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. 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.

According to The Overseer, the Abyssal Sires are the engineers of the Abyss from a time before the God Wars. As their resources began to deplete and they had no means to escape, they constructed the Nexus and remained there in deep stasis.

It is known for dropping the Unsired, which is then used at the Font of Consumption behind The Overseer to get a chance of obtaining an abyssal whip, abyssal dagger, abyssal head, jar of miasma and untradeable parts of the abyssal bludgeon - the bludgeon axon, bludgeon claw, and bludgeon spine, as well as a very small chance at the Abyssal orphan.

Getting there

The Sire is located in the Abyssal Nexus, south of the Abyss used for Runecraft. It can be safely entered via the fairy ring code DIP (if the player has access to them), or it can be accessed via the Abyss although this drains the player's prayer points, and skulls them if not wearing an Abyssal bracelet. There are four chambers in the Nexus where Sire can be found, allowing multiple people to fight the Sire per world, similar to Cerberus.

Mechanics

Main article: Abyssal Sire/Strategies

As with all demons, the Sire is susceptible to the effects of demonbane weapons. Players in invalid tiles when a Sire is dormant will result in teleportation to the centre of the chamber. There is currently a bug causing deaths due to disconnection at Abyssal Sire to not provide a gravestone.

The fight consists of three phases:

• The first phase focuses on killing the Sire's four respiratory systems on the sides of the room that heal the Sire. This is easily done by using Shadow spells on the ancient spellbook to disorientate the Sire in order to take down the respiratory systems, or otherwise deal 75 damage to Sire with ranged or mage to do so.
• At the start of the second phase, the Sire gets off his throne to attack the player with melee. He may also summon Spawns and create highly poisonous miasma pools under the player. The Spawns are quite harmless at first, but they will mature into Scions after ten seconds who have more health and deal more damage.
• When the Sire reaches 50% health, he will walk to the middle of the room to initiate the third phase. Instead of attacking himself, he rapidly summons miasma pools, which the player should avoid. When the Sire reaches less than 33% health, it will teleport the player next to him and trigger a highly damaging area-of-effect attack, which can be avoided by running away as soon as the player is teleported. He will also summon many spawns to attack the player. After the player finishes the Sire off, any spawns and scions will die alongside him.

The Sire respawns near-instantaneously upon death.

Trivia

• The Sire has multiple examine options that can be seen throughout the fight (including its Respiratory systems).
• It is one of the few monsters that does not have a defensive animation; rather, it loops its idle animation instead.
• Despite being a solo-only boss, the Sire's area-of-effect attack at 33% health and poison fumes can harm other players if they are in range.
