Blessed Weapon (5e Equipment)
From D&D Wiki
Weapon (any melee weapon), rare (requires attunement by a paladin)
This weapon has been blessed, perhaps by the deity to which its user swears their oath.
The weapon has one charge. Its user can expend the charge as part of a Divine Smite to immediately recover the spell slot consumed by the smite.
The weapon regains its charge when its user completes a Short or Long Rest.
