Does vampiric focus stack with all levels?

[Venon]

I've got a very dumb build for intimidate happening, leading me to think about dipping into keeper of constructs inquisitor and vampire hunter to demoralize undead and constructs, then thug rogue to frighten, then put the rest into fighter for Feats. My question is, vampire hunters vampiric focus doesn't seem to state "vampire hunter levels," so does that mean they stack with total levels? The hunter class has something that's stated similarly, and theirs is arguably more powerful because they can select which they use.

unless specifically called out.
class abilities the function based on levels use only the level of the class that gave the ability for it's level depended abilities.

Yeah, there is generally an unwritten assumption that whenever class features refer to level they're referring to levels in that class only.

For an example of something different occurring (it's not common) look at the Oracle's curse class feature that calls out that for the effect of the curse your non-Oracle levels count for half to determine the effect of the curse.

Unless the class features mentions something like that, it's only referring to class levels in the class that provided the feature.

Channel Energy: If I have this ability from more than one class, do they stack?

No—unless an ability specifically says it stacks with similar abilities (such as an assassin's sneak attack), or adds in some way based on the character's total class levels (such as improved uncanny dodge), the abilities don't stack and you have to use them separately. Therefore, cleric channeling doesn't stack with paladin channeling, necromancer channeling, oracle of life channeling, and so on.

The Vampire Hunter comes from The World of Vampire Hunter D, a Paizo product that isn't included in AoN. I have no idea if that setting has some setting-specific rule for stacking abilities, but, if you are playing in the Golarion setting, it requires some careful evaluation by the GM before allowing it.

The Inquisitor archetype Vampire Hunter doesn't have a vampiric focus feature.
