Poison rules, stacking and reasonable belief

[blue_the_wolf]

Im wondering how people feel about the Pathfinder Poison rules.

we have always played that the DC of a poison stacks with each dose.

we never questioned the rule hell we never even thought about how long this stacking applies we just figured if in the course of a battle a person was poisoned 3 times the DC would go up by 1 every time he was dosed ... basically that battle.

I just read the rule which essentially states that poison only stacks if your already poisoned having failed the save before.

This is not a rules question or even an argument. its an opinion question... Do you think this makes perfect sense or can be handled better?

I find it hard to believe that a person with a fort save of 10+ can be dosed with endless amounts of black adder poisons and would only feel a little ill every 1 in 20 times they roll a 1. even if they roll a one and get poisoned again they just have to beat the next save to restart the clock.

it seems right to assume that each dose would increase the DC so that enough doses of a poison pretty much ensures that the target will eventually suffer from it.

just wondering peoples opinion on this as I am considering setting the original plan in stone as a house rule if my players agree.

No, it's not realistic, but then again neither is surviving three strikes from an axe. Sometimes one has to make concessions for the sake of playability.

I've taken to allowing people to base their poison DCs on their Craft/Alchemy rolls. Otherwise poison becomes a nonissue at high levels, which irritates the heck out of me on either side of the table. My rule of thumb is adding 1 to the DC for every 3 by which the alchemist beats the initial save DC when compounding their blade venom (or contact/inhalation/ingestion vector, whatever). Keeps detect poison an active cantrip, and adds to the paranoid use of antitoxin...
