Sorry to add another picky point to the recent rewrite of the Radioactive skill's description, but as it currently reads, 'If a radioactive die is either the attacking die or the target die in an attack with a single attacking die and a single target die, the attacking die splits, or "decays", into two as-close-to-equal-sized-as-possible dice that add up to its original size.' That means that a Trip die targeting a Radioactive die with a Trip attack should decay regardless of whether it succeeds or not.
Is that what actually happens? Should it?
Or should that text be changed from "in an attack" to "in a successful attack"?
And of course, if we eventually have dice that are both Trip and Radioactive, should they decay when they make an unsuccessful Trip attack? [Edited to add: Well if I'd've looked more carefully... we do have one such die, in NoopMan. See below...]
