Crystal Berries are collectible items that can be found throughout Bugaria. There are 50 in total, and are used to trade for medals with Shades at the Underground Tavern.
If the Detector medal is equipped, it will alert Team Snakemouth when a Crystal Berry is nearby.
Collecting all 50 Crystal Berries rewards the "Crystal Collector" achievement.
