Yes, as weird as it sounds I have a scenario where some threats/adversaries will be armed with crossbows and explosive bolts. I'm confused though, as to how I create an explosive bolt/arrow with the listed AP/BD modifier of -1X/+1S. Arrows/bolts have a default AP/BD of 3B/3, so I'm wondering how that -1X gets factored in? Do I just start with an eXplosive that's equivalent to the Ballistic and then subtract the 1 from 3 to arrive at an AP of 2X, or do I do something else? As well, is the +1S added to an eXplosive equivalent of the Ballistic giving me a final BD of 4S?
Any feedback would be much appreciated.
