I'm not really arguing the ruling as it does seem clear in this particular card...but it does create some weird sub-phase of timing that could make other cards have some strange interactions. Each resolution of a die creates a "window" for actions that trigger on dice resolving correct?
Yes, each die resolution can potentially be the trigger for an ability or effect.
This is pretty well covered in the RRG. Look up triggers and "limbo".
FFG has actually done a very good job of laying out the terminology for this game. Many of us have been playing games that use similar words and we make this mistake of thinking other game's words and actions apply to this game. This is never the case! I'm guilty of this as well. I have noticed that every time I have raised a question about the rules it is because I was assuming something to be true rather than just reading the rules for what they are.
