I don't what that maintenance was about but 55 gems is very welcome.

Anyway, someone know how exactly the 66 event equipement bonuses works? Old equipement gives ATK buff, springs ones gives DEf and summer gives healing/HP but I don't get how I'm supposed to get them. I thought it was at 10/15/25 equipements on the whole party but even with 10 equipements, it seems I don't get the bonus.
With 15 mixed equipements, I managed to get +10% ATK. That's a bit unclear for me...
