ShiKage's Ultimate Hayato Guide

IT does give the buff, at i think a 60% rate? I thought it was broken too, but it does not activate as often as you think it would. You do get a significant damage boost when it activates and will notice a buff that lasts a short while (does buff durations increases make it last longer?).

I avoid sweeping sword as it fucks up the camera.

I don't know, I have Willow Dodge maxed and I don't get any buff and the increase in damage doesn't appear. I use the 15% total damage Beginner skill and I notice it but If I dc and cast Dankuusen for example I don't notice any change, even when I stay surrounded by mobs for like 2 mins...
