Blood reavers can be found in the Heart of Gielinor. They can be fought for killcount for the Zaros faction, counting as three kills each with 100% multiplier. These can be summoned by the player at any time in the dungeon, requiring 100 Ingression fragments, and granting 5 reputation. The reaver will proceed to attack nearby enemies and capture/defend nodes. Equipping a Zaros insignia makes them non aggressive.
