A thought I had, when discussing Chaos Stars.
It would be interesting to use Chaos Stars like "Righteous Failures" ... in a matter similar to [Y] and Righteous successes.
In essence, treat it as a Challenge symbol (or maybe just a bane symbol) and roll an additional <P>. This seems like it could provide for some dramatic "negative" tension on a roll. It also might help to mitigate the success rate, for those who think the success rate for PCs is too high.
Thoughts?
