To be honest with you, I don't like this weapon compared to the Okina.

The Slash Damage on the Ether-Daggers is appealing, combined with Virus and the higher natural Statuschance may give it a slight benefit over the [Okina], which has a higher crit chance and crit multi.
Slash and Virus as proc can easily tear through HP, first by halfing it, second by adding 1 stack of 6 sec slash proc.
However, when dealing damage in the 1000's, the difference of x0.2 on a crit actually does matter, even when going into the orange/red crit territory.

But, if your aim is to leave bits and pieces of enemies everywhere you go and have fun sending Gore flying, you have come to the right place.
The [Ether Daggers] have 70% of IPS as Slash, now let that sink in.
