Abyssal Demon OSRS Guide [2021]: Battling the denizen of the abyss

If you have advanced high enough in the Slayer Skill, you will be putting yourself in the crosshairs of some very difficult denizens of the abyss. One of them is the Abyssal Demon, and they are one of the strongest demons and also not a slouch in the boss fight department either. Despite this, these massive monsters also offer some of the best loot in the game, so it’s important to know how to fight them.

Abyssal demons have a moveset, attacks, and skills that can be overwhelming to inexperienced Slayers, but if you can defeat them in combat you will be rewarded. That’s what this guide is for, where we will break down the abyssal demon and its variants to give you the best chance at defeating them.

What Is An Abyssal Demon?

They are one of the strongest types of demons you can find in the abyss. They have average speed and a low max hit of 8 points, but their high accuracy and ability to teleport around the battlefield can easily wear a Slayer down. Plus, these strong demons can attack you in larger numbers as well.

Abyssal demons have a combat level of 124 and are 1×1 tiles in size. Their main move is to teleport both themselves and the player around the battlefield. They will teleport around you, and when they do trigger this move, you automatically stop attacking them. Then you will need to react to their positioning and start attacking them again.

You will need to deal with them in melee, as their teleporting abilities allow them to close any gaps between you and them and that makes safe spotting impossible. Auto-Realitate is also another great option to have to help counter the demon’s teleporting abilities. This mode allows you to automatically defend yourself from attackers rather than having to click on them yourself.

Greater Abyssal Demons

These rarer demons are greater versions of the abyssal demons, and they have more health and do more damage. If you are fighting regular abyssal demons and have unlocked the ‘bigger and badder’ reward they have a chance to spawn. Aside from having more health and damage, and dropping more loot when defeated, they are fought using the same tactics as the regular abyssal demons.

They also have a specially, 100% accurate, unblockable attack where they teleport around the player and make attacks four times. The blows hit for a guaranteed 20 damage for each hit, so if you don’t want that wittingly down your health, you can keep protect from melee active and weather the storm before fighting back.

Where Can I Find Abyssal Demons?

You will be able to find these demons in the Catacombs of Kourend and the Morytania Slayer Tower. The Catacombs are crawling with Abyssal demons and other monsters, so having a prayer-based setup works well here. Using items such as the Slayer Helmet, the fire cape, peaceful blessing, and a berserker ring are some items that will aid your survivability. Additionally, the Abyssal demons are vulnerable to demon bane weapons and are not immune to poison or venom. Finally, the arclight gives bonuses to battling abyssal demons, so make sure to bring that.

You also will need strength, prayer, and super attack potions, along with teleports to house and a herb sack. For prayers look for prayers that protect you against melee attacks and prayers that preserve you.

Once you are prepared, you can head to the Catacombs of Kourend by walking or by using the Kourend teleport. Head north into the catacombs, fighting or avoiding all the other monsters there. Once you head to the northernmost area, you will be swimming in Abyssal Demons. Turn quick prayers on, use your potions, and be mindful of their teleport.

Finding Abyssal Demons In Morytania Slayer Tower

The second location you can find these demons is the Mortyania Slayer Tower, easily accessible by using a Slayer Ring. You can slay the abyssal demons up on the top floor at any time, but the basement can only be accessed if you are on a slayer task. A Slayer helm is perfect for the top floor combat as the other floors are infested with aberrant specters and they can prove to be a challenge.

Same thing in the basement, where you will need to clash with some gargoyles and then head to the bottom floor to fight the demons. The equipment loadout for the tower isn’t that different from the catacombs, so if you can handle the abyssal demons in one location you can handle them in another. The same thing goes for the inventory, however, you might want to bring along Giuthan’s set which will allow you to carry more manta rays as food. More food equals more healing and more time in the tower.

What Do Abyssal Demons Drop?

Abyssal Demons Drop

Slaying monsters for the XP and also to protect the innocent denizens of the world from them is all noble, but most adventurers slay monsters for the loot. The Abyssal Demons and their boss variant are the only creatures in the game to drop the abyssal dagger and the abyssal whip, easily some of the most powerful weapons in the game.

The abyssal dagger requires 70 attack to wield and it comes with a +5 attack bonus and +3 strength bonus. It also has the ‘Abyssal Puncture’ special attack which hits twice and has extra accuracy but reduced damage. It can either hit or miss with it’s single attack roll.

The abyssal whip is a melee weapon that is capable of attacking at the same speed of daggers and scimitars. While you can’t train strength with it, you can do a lot of damage really quickly with the weapon. The special attack, energy drain, increases accuracy by 25%. If you use the whip in PVP mode, you will receive 10% of the hit player’s energy.

The whip also has three upgradable options. The first is an abyssal tentacle, where a kraken tentacle can be attached to the abyssal whip. This gives you more attack and damage, but also consumes the whip. Once the whip uses all of its 10,000 charges, then you just get the kraken tentacle back.

Volcanic or frozen whip mix can allow you to create the frozen abyssal whip or the volcanic abyssal whip, which are both purely cosmetic. No additional damage is done if you have either of these whips equipped, and you can get the regular abyssal whip back by applying a cleaning cloth to the whip.

Magic Items

The abyssal demons also drop a few magical weapons as well, like the magical orb and the abyssal wand. You need to have these demons as your slayer assignment, but both objects can cast Slayer dart and can also save runes. Slayer dart is very useful because it is the only magical combat spell that can damage a Turoth or a Kurask.

Using Abyssal Demons To Train

Using Abyssal Demons To Train

These demons give a lot of experience to players, and if you can find a way to slay them quickly and efficiently, then you can get a lot of XP and a ton of crimson charms per hour. You should use area of effect attacks and equipment for both melee and ranged weapons because it will help you survive should the demons swarm you with teleportation attacks. Demon Slayer equipment is the best option for protection for all the buffs and extra damage it gives against demons.

You can also use an attuned ectoplasmator and a demon horn necklace to get unlimited prayer points and remove the need for so many super restore points. A gem bag can also be useful as the demons tend to drop uncut rubies and uncut diamonds as common loot.

Taking On The Abyssal Sire

The abyssal demon does have a boss variant just like some of the other creatures, and that variant is the Abyssal Sire. You will need an abyssal demon or Abyssal Sire slayer task and will need to be slayer level 85. Now, you can find the Abyssal Sire inside the Abyssal Nexus. There are four chambers inside of which a Sire can be found, you just need to enter one and you are ready to go.

The boss fight has three phases, and it’s certainly not something you want to take on if you are unprepared. The 1st phase has four respiratory systems that continually heal the Sire, and you will need to disorient the Sire before destroying each of the four systems. Once that is done the Sire will enter the fray and attack you, also summoning spawns and creating poisonous pools to overcome the player’s mobility.

The spawns will need to be slain early, as they turn into upgraded Scions if left alone for 10 seconds. When you manage to whittle down the Sire down to 50% health, then he will retreat to the middle of the room and summon more misma pools. As you batter him down to 33% health, it will teleport the player next to him and launch a damaging AoE attack that you will need to avoid. He’ll also keep summoning spawns.

After the Sire is killed after this grueling battle, all the summons will vanish and you will have won. It’s a tough fight, but you can keep coming back to one of the four locations to grind and try to get some of the rare gear it can drop. The various unsired drops can be turned into rare items at the font of consumption.

For this fight, you want to bring your best gear. A Slayer Helmet, Necklace of Anguish, Armadyl chestplate, Barrows Gloves, and lots of prayer potions, demon bane weapons, and runes. Additionally, focus on melee, as ranged is only used during the first phase of the boss fight to damage the respiratory systems. Other than that, melee damage is going to be the key to your survival.

Abyssal Demon FAQs

Question: Do I Need Slayer Tasks To Kill Abyssal Demons?

Answer: In order to access certain locations, you will need a Slayer task. For example, being able to hunt down the demons in Kuradal’s Dungeon requires you to have a task from Kuradal, Morvran, or Laniakia. Then you can go into the dungeon and fight the 10 abyssal demons there. Inside the Slayer tower, you can kill the abyssal demons on the top floor at any time, but the basement will be locked behind a Slayer Task.

Question: Should I Kill Them In The Wilderness?

Answer: Along with being in dungeons and the abyss, you can also find a group of Abyssal Demons in the Graveyard of Shadows in the level 17-19 wilderness. You can gain extra experience for killing abyssal demons here if you use a demonic skull and have accepted the special slayer contract from Erskine. That’s 40% extra experience for every demon you kill, which is nothing at all to sneeze at.

Keep in mind though, that the wilderness abyssal demons will have access to the wilderness loot table, and will share that with their own loot table. You probably don’t want to farm abyssal demons in the wilderness if you are hunting for those rare drops. Still, the extra XP can make hunting the wilderness demons lucrative, especially if you are grinding for those last few levels.

Question: Should I Farm The Sire?

Answer: The Abyssal Sire boss not only spawns in four rooms in the abyssal dungeon, but it also respawns once it is slain. If you are prepared to handle the tough and multiphase boss fight several times over, it is possible to farm the Abyssal Sire for experience points and the Unsired items, which can be turned into better gear and weapons. These items can include parts of the abyssal bludgeon and even the very rare abyssal orphan.

Keep in mind that you will need to endure the boss fight, and also have an active abyssal demon or Abyssal Sire task to kill the Sire in the first place.
