It has Crocea Mors as a name, so obviously it does something cool at least. I'm guessing maybe something like:

1) When he fills it with Aura, it unlocks into a second, more formidable form.

2) Summons lightning bolt?

And about Ozpin, I was kind of hoping it wouldn't be that obvious, but if you got by rule of elimination he is the only kind-of main character that can be eliminated without the RT HQ being burned down by crazy fans.

The real question is: Will he die this Volume? If that is true then it'll seriously be the most epic (and unexpected) thing to happen in RWBY history, ever.
