I literally was just in a very annoying boss battle in the Hardcore Mod I'm playing right now. It was the boss guarding Quadra-Magic and all the special Counter materia.

Out of nowhere, this message comes on screen and Vincent goes crazy. This has never happened to me before at all, let alone in a fierce boss fight. I have heard of it but never seen it or knew anything about it. I sat there with baited breath, waiting for when it would end and I'd die anyway. But it just kept going and going and going and eventually the boss was dead.

It was crazy. A miracle, even.
