Skill Boosters are an essential tool to help you on your journey through Luna that allow you to upgrade you active skills up to a maximum level of 3, increasing their effects. These highly coveted items are in tight supply and cannot be duplicated by use of Lucky Events, and you'll need to find every single one to raise your skill mastery to 100% and get a shiny green star in your records tab.

I have formatted this guide in such a way to separate the skill boosters by area and leaving the shops for the very end, as such it will not be in the order you can first obtain them. This is to make it easier to sweep through the game to check every location once you've reached the endgame.

NOTE: Issues with the locations of some skill boosters were fixed as of version 1.1, as well as more skill boosters being added to facilitate the grind so you don't need to scour the entire world for missing a single booster. Locations 40 and 81-86 will be out of place numerically and just fit into their respective area.
