Thanks, but not what I was after. Okay, third time explaining.
'Red' has Status A,
If 'Blue' hits 'Red' while 'Red' has Status A on,
then 'Blue' gains Status B because they hit 'Red' with his status on.
So I think I need to find some kind of 'on hit' trigger and set an if target has X status, then do X. Any idea where or what I'm looking for trigger wise?
