I have already got that bonus. It is the enemies that drop them after you get a nice but Drippy will throw them out too, sometimes with wanton abandon but never when it's useful.
@Mr_Sleep - Mr. Drippy has a useful life-saving special, which you get later on, which has saved me from a scrape or two. Also, you can increase the number of orb drops by completing errands and bounty hunts to get the merits needed to 'purchase' that bonus.
And I thought it was the enemies that dropped blue and green orbs, as well as miracles, whenever you pull of a Nice! move? I didn't realise it was Mr. Drippy dropping them.
In the boss fight I would get one small blue orb after successfully defending and getting a 'Nice!'. That small blue orb isn't even enough MP to heal.
You are a factory of sadness.
