Brionac - Protection

So is it established that Brionac lowers protection on some monsters? If so, which ones? And should this information be added to the main page?

According to Aubog, anything with /boss/ in their category. But that specifically would be hard to add into the page, since there are so many, and generalizing it will not work, since no one will know what /boss/ means.

I think the fact that it cuts protection on some monsters warrens a note on the main page. Anyone know that does the Brionac user has to be under the effect of Sock or Demi for it to lower boss' protection?
