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.

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 minimize 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 can occasionally remove the effects of Resonance.

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.



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


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

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

  • You killed my heralds. Your nations will burn.
  • You will all fall before my minions!

Main article: Demon boss/Strategies


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. The player must also stay in combat with the boss until it dies to be eligible for the rewards. If the player gets out of combat by any means, they will lose the ability to get the drop from the demon, and must deal 500 damage in a single hit again to be eligible for a drop.

Fighting a demon boss in the Wilderness will give different drops and a drastically increased drop rate for the demon slayer equipment. Demon slayer equipment will always be included as a secondary drop, similar to clue scrolls and effigies.

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, leftover drops will go to participants.

  • 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.
