Mod19 preview server:
According to the tooltip curse bite has no curse consume synergy, so it should work with power of nine hells feat.
However Curse bite does NOT add soul investiture with power of nine hells feat. Curse bite's tooltip does not say anything about being a curse consume encounter. So technically it should spawn soul puppets and stacks?!
Please test this yourself and read tooltip. IT used to work a week ago before the next preview patching.
