        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

                        Poison is alright at low SL pvp26 Apr 2016 13:04  

                        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.

                            Poison has one use; if you apply it to someone in PvP, you will know exactly where that person is for the duration of the Poison effect.18 Apr 2016 06:51  

                            While enemies are poisoned, you can always see their health bars. But, yeah, if you only care about damage, yes, Poison is useless.

                              Is poison useless?15 Apr 2016 17:42  

                              Yesterday I infused my Caestus +2 with poison and even though I poisoned some monsters with 2 hits (several enemies seem to be immune to poison at all) it did 3 HP per second of damage, which is pretty useless considering that I do around 60 DPS per second by hitting with the weapon. If anyone can share your thoughts/experience that would be great.

                                Poison infused poison weapon...14 Apr 2016 05:51  

                                I am not sure if this applies to all poison weapons, however when infused with the Rotton Ghru Spear the effects seemed to be unnoticeable.
