I read through some Reddit post and saw this one response that triggered my interest. They said the sch skill looks allot like haste since it has the sound kinda like how fey wind use to sound. With the little lines too so of course I went back to look and looked a few times and it does look like some kind of buff. Could be haste. Some people also said it could be an upgraded excog. I don’t think so. Excog works beautifully now so there is no reason to change it. Unless they will add the haste effect to excog as well. So idk lol. I hope it is haste tbh.
