Abyssal Sire
The Abyssal Sire is an abyssal demon slayer boss that requires level 85 Slayer to kill. To access the boss, the player must have visited the Abyss at least once, either through the Mage of Zamorak or the fairy ring network.[1] As with all other slayer bosses, the Sire can only be fought when assigned abyssal demons or itself as an assignment. Although it resides in a multi-combat area, it is a solo-only boss.
