When you're not tending to the crops and crafting new recipes, Rune Factory 5 will have you shoveling through a network of dungeons on a hunt for valuable loot. Beating them, of course, can net you some pretty nifty rewards, which you can then use to develop better gear for your farm. One of these rewards is the Crystal Skull, a rare drop obtained by defeating the Skull Dragon.
To reach the Skull Dragon, you will need to embark on a new quest to the Belpha Ruins dungeon. Upon completion, you will receive a bunch of items, one of which can be the Crystal Skull. Note that this particular item doesn't always drop, meaning you will need to rerun the dungeon several times until the item appears.
You can travel to the Belpha Ruins after triggering one of the main story quests. After speaking with Livia, you will be able to access the dungeon and search for the Skull Dragon. So, be sure to keep working your way through the story until you receive the right objective.
