Quoting this in case it was missed. Looking at the future goals for the event it seems that while a skill training goal shows up in phase 2, phase 3 has skill data use goals which is a bit of a gotcha if you used up your stash trying to meet the 10 skill trainings goal. Good thing that was posted otherwise planning ahead for maximizing what you get out of the event would be nearly impossible. Also it looks like I really need to level up a rifle echelon for midnight battles so I can work my up to 2-4 to unlock equipment calibration, my MG echelon gets too tied up on the bullet sponge enemies and ignores the rifles tearing apart my smgs in the meanwhile.
Anyone know when batteries show up in friend dorms? I'm trying to do the collect five friend batteries goal but I there aren't any currently available and I have no idea when to next check.
