The italics part didn't quite make it to implemented. Right now it looks like [ individual spoils ] are bold and bracketed while [ teammate spoils ] are just bracketed. That seems sufficient to me, but why not further distinguish them with the italics?
A further idea that I had, that could be put forth as its own suggestion or part of this one is to put a little bold asterisk by [ teammate's spoils ]* denoting ownership.
[ My spoils ] [ Teammate Spoils ]* Other Team Spoils*
