jumpman has such a way with words...
however, i still disagree with the second b in STABbed. while we're still treating it like a noun or verb or adjective or whatever it is exactly we want to treat it like, it is still an acronym for same type attack bonus (which cannot be "-ed" ironically").
it looks unnatural despite the logic behind it. i'm not sure i can give as logical an explanation as to why it shouldn't have the second b but i agree with mekkah, sirspanky and hyra.
kudos for taking the time to write this out however we end up spelling it though, perhaps helpful to put everyone on the same page for editing analyses.
