[TheSpoonyBard]

Emerald weapon may have been killed in 10 seconds, but how long does it take to kill 65,535 monsters?

Not long at all if you augment Vincent's kill count with a code.

And is that total or just for Vincent?

65,535 just for Vincent.

And what did the info bar say?

It's just the normal description for 4x-Cut.
