    • I initially thought it was strange that occult weapons couldn't be buffed where in DS3 hollow-infused weapons could. But now that the game's been out a while, I gotta say that Arcane builds really DON'T need any more bleed/frostbite than they already have.

        Occult is a great choice for anyone already pumping Arcane for the Dragon Communion Seal. Very pleased with my +25 Occult Nightrider Flail.

          Very disappointed with occult, at 50 Dex/60 Arc I consistently find my AR lower with occult, even with the bleed buff it gets when compared to Keen + Buff excluding Dragon Communion seal which is doing wonky things to buffs, perhaps I'm just stupid but until R.o.B. and/or Eleonora gets nerfed I'll stick to it before respec.

            I feel like I’m missing out on how to effectively use this item. I’m a pure STR build, but when I add a phys ash (determination), I can add it as a blood affinity, but it still drops my STR scaling back to non-phys ash levels. So, no change there from pre-black whetblade.

            Conversely, if I add bloody slash, I can now add it as a Heavy affinity, which maintains STR scaling and gives me the bloody slash L2 attack…but no bleed attacks with R2/R2.

            Is this how it works?

              Occult weapons can't be buffed, even if they are pure physical. At first I thought this was an issue with arcane scaling weapons not being buffable, but varre's bouquet scales with arc, has bleed, AND is buffable. Why is it like this? I feel like Occult is just worse than keen + bloodflame unless you use Seppuku. This kills arcane build variety.

              • I was a bit disappointed that my arcane build wouldn't get Occult until Radahn and then remembered I could obliterate him with Rotten Breath. Dunno if it's too cheaty or not to do though

                  I have this but in the normal ashes of war, it's not applying poison affinity, I also have red hot whet blade and so fire affinity is available but poison isn't for some reason. Is this a bug or just me ?

                    It's a shame that Occult weapons that only get physical arcane scaling and nothing else cannot be buffed with sorceries/incantations.

                      This is a game changing item for anyone going for status builds. I stumbled upon it by chance after spending many hours searching for poison/blood whips and claws. With this whetstone you can apply a basic physical ashes of war that works for almost any weapon type (like war stomp, determination etc) including whips and claws and apply poison or bleed to them! Bleed/poison power stancing whips hoh baby.

                        there's also a red-hot whetblade down in caelid, in redmane castle if you go past the iron maiden guy and up the ladder
