Finally, Legendary Legion. 36 attackers! Totally worth it, dood. I'm glad I was able to achieve this during the half off rank up event thing. If we didn't have this event, it would have taken another month.
I went with Buff Duration because it can be useful for some skills like Dark Knight's Sacrifice, Xenon's OOPArts Code, and a lot of other skills that I can't think of right now, but you get the point. It's actually 60% Buff Duration with the Mechanic Member Bonus.
I had to log on each of my characters to reset Hyper Critical Rate, and from what I've seen, Shade might have the lowest crit rate out of everyone at 20%. But with Legion, link skills and Decent Sharp Eyes, it's 100%. Every one of my characters can crit all the time now. This is amazing, dood.
