The guide listed in the forums is outdated, as we discovered that if a skill has multiple of the same entity, such as Blade Spirits or Wind Devils, the DoTs applied by them DO stack, and that has been the focus of multiple builds.
I would read through @Evil_Baka’s Pseudo-Pet Vitality Storm Totem Build guide and try to apply it for your build. If I recall, Grasping Vines does have multiple entities, meaning Grasping Vine’s bleeding damage would stack the more of them you have, but I haven’t heard of anyone really using a Bleeding Grasping Vines build to good effect.
Though since we’re talking Conjurer, the class is much more suited to attacking since neither class has any source of Cast Speed, so I would focus on going Gutsmasher Savagery, since it would be much easier to level with using Melee with Troll Bonecrusher than trying to combine some Bloody Pox + Grasping Vines monstrosity.
