Looking over what Orangemushroom posted, I'm kinda confused about a couple of things. Post-Union, Arans have physical training, that Maha party buff and might, right? Also, do you get anything if you already passed freeze standing 30/high mastery 30/high defense 30?
Most importantly, it says "Combo Barrier: now increases party’s defense and magic defense by 60". That's in addition to the percent mitigation, right? Like, it's not the worst skill in the game post-union, is it?
