So far I have not encountered anything particularily different from 2015, but moogle vendors are selling "Fortune Fruit"
I ate one and got a 60 minute food effect. No idea what it does.
Edit: Well it gives +7 chr. Checkparam and stats show that as the only noticeable change.
Edit #1: Surprise! With opo crown it gives +7 to all stats, primary and secondary. No change in HP/MP/Ele Resist though. Why the fuck did SE take the time to program Opo crown interaction? I was not expecting that to work. SE never ceases to surprise me.
