      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?

        • Poison not practical?19 Apr 2016 15:45  

          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 00:51  

            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 11:42  

              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. <br/><br/>If anyone can share your thoughts/experience that would be great.

              • Poison infused poison weapon...13 Apr 2016 23:51  

                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.
