Description: After mining a Void Gem, Valencia gets cut from one of the void monsters. You and Valencia rush out of the cave as more void monsters start pouring into the cave. Valencia says that we definitely need some sort of potion or spell to help us traverse the Void safer. How about we try asking around Battleon to see if someone can help make one?
