There is also a possibility that it is some form of special-based Anger Point since it raised Drampa's special attack in a pinch.
However, it is more likely a weakness policy-ish ability since Drampa's unusual typing could take advantage of it.
I do hope it's bulky enough to reliably set-up with it's ability(more likely) or fast enough for revenge killing after switching on a super-effective move(which I highly doubt).
