How long is the cooldown on buying the free rank up at the tavern? Need to get to pirate legend within a certain deadline but depending on the cooldown it might be mire time effective to save it for the last ranks
Well prior to the addition of the Seasons, it was once every update, so once a month. With the addition of the Seasons, I believe it is still the same, so every smaller update with each Season, which is once a month. I don't think it is once every season but I'm not sure.
