Companion Ranking

[AridElf]

I was curious as well I know Rank 10 is the highest, but I was leveling THM from 18-26 an my chocobo went up to rank 2 and 3/4 I was doing like 50 FATES back to back to back. had like 9000+ maelstrom seals.

I wish there was a way to spend yp their ranking like doing Chocobo missions

There's a GC buff that increases companion exp gains by 5% but whether it's worth using I don't know.
