are calling it a Guild Poisoner on the d20pfsrd site. Link should work now.

I thought there was a rule that creatures are immune to their own poison, but I went looking and couldn't find it. If anyone can point to where that particular rule or something similar might be found, it might be a useful guideline.

That's a good idea, the character is still being made and I hadn't thought of using the race builder to make a sort of "variant poison resistant human."

For the bloodlines, do you have to be a sorcerer to select the bloodline feats?

I think there's a race in Advanced Race Guide that has toxic blood.
Vishkanya, if i'm not mistaken

Thanks for the input, I reread the sorcerer bloodlines and the eldritch bloodline feats and I understand them now. I've never had a PC show any real interest in poisons, but he's become absolutely enamored with the poisoner rogue build. I'll show him all of this and see if it is what he's looking for.

You could make him actually go through the process of poisoning himself, rather than make it a class feature. For instance, every time he poisons himself, and makes the save DC (but not by too much), he gets a +1 bonus to saves against that poison. And after 5 or 10 times, he gets complete immunity. Let him actually put himself on the brink of death if he wants it that bad.

[Imattackingthedarkness]

He had suggested taking poison repetitively and once he had taken ability burn equal to his constitution score he would be immune, he would obviously need a cleric or something to restore his lost constitution but seeing as we are just starting out I don't want him to kill himself before we really gt the chance to do anything.

Toxic, in the race builder, is only 1 rp standard offense trait (though you'd have to handwave the racial requirement, or perhaps have it cost more rp for races not listed). And it covers exactly the ability to poison his weapon by licking or bleeding on it thing.

Poison Resistance, as mentioned, is 3 rp standard defense trait. Although not 100% immunity, at +1 to saves per HD, it does mimic his descriptive fluff about slowly building up immunity.

You could then trade those 2 abilities in for an equal number of rp points taken out (say the (4 rp) human bonus feat). And you'd still be sitting at a 10rp standard race. No fuss no muss.

The Eldritch Heritage feat chain can mimic the one ability as mentioned, but at a rather high feat investment that doesn't reach fruition until level level 11 (and includes the fang bite attack which might be a bit too over the top)

That's excellent! Should be just what he is looking for!
