I’m not a huge fan of side-effect mechanics. I find they usually add more complexity than benefit. They can be jarring if the side-effect is something fairly removed from the original thing being resolved. Side effects have to be balanced such that they work with the core mechanic, neither ruining its original feel nor making the secondary effect insignificant. In short, the whole concept is troubled from a design perspective. Still, there are times when it’s completely appropriate. Where and when is the key question.
