Inner Ability Buff Duration. Keep or Keep Trying? So I was wondering if 19% buff duration with a 2% total damage on normal monsters is worth keeping. I have the Mech S rank card so that gives me 15% with the Cedes Card that cuts the cooldown by 5 secs. So right now, I have to wait around 6-7seconds to recast Final Cut. What do you guys think? Keep or keep trying to get a better buff duration?
