FFRK JP - 10th Anniversary Party: free banner and Gift Dungeon

Today all fest dungeons have been unlocked, with the Music Record dungeons and the Gift one becoming available.
A free banner allows to select one elemental and one realm-based CSB+: too bad the new imperil ones weren't included in the pool, I already got all the older ones :')
There's also the daily premium banner, same gem cost but better rates for 7★ and 8★ than the regular daily one.
Banner 3 of the fest banners is open, with banner 2 still on.
The daily gift dungeon has a more stable structure, with only the Magic Pot appearing and 2500 exchange coins rewarded at each attempt.
