Master Adventurer Trophy in Ginger: Beyond the Crystal
Complete all secondary missions in all the towns
How to unlock Master Adventurer
Secondary missions are short missions given to you by the locals in each hub world that are unlocked by completing the main story levels. They will be marked on your map by a yellow circle with an exclamation mark (!) in the centre.
These quests can be fetch quests, races, or involving defeating some enemies in a certain location. They are all very simple and straightforward. Once you have beaten the boss in an area you will teleported back to the Goddess' statue and when you return to the hub world who's boss you just defeated there will be a few more side missions unlocked you need to complete.
After you've done all of the side missions in an area, the trophy for that area will pop.
