Beginner's Pirate Manual item

A guide for the cadets of the mysterious pirates that sailed away in search of an island with treasure. Only a thorough reader of this book is able to tell which one is the navigator among the many in identical uniforms. The rookies must have been under a lot of stress considering the circumstances where it was almost impossible to know who their superior was. This item will be consumed when you locate the target.

It comes out of Sea-soaked Pouch.
