Unaugmented AF2+2 Storage

[Calatilla]

If you have the trial started then you either can't store them or you lose any progress on that item, like you would for AF3 pieces.

20k. Unless you imply using +100% exp rings. It's not a very difficult or time-consuming trial since you're doing dynamis anyway. Not quite sure why you would upgrade to +2 in the first place though, if not for the augments. Most of the stats pale in comparison with emp +2 or VW gear.

I did mean 20k yes, I forgot exactly how much exp it was. But as others have stated, not all of the AF2+2 gear augments are worth 20k exp even if the piece is worth upgrading.
