Two-part question regarding Attachments and Modifications answered by Sam Stewart. Answers inserted below:
1. When modifying attachments, does the difficulty increase with each subsequent modification (i.e. Hard for the first mod, Daunting, for the second mod, Formidable for the third mod)?
1. Yes.
2. Assuming that the difficulty increase is cumulative, what is the procedure for the fourth mod? Are more difficulty dice added beyond five, are difficulty dice upgraded to challenge dice, or is the Impossible task sidebar followed?
2. The GM is the final arbitrator as to which procedure to use, but generally I recommend that the GM allow the player to make the check, upgrading the check once for each increase beyond Formidable.
