X-Balls (エクスボール Ekusu Bōru) are a type of special medicine that allow Earth Land Mages to use their Magic in Edolas.[1]
Description[]
This Magic Item Is small red pills stored in a small bottle. They were used in Edolas by the Fairy Tail Mages. Once eaten, they enable the user to retain the ability of generating Magic Power, typically used by Earth Land Mages, even when travelling to a dimension with low magic levels like Edolas, where this isn't normally possible.[2]
