Quarterstaff of Mercy (5e Equipment)

Weapon (quarterstaff), uncommon (minor) (requires attunement)

A quarterstaff tipped with a blunt iron awl.

Blow of Mercy. When this staff delivers a blow that would reduce a creature's hit point to 0 or fewer, you can give the creature a merciful end, feeling no pain, and the scars they collected in the battle that led to this no longer hurt, only feeling calm as the creature takes it last breath.
