Stoneskin and poison exploit

So I was at the chess board in Durlag's tower about to kill the king, whose defenses are down and all alone. He summons a giant spider which goes after Neera. "No worries," I think, "thanks to her wild surge she has a level 12 stoneskin up. That 8 legged fiend can wait til the king is down." I go back to killing the king but then Neera grunts in pain and I notice she's dying fast. Stoneskin is still up so I pause and scroll through the feedback notes to see what happened. Turns out that spider can't hurt Neera but it can still poison her...and she's dying a slow painful death while Viconia can only watch from the other side of the board...admittedly she'd probably just watch even if she was by Neera.

I reload (because I'm like that) and test to see if this works in my favor. I send Dorn up to the King who has stoneskin up himself, use Dorn's poison ability and let him whack away. Sure enough, Dorn connects, does no damage but poisons the king who quickly succumbs to his wounds like a...well, like a spindly wizard that just got poisoned by a 2-handed sword.

My question: is this an exploit/bug? And if so is there a way to fix it (mod or otherwise)? I feel like if Stoneskin prevents a weapon/spider bite from actually wounding the flesh then the poison should be a no go as well.

    It's "normal" i guess, poison dammage is like elemental dammage, it bypass Stoneskin (like the elemental dammage from Flail of Ages). It's a legit counter and strategy against arcanes users. Note that poison also bypass mirror image sometime.

    PS : Vampire Level Drain ability also bypass Stoneskin and that hurts !

    I don't know if it's how the abilities interact in PnP, but yes, in BG Stoneskin has only ever blocked physical strikes. That's part of why experienced players love weapons like Flail of Ages that have added elemental damage, because it goes straight through stoneskin and can heavily damage and interrupt enemy casters.

    Well, it makes sense that stoneskin would not protect against poison, though I would ask that it requires some damage to be done to the spellcaster so that the poison can actually contact the spellcaster.

    Perhaps it's an insidious poison that seeps through the skin even if it's been hardened. Kind of like how you can still take acid damage with stoneskin up.

    Yes, but that's the point. Poison shouldn't be able to connect through stoneskin, which it currently does. If it has been connected, then applying stoneskin shouldn't stop it.

    Stoneskin does indeed only stop the physical damage component of an attack, letting non-physical components like poison, elemental damage etc through. This is in contrast to Protection From Magical Weapons which will stop any and all on-hit effects a (magical) weapon might have, even Carsomyr's chance to dispel.

    Are you sure you didn't just land a hit? Because with Mirror Image there is still a chance to hit the real mage.
    Yes you're probably right.

    For the fact that poison is bypassing Stoneskin i agree that RP wise it's strange but it's like that, like @Shin said, use PFMW to protect your mage from Poison / Level Drain / Devour Brain abilities

    @Shin Good to know that PFMW protects against all on hit affects - I had never really used it in previous BG2 playthroughs so that gives me something to look forward to this go around.

    @MadHax That's a good point about the Flail of Ages, I have used that tactic myself. And that also makes me realize why the poison goes through Stoneskin. The spell clearly states that elemental damage is not stopped so it has to allow those on-hit and I'd imagine it'd be crazy difficult to code elemental damage to affect it but not poison. It seems like it's an all or nothing thing (like with the mentioned Protection from Magical Weapons).

    The more I actually think about what's involved in bringing the already convulted AD&D ruleset into a set of computer code the more respect I have for Beamdog and all those modders out there. Mad props.

    Looks like this was an intended change. To confirm what others have said the idea being that elemental + acid damage already bypass both Stoneskin and Mirror Images, so poison should as well (not saying I agree with this but this is just what I've read).
  • AranthysAranthys Member Posts: 722
    In vanilla, stoneskin prevented poison but not elemental damage.
    So, no, it shouldn't be crazy difficult :)
  • FlashburnFlashburn Member Posts: 1,847
    Since Dorn shares his name with his good counterpart Keldorn, I like to think of his Poison Weapon as the evil version of double-strength Dispel Magic. It might not remove buffs but it neuters mages just the same.

    Try it out, likely the most efficient protection spell there is for wizards.

    It's not an exploit, as Stoneskin is meant to only protect against physical blows, not ailments. Pretty sure Insect spells can affect Stoneskinned mages too.

    EDIT: Huh, I didn't know that it prevented ailments in the vanilla version. Learn something new every day.
  • MeepichiMeepichi Member Posts: 40
    think of stoneskin as your regular skin just very hard. It still can feel heat,cold,etc and still can absorb poison.

    I kinda wish the Wizard Slayer's Miscast Magic on-hit got through PFMW. Nobody would consider the class underpowered, then. Improved Haste a Wizard Slayer and suddenly it doesn't matter WHAT your contingencies have in them!

    Just discovered this and I think its ridiculous. Poison should not pierce stoneskin! its internally applied damage not external like fire cold or lightning, you have to actually pierce the skin to poison. Elemental damage through stoneskin makes sense this just feels like a bug and a very annoying bug at that.

    Also I noticed when having one of your mirror images hit you still get poisoned....how...wh....what!?
  • DreadKhanDreadKhan Member Posts: 3,857
    Poisons dont have to be delivered only by injury. Skin is pretty porous, really porous in certain areas, but hardening your skin shouldnt protect from poison unless its very weak (ie requires an actual injury to take effect). Even if very weak, you really just have more time to wash it off.

    Also relevant, many toxic compounds tend to be harmful to skin as well, ie corrossive. Lots of toxins can create their own injury, basicly.

    3rd edition did a good job with poison overall, but imho contact poisons delivered via injury should have a DC bonus...+2 at least. Thieves' World had slow acting poisons too, very brutal. They work like diseases, pretty lethal.

    Think of poison like any other status effect (like getting diseased or stunned). I believe those bypass stoneskin or mirror images if a hit is registered (even a hit against an image), so it only makes sense that poison does.

    But if that doesn't help as DreadKhan pointed out there is such a thing as contact poison (even in 2nd edition dnd). The game however won't distinguish between say the poison found on your assassins blade, vs the poison damage from a wyvern. They do different amounts of damage but they would be both treated the same way in terms of their bypassing of mirror image/stoneskin.

    As much as I despise mages and thoroughly enjoy anything that brings them down, I do agree with your point.

    But the game makes several explicit references to poison needing to be injected though (such as in the assassin's and blackguard's kit descriptions), so it seems incongruous that poison can be equally effective simply by spilling it on someone's (magically hardened) skin. For the reasons Mush_Mush stated, I don't think it should get the same treatment as elemental damage.

    Most poisons require to be introduced into the bloodstream to be effective. For this the skin must be cut , scratched and/or pierced IMHO. I think bg handled it better in vanilla, you can't get poisoned until the attack actually hurt/bled you (your stoneskins expired)

    Unless we are talking about the 'poison is corrosive/acidic' trope. You know, on tv an evil poisoner concocts a vile poison brew and the metalic spoon dissolves inside the container. (but how does the container remain unaffected, is a mystery) Poison that potent will have a nasty effect on human skin. It can burn off the layers of skin (thus, can even bypass stoneskin) and seep into pores and into blood. Most chemical poisons are dangerous and deadly like this. However, although I am not an expert, I don't think most natural poisons (spider, snake etc) are that potent. I have heard about poison frogs that kill man on contact with bare skin, though. And some snakes just spit the poison in your face.

    In DnD, poison is handled in seperate ways, there is 'contact poison' which does not require a cut/wound to be effective, just touching the skin is enough to do its work. I guess bg poisons just became 'contact' poison in the enhanced edition, other than the regular 'wound' poison.

    Stoneskin is powerful enough as it is. It's good that some stuff goes through even if it doesn't always make sense (you can think about how it makes sense for poison and elemental damage, or for the Celestial Fury's stun effect, but the mindflayer intelligence drain and the vampire level drain? nah)

    Fire, lightning and cold, (and acid) does not require an open wound to effect the target, they just damage and hurt you through your skin. Similarly, a vampire's touch drains two levels simply because of the monster's unnatural connection to negative energy plane. A vampire can drain levels from a pc just by shaking hands with them. In bg they claw and bite and slam because well, why not, we are in combat and they have great strength to put the hurt into their natural attacks.

    Actually, the mindflayers int drain is BG's implementation of extract brain, which is supposed to require a single mindflayer to grapple the target with all 4 tentacles, then it can extract the brain for an instant kill. Its meant to be a physical effect so it should be effected by stone skin.

    As its implemented, its also ludicrously overpowered, requiring usually only 2 or 3 hits within the space of 5 rounds from any mindflayer, not 4 grapples from the same mindflayer. Given that they have 4 attacks per round, a 5 round window and they come in packs of 4 or 5 in most cases, its far easier for them to instant kill than in pnp. Even if they can only hit on natural 20s, its still very possible for them to kill you with int drain, given that between them, they will be making 16-20 attacks per round. In pnp, extract brain is mostly only done on incapacitated targets, and is very difficult to pull off against a high level warrior who isnt incapacitated.

    Are you sure @lunar‌ ? Most poisons work by being in the bloodstream. How can they readily get into your bloodstream? Injury, skin contact (this is how most industrial pesticides work), breathing them in or eating them. They all end up in your blood, and thats how most work. Poisons in contact with any mucus membrane will absorb toxins very fast, probably faster than an injury, though slower than inhaled. This is incidently why these areas are vectors for infections as well... and why comparatively frail virus' like HIV are still transmissable.

    Assassins and blackguards arent using 'natural' poison, as most venoms are chemically very unstable. They store very poorly, since they typically are not stored by the animal, bug, etc. Poisons made by humans tend to be pretty good with storing, though many liquid forms will seperate eventually. Suspensions will settle too. Anyways, if you are making an injury type poison, anything that makes it easier to take effect is beneficial. If you can mix in anything corrossive, you probably would try it. Test it on rats, calculate your lethal dose per kg and you're good to go! Note, injested poisons can be vomited, so dont overdose too ridiculously.

    For the Mind Flayer, disturbingly enough they dont use brute force to remove your brain, they dissolve skin and bone chemically via tentacle secretions, then voila! Readily available brain. Stoneskin doesnt protect against corrossives, so Mind Flayers should bypass it. Some inconsistencies in source material though.

    Mind flayer attacks piercing stoneskin I don't mind so much (altho I wouldnt shed a tear if it changed lol) nor acid attacks, and any gaseous forms of poison (ie. clouds, dragon breath etc.) i feel could plausibly poison you but I still believe any poison that needs to be delivered in a physical attack should be blocked by stoneskin and I can't see how it can be explained otherwise. Yes some poisons may be corrosive but imo that just slides it into acid category not poison.

    I'm still going on the assumption that the mirror image thing is a glitch cuz my mind would never be able to comprehend the logic in that that decision if it wasn't xD.
  • elminsterelminster Member, Developer Posts: 16,317
    I imagine the mirror image thing is more an issue of mechanics. How to make it so that the game recognizes that you got a "hit" against the image, but that that hit doesn't mean that the real target gets a poison effect active on them.

    But I mean if elemental damage and other status effects can bypass mirror images then I don't see why poison wouldn't.
  • dreambleddreambled Member Posts: 48
    I think this is just one of those contradictory situations where rule-makers and game-makers don't care to know the difference about everything in play. For example, in the real world, poison is not injected (that is venom), it can either be ingested or simply touched to do it's work.

    Stoneskin is described in the game as an outer skin that completely covers the caster. It is of course magical, and made for the purpose of protecting against physical attacks. It would make sense then, that something like poison, something that is not a physical attack, would still affect someone who has this spell on them.

    Though, again, the people who make the rules don't pay attention to the difference between poisonous and venomous, as the OP pointed out, it was a spider did this to Neera at first. Spiders are prime examples of being venomous in the real world, not poisonous. So in that since, it should not have been able to work, as spiders need to inject, and their mandibles should not be able to pierce through stoneskin.

    Sooo .... ¯\_(ツ)_/¯
