Demon bosses are encountered as part of the Demon Flash Mobs Distraction and Diversion. They serve as the main boss of the activity, although only one appears within each mob. It is protected by six imp heralds, four lesser demons and two black demons. Its name and, to some degree, its appearance is random, but the prefix and suffix of its name will affect its abilities.

Demon bosses are identified on the world map as Demon flash mobs map icon.png, an icon it shares with Elite Dungeons.

The demon boss will initially spawn at half of its life points, but will be unattackable until its lesser demons and black demons are destroyed. The demon boss will siphon life from these demons to recover lost health, hitting lesser demons for 3000 each hit (healing the same amount in the process) and hitting black demons for 6000 a hit. Players can slay the minions in order to minimise how much health the demon boss recovers and to attack the boss quicker.

Attempting to use prayers or curses, excluding Protect Item, while fighting the demon will cause it to deal higher damage with higher accuracy when hitting you. Using Blood spells will also heal the demon. Using protection prayers with Devotion will not reduce or prevent damage and will be ignored. The demon will also heal 10% of the damage it deals, rounded up.

Its attacks remove Resonance if launched when the ability is already active. If Resonance is activated after the demon boss attacks, it will not be negated and will heal from the attack normally.

Demon bosses spawn 15 minutes after a notification is given out on where their energy is building up. If the demon boss is not killed within an hour upon spawning, it will despawn, leaving players with no loot if it does so.

They are classified as greater demons; thus, killing them counts towards any greater demon Slayer task, and also allows a player to take advantage of the abilities of Slayer boosts.

Names[edit | edit source]

Prefixes[edit | edit source]

The boss of a demon flash mob will have a prefix to his name. This prefix determines the attacks the boss will use mainly, or what it is particularly good at.

Prefix title Effect
General Accurate melee attacks
Executioner High hitting attacks
Castellan Very high defence
Deacon User of magic

Suffixes[edit | edit source]

The boss of a demon flash mob will also have a suffix to his name. This suffix determines what special abilities this boss demon has. 

Suffix Effect
Blazing Burning damage over time (50 magic damage every 2 ticks without damage reduction), can be cleared using Freedom
Corrupting Poison area of effect (everyone within 3 squares of the boss is inflicted with poison that can deal over 1000 damage)
Frostborn Ice area of effect (everyone within 3 squares of the boss is stunned for three seconds)
Glorious Stun (lasts for three seconds at a time)
Infernal Fire area of effect (5 magic damage every 2 ticks without damage reduction), can be cleared with Freedom
Obscured Drains stats of nearby players
Pestilent Poison damage over time (extremely powerful poison, dealing from 600-1100 damage)
Rending Bleeding damage over time (50 melee damage every 2 ticks without damage reduction), can be cleared with Freedom
Shattering Melee attacks hit everyone within 3 squares of the boss
Terrifying Halves adrenaline gain of nearby players

Main names[edit | edit source]

A boss demon in a flash mob will have a main name, which can either be aligned to Zaros or Zamorak. This name doesn't have any further use.

Strategies[edit | edit source]

Main article: Demon boss/Strategies

Drops[edit | edit source]

In order to receive a drop, the player must deal at least 500 damage to the demon boss in a single hit. Once this condition is met, a notification will be given to the player stating that they have dealt a "powerful blow". The player must also stay in combat with the boss until it dies to be eligible for the rewards. If the player leaves or dies, the hit of 500 damage needs to be done again to still get a drop. Players will only be able to do this until the boss reaches 10% of its total health (40,000 life points); any attempts to initiate combat with a demon boss after this threshold will notify the player they are too late to be eligible for a reward from this fight.

A demon boss will always drop a minimum of five drops. A single player can receive five separate drops if they manage to defeat it alone. If two to four players defeat a demon, drops will be split amongst the top damage-dealing participants.

Demon slayer gear is dropped alongside any other drops that are received. For example, a player that receives an off-hand demon slayer crossbow will also get any of the other normal drops it gives.

Fighting a Flash Mob in the Wilderness gives you a greater chance of getting a demon slayer equipment drop, and other drops will be worth around three times as much as at other spawn locations. 

100% drop[edit | edit source]

  1. ^ Only dropped by Non-Wilderness version.
  2. ^ a b Only dropped by Wilderness version.
  3. ^ Acts as a normal drop, and is only given to the player that dealt the most damage.

Main drops[n 1][edit | edit source]

Demon bosses outside of the Wilderness have the following table for their main drops.

  1. ^ Estimated based on 925 kills from the RuneMetrics drop logging project.

  3. ^ a b c d e f g h The rate of this item is skewed. The actual drop rate might be higher.

Notes
  1. ^ These drop rates are calculated based on the average number dropped for demon bosses both inside and outside of the Wilderness.

Tertiary drops[edit | edit source]

  1. ^ Estimated based on 925 kills from the RuneMetrics drop logging project.
  2. ^ a b c d e f g This rate is based off of kills inside and outside of the Wilderness. Demon slayer equipment has a higher drop rate inside the Wilderness.
  3. ^ The specific title scrolls that can be given depend on the name of the demon boss. See #Demonic title scroll.

Demonic title scroll[edit | edit source]

Not to be confused with Kal'gerion battle commendation.

The name of the demon boss killed determines which demonic title scrolls it can drop. For example, a demon named "General Acidius the Blazing" can drop Demonic title scroll (general) and Demonic title scroll (blazing).

  1. ^ a b c d e f g h i j k l m n 1/1000 chance to get a title, with two titles available per demon boss.

Rare drop table[edit | edit source]

This monster has access to the rare drop table.
Luck-enhancing items are not required to access the table but they will increase the chance of accessing the rare drop table and may also improve the loot received from it.

Universal drops[edit | edit source]

Universal drops are dropped by nearly every monster outside of Daemonheim.
These items are dropped alongside main drops.

Achievements[edit | edit source]

Update history[edit | edit source]

The update history project is a work-in-progress – not all updates to this topic may be covered below. See here for how to help out!
  • patch 16 February 2015 (Update):
    • Demon Flash Mobs will now spawn hourly instead of every 2 hours.
    • Players will no longer receive rewards from a Demon Flash Mob boss if they join the fight especially late.
    • Demon Flash Mob bosses will now deal less damage to familiars.
  • update 2 February 2015 (Update):
    • Flash mob bosses' health and defence have been reduced.
    • Stuns applied by bosses' attacks now last only a third as long.
    • Healing applied to the bosses has been halved.
    • Bleed effects inflicted by demon flash mobs can now be cleared with the Freedom ability.
    • Bosses no longer cause bonus prayer damage against players using the Protect Item prayer.
    • Demon Flash Mobs now spawn every two hours, rather than hourly.

Trivia[edit | edit source]

  • On release, the demon boss would deal increased damage if any prayers/curses were being used. Due to player complaints about Wilderness spawns (at the time, skulls had been removed) which forced players to bring cheaper weapons or risk dying due to both the threat of player killers and the damage/accuracy of the boss, this was changed to allow the Protect Item prayer/curse to be used without any penalties.
  • The demon boss had 480,000 life points before they were lowered on 2 February 2015. It also had a Defence level of 132.
  • The demon boss has a total of 2080 possible names.
