The Abyssal Sire is a level 85 Slayer boss that can only be killed when assigned Abyssal demons or the Sire itself.

It is mainly killed for its unsired drops, which can be used at the Font of Consumption to obtain valuable rewards such as the Abyssal dagger, the Abyssal orphan or parts of the Abyssal bludgeon.

Suggested EquipmentEdit


Melee is only used for the second and final phase of the fight.


  • 4-5 Stamina potions (depending on how long you last)
  • 8-12 Prayer potions or Super restores
  • 1 Sanfew serum (in the event that you get poisoned)
  • 1 Super combat potion
  • Magic/Ranged weapon to deal with the respiratory systems
    • If bringing a ranged weapon, consider taking a ranged body and Ava's accumulator.

If it is your first time at the Sire, you may want to bring less stamina, prayer/super restore potions and replace it with food instead.

How to get thereEdit

The Abyssal Sire is located in the Abyssal Nexus, which is found in the Abyss. To get there, players will either need to use the Mage of Zamorak who is found near the Southern Wilderness mining site. Using this method will require completion of Enter the Abyss. This method is not recommended as you will become an easy target for any potential PK'ers and unless using an Abyssal bracelet, will be skulled upon entering. You will also lose all prayer points if entering this way. If you enter through the Mage of Zamorak, you will need to head to the south central section of the Abyss to reach the Abyssal Nexus.

The far safer way to access is through use of the Fairy Ring network. You will need to have access to the Fairy Rings, which is accessed after partial completion of Fairytale II - Cure a Queen. Use the code DIP and you will be sent straight to the Abyssal Nexus without being skulled and losing all of your prayer points.

There are four Sires in each world, in the northeast, northwest, southeast and southwestern areas of the Nexus. There are four eyes near the Font of Consumption; interacting with them will tell you if there is another player in that chamber.

Attacks & AbilitiesEdit

  • Melee attack: Only used during phase 2 of the fight. There are three different types of melee attacks which affect the damage the Sire does. Even though the Sire can hit through protection prayers, it is still advised to use Protect from Melee as it will greatly reduce damage.
    • Swipe: The Sire swipes its right arm at the player, dealing 2-6 damage through prayer.
    • Back swipe (1x): The Sire uses one the tendrils in its back to swipe at the player, dealing slightly more damage than an arm swipe.
    • Back swipe (2x): The Sire uses both tendrils in its back to swipe at the player, dealing up to 26 damage through prayer. This is the hardest hitting melee attack the Sire can use.
  • Tentacles: Six tentacles are in each Sire chamber, guarding the respiratory systems. They are only active during phases 1 and 3 of the fight, and attack with typeless crush, which can deal up to 30 damage.
  • Spawns: The Sire is capable of summoning spawns to assist it in battle. During phases 1 and 2, the Sire will occasionally launch a spawn out from its mouth, which will land around the player's location. The spawn is aggressive, has 15 hitpoints, and uses inaccurate melee/ranged attacks. If it is not killed in 10 seconds, it will mature into a scion, which is stronger, more accurate and can hit through protection prayers.
  • Portal: This attack only occurs during the last phase. When the Sire reaches 139 hitpoints or lower, it will forcibly teleport the player next to it. It will then explode for up to 72 damage if the player does not get far enough and continually summons up to 10-14 spawns until it dies.

Fight OverviewEdit

Sire poisonous fumes

The poisonous fumes that players must avoid.

The Sire is a solo-only boss, despite being in a multi-combat area. This means that other players cannot assist in the fight (although they can drop supplies if you want). The Sire and the spawn/scions will only attack the challenger; they cannot attack other players nor can players attack them. However, poison fumes and exploding portals can damage other players if they are too close to them.

All of the chambers are identical to each other; the only difference they have is the path to the chambers.

Note: When killing the Sire, make sure that Auto Retaliate is off.

Phase 1Edit

Sire in stasis

The Abyssal Sire in stasis.

The fight begins when the player attacks the sleeping Sire. The Sire and the tentacles will awaken and the battle will begin. The Sire only uses poison fumes and spawn launching against the player during this phase. In order to progress to the next phase, the four respiratory systems in the room must be destroyed. Attacking the respiratory systems head on while the tentacles are awake is not recommended, as they greatly reduce the damage dealt to it and can also deal a lot of damage.

Disorienting the Sire:

When disoriented, the Sire and the tentacles will be stunned. When the tentacles start to wake, run back to the Sire and cast a shadow spell until it is disoriented. If you are casting anything below Shadow Barrage, you may need to use multiple shadow spells to disorient it. The respiratory systems can only be attacked with either Magic or Ranged; a Toxic blowpipe is recommended to destroy them quickly. When done efficiently, the Sire only needs to be disoriented twice to move to the next phase.

Phase 2Edit

Note: At this point, the player must kill the Sire or the whole fight will be reset. The Sire will return into the chamber if it is not attacked for one minute. If the first attacker dies/leaves, another player can attack after 10-20 seconds have passed.

The Sire will leave its resting place and will attack the player with melee. Use Protect from Melee; although the Sire can hit through protection prayers, it has less accuracy and does lower damage when it is active. The Sire can still summon spawns and launch poisonous fumes during this phase. If any scions persisted on phase 1, trap the Sire and let the scion die off before attacking to mitigate damage.

During this phase, all six tentacles in the chamber will be disabled, so they will be unable to damage the player during this part of the fight. If you try to safespot the Sire, it will forcibly teleport you next to it.

Once the Sire is damaged to below half hitpoints, phase 3 will begin. Switch back to Protect from Missiles during the phase transition animation. Note that any attacks dealt to the Sire when it is below 200 hitpoints will deal no damage to it.

Abyssal Sire phase 3

The Sire opens a large portal within its body, causing spawns to emerge until it dies.

Phase 3Edit

Stage IEdit

The Sire walks to the middle of the area, and will stop attacking with melee. As soon as it finishes attaching itself to the ground, four spawns will appear. It will only throw out poisonous fumes as its only attack at this stage. In addition, the Sire gets increased hitpoint regeneration during this stage, often healing 3-6 lifepoints every 2.4 ticks. The tentacles will also awake again, though they can still be easily avoided.

The poisonous fumes can be easily avoided by moving back and forth. Select two tiles that are within melee range (make sure they're out of the reach of the tentacles), attacking the Sire in a 1-2 format. Keep repeating this until you fall low on health or the Sire falls below 140 hitpoints. If you do fall low on health, safespot the scions and cast blood spells until they are all dead. This way, you will be able to damage the Sire during this stage without having to worry about them.

Once the Sire reaches 139 hitpoints or lower, stage two begins.

Stage IIEdit

As soon as the Sire falls reaches 139 hitpoints or lower, the next attack the player does will teleport the player south of the Sire. This attack doesn't deal any damage (as with all phase transitions). The Sire will explode 2 ticks after teleporting the player, dealing massive damage if you don't move away in time. Simply run a few tiles south and run back up once it finishes. Up to 14 spawns will appear after this move is finished, either spawning under the Sire or popping around the chamber.

Be aware that the Sire will follow up the explosion with three more poisonous fume attacks; after that, it will occasionally send one fume at a time (although it can stack up to 3 fumes). Keep attacking the Sire, going under and behind it so the summoned scions will take slightly longer to reach you. Players with a dragon or crystal halberd can use the special to quickly kill the Sire before the summoned spawns turn into scions.

If you need to heal yourself, lure the spawns/scions while casting Blood Burst/Blood Barrage; their negative magic defence should ensure that your spells will hit and heal a large portion of your health, even if you have a negative magic bonus. This should be done when the player is near the southwestern area of the chamber, as there is a spot where you can safely cast blood spells on the minions. When finished, run back up to the Sire, attack it once from the front, then move back and attack twice so that the minions will take longer to catch up to you; be wary of any poisonous fumes that appear while you do this. Keep attacking the Sire until it dies, or you feel that you need to restore your health again if the scions deal too much damage to you.
