To my understanding BHE's "100%" text is really just referring to abilities with guaranteed effects such as "Inflict 2 Physical Burns on all enemies." Abilities written like this will not suddenly be reduced to 25% in this case. It should be triggering as long as the base percentage value of the ability is less than 100%.
Yeah, thanks for taking the time to clarify good questions like these!
