You only get any BP rewards at the end of the mission after you hit the reward screen.
If you've ever looked at a break off you'd notice it's a black drop with a question mark floating over it.
This break off item is only available for pickup after beating the boss.
Break off rewards are stated as "Obtain ______ (break off)" meaning you have to pick up the item, not just knock it off.

So in short, if you want the item or BP reward you will have to use up tokens.
For titles no :o
