Based on the way most things like this have been coded in the games and the way the data files label two of the effects, I would say it would be a straight linear add for a net -70% on the threat generated. Here are the listings for the 2 cases that do show the buried identiification for the mods:

Notice that these are referred to as additive modifiers. What can be important is that in many cases some of the modifiers are considered to be of the same class and that usually on one modifier of that class can be active at one time. Since I could not find a listing for which modifier the Master Demologist (Imp) using, it is possible that overlaps one of the other two but I doubt it. If it does, then at some point you might be getting a message that a more powerful effect is already active.
