Blight question

Hey guys, quick question. I’m pretty new and naturally drifted towards a poison build. I started looking up builds and see blight builds are super popular.

But what’s the deal with no one using toxic affix? Blight increases the damage of poison cloud 400%. Don’t you need at least 1 toxic affix to spawn the cloud?

Or does “poison cloud” in the blight discription simply refer to your poison damage in general?


Elemental Critical (legend affix)
Coat Proc (legend affix)
Wizardry (wizard talent)
Nova (mythic skill)
A.Drain Set
Vial has Coat skill

all of these has the ability to trigger poison cloud

Thank you!
