[DF] Poison Innate Attacks and Multiple Doses

[VariousRen]

I have a druid character in a DF game who has just taken a viper familiar (The familiar is straight out of DF: Allies). This means that both her and the viper have fangs that deliver poison, but I'm not entirely sure how multiple doses of the same poison being delivered to someone should be handled. Basic handles normal poisons by having each doubling of a standard dose give -2 to resistance, x2 to damage, and halves time between cycles. Does this same treatment apply to poisons that are built as innate attacks?

There is no particular restriction on the poison, so I would say that multiple doses would be cumulative.

Unless otherwise modified, the default would be having multiple instances of a Cyclic Innate Attack each have their own damage "ticks" and resistance rolls.

Is there any canonical modifier for treating it like mundane non-powers poison? It seems like it might just be called a +0% feature, being a combination of the All-Or-Nothing limitation (one resistance success ends all doses of poison) and a harder Resistance roll (which is worth -0% once it hits HT-6 anyways).
