Avoid Random Battles
When your ship gets the upgrade that lets it fly in the high and low altitudes in the later half of the game, you can fly in those altitudes to avoid random battles with monsters on your ship deck. Keep in mind if you're aiming to get the three secrets you're probably going to have to make up for all the battles you skipped eventually.

Special Swashbuckler ranks!
Whenever you are at the rank of King of Rouges, you can begin qualifying for a special Swashbuckler rank. They all require certain things, and when you meet a requirment for a special rank, you MUST level up your current Swashbuckler rank into it, it does NOT happen automatically. These ranks are not only for show, but also a requirement for the Three Secrets. Also, if you have more than one special rank qualifed, it will randomly choose a rank to become when you level it up. That is unless your qualified for Vyse the Legend, then it will become that.Note: In case you didn't read, having a special rank is REQUIRED to unlock the Three Secrets unlockable.
