'Pure white oath-cloth given by Varré. The final trial to be anointed a Knight of Mohg, Lord of Blood. Soak the cloth with a maiden's blood... The blood of anyone's maiden will do. You are maidenless, after all.' The Bloody Fingers are the canon's most explicit hostile-Tarnished covenant: an order of invading assassins given over to Mohg, Lord of Blood, recruited at the Rose Church and a Site of Grace. Varré, the unsubtle priest of Rose Church, runs the recruitment; the Festering Bloody Finger is the consumable that lets a Bloody Finger invade other players' worlds in real-time multiplayer. Lore and mechanic align: the Bloody Fingers are PvP given a religion.

'Her legacy is stained by accursed blood.' Eleonora the Violet, Nerijus, the Ravenmount Assassin: these are the canon-named Bloody Fingers, each met as a hostile invader by the Tarnished's own agency. Yura, the Bloody Finger Hunter, is the ally who tracks them down. Their souls may be offerings to the Formless Mother whom Mohg worships. Mohg's intention with the order was to build a private army of grief-poisoned lord-candidates; the order grew faster than he could control because the Lands Between has more grief-poisoned Tarnished than any one demigod can use. Many a Bloody Finger keeps invading, after Mohg is dead, with no remaining patron and no idea their religion has run out of god.
