Sacred Treasure

Sacred Treasures are uniquely powerful weapons wielded by the Seven Deadly Sins and were once treasures of the Kingdom of Liones.

Background
Not much is known of the Sacred Treasures but according to King, King Liones entrusted these weapons to the Seven Deadly Sins when the king of Liones formed them.

After the Seven Deadly Sin's betrayal, some of the Sacred Treasures were lost to fate: Meliodas sold his dagger to fund his Boar Hat business; Ban's rapier was stolen after he intentionally lets himself get captured by the Weird Fangs 5 years ago and Diane lost Gideon for unknown reasons until she later regained it at Byzel. King and Gowther remained in possession of Spirit Spear Chastiefol and Twin-Bow Herritt.

Description
According to King, a Sacred Treasure grants the user to draw out their power to its full potential. He exemplifies the strength by using the lake and a cup as an comparison for his use of Chastiefol in combat. As Helbram stated that the Sacred Treasures made the Seven Deadly Sins the most formidable group of knights that could suprass even the Holy Knights. Sacred Treasures cannot be picked up and used by anyone but the Sins themselves, although Helbram was able to hold Chastiefol with ease when battling King at Byzel.
