History
Lostvayne was entrusted to Meliodas by King Bartra, and was in Meliodas' possession until 10 years ago when he sold it in order to raise money to open the Boar Hat. Merlin later bought it from a pawn shop in Camelot and kept hold of it until she returned it to Meliodas during Albion's attack on Camelot.

Abilities

 * The sacred treasure Lostvayne's special ability that allows Meliodas to create up to four clones of himself. The clones only retain a fraction of the original's power, with one clone having half the power level of the original. The halved power level is divided among each additional clone. Each Physical Clone is still able to use Full Counter to its full potential as the attack focuses on the enemy's attack power rather than the one using Full Counter, this allows Meliodas to use Full Counter multiple times on the same attack. Depending on the enemy and Meliodas's power level, it is additionally possible for him to use his clones to fight the enemy, dealing and taking damage without Meliodas himself getting involved in the fray.
