Hi There
Maybe you know Linkens Boomerang:

It is possible to disarm Ragnaros in MC with this, but thats already known. What I found out are the Dogs in MoltenCore, which lie down before they die with some HP over can stand up again if you throw your Boomerang on them. But they do nothing, just stand there and looking on you, however, it was funny to fool some MC mates.
