I've seen some people in game that have been mentioning they are in an FC that can't get rank 3 actions, do to not being able to charge them

With your Squadron once a week you can get 10 of these if you can do the level 50 Squadron Mission 'Infiltrate and Rescue'

It costs 3000 grand company seals per attempt of this.



There's also an earring you can get from a Bozja achievement for getting 1000 actions checked there. They're fairly easy to farm, and many are cheap on the marketboard that will give you some boosted EXP at least during level 80 to 81
