          There's a Poison gem in Painted World of Ariandel, first bonfire before the collapsing cliff, far left next to the 1 bug.

            In pvp, always try to use this gem as a support for bleed. Whenever the bleed proc occurs, what's left is a sliver of health that stays there until the enemy player runs out of stamina for running and proceeds to chug.

              I just wanna add that Poison gem also increases the bleeding of weapons that already has bleeding on them.
              i.e. Barbed Sword ; Flamberge ; Bandit's Knife ; Carthus weapons ; and ESPECIALLY spiked mace that adds quite a bit bleeding and poison than most other weapons.

                Tested on Rotten Ghru Spear +10 @ 99 luck, NG; the poision proc rate maxes out at 100, I can manage to poison enemies such as the 'pike' wielding villagers in crucifixion woods with a single r1. Additionally the 'Charge' weapon art on the giant crab next to the crucifixion woods bonfire can proc poison in a single attack if the player uses the strong variant of the weapon art where you press r2 halfway through the animation to lengthen its duration and increase its total amount of active hit boxes; I should note that when performing the 'Charge' weapon art it is vital to land as many of the weak hit boxes as possible as seen evidently when using the weak variant of 'Charge' on the giant crab- poison does not proc. Interesting utility combo for luck builds

                    it increases the bleed effect on weapons that already have the bleed effect like claws katanas warden twinblades ect.

                      So I'm a sorceres/miracle worker and I just got enough dexterity to use the brigand twindaggers, I was going to put the Crystal gem on it because of my high intelligence, but I feel the poison gem would be better because it'd make a quick poison build up, which should I use?

                        Am i the only person who sees the great value in poison weapons for their ability to essentially negate tears of denial?

                          The thrall in the dreg heap that has a poisoned Flamberge can also drop these. The other ones might be able to, but I've only gotten one from that one.

                            Poison can now be applied to enemies very fast now, good for bosses and tanky enemies to apply to at the start and then switch to your primary weapon.

                              K so what's good after the patch? I've always been interested in underdog poison builds. Amy weopons that have an absurd amount of poison and are fairly fast? I'm talking besides daggers. I've had luck with the poisen brigantine duel dagger. Now wondering if there is something with a little more reach

                                  When I went to enchant my +10 Uchigatana I hovered over poison Gem and saw it upped my Bleed value by one as well as adding a poison value. Can anyone Confirm this?

                                      Just don't use it as main form of offense. infuse your side weapon with poison, apply it and swap to your main weapons.

                                        Poison not practical?19 Apr 2016 21:45  

                                        Poison in other Soul games was at least useful in PVP. But in DS3 I don't see it as being practical unless there is a way to stack/buff poison damage. Until then poison builds are not going to be a thing in the game.
