Demon flash mob fight

Players attempt to take on the mighty demons

Demon flash mobs or Demon raids are a members-only feature that was released on 28 January 2013. Flash mobs appear hourly in one of 14 locations including the Wilderness. Players with the required combat level get a filtered notice of a surge of demonic energy at a specific location fifteen minutes before the mob spawns, then receive a second message stating that the demons have spawned in that location. Mobs can spawn at any time.

This flash mob consists of a demon boss, two black demons, 4 lesser demons and 8 imp heralds. Once the minions are killed, the boss can be attacked. At the start, however, the lesser and black demons, as well as the demon boss, are invulnerable. To attack the lesser demons, all the imps must be killed. To attack the black demons the lesser demons must be killed. To attack the boss the black demons must be killed. The boss begins with 50% of his maximum lifepoints, that is, 240,000 out of 480,000. The boss regains his lost health by feeding from the life of his lesser demons, where he heals 3000. After the imp heralds or the lesser demons are slain, the boss will focus on his black demons, where he heals 6000 from them until they die.

Note that the demons are not aggressive. Therefore, one should look carefully for leftover demons. The next level of demons can be attacked when the boss himself says a quote. For example, when all the imp heralds are slain, the boss will say a quote, and then the lesser demons can be attacked. However, if the lesser demons are sent to battle and the boss drains the life from both of his black demons, he can be attacked, and the demons that he sent to battle can be left alone, although it is not recommended because the boss has very high lifepoints for his combat level.

Attacks vary depending on the region. Non-wilderness and Wilderness demons tend to focus on one person with melee or magic attacks depending on the player's distance. Non-wilderness demons can use multi-hitting magic attacks if there is a large amount of players at the site

The sign that a flash mob is arriving is an evil symbol on the ground. The evil symbol is where the boss will spawn. Right next to him will be his minions. 

The name of the boss is random. The titles before and after its name will hint at its abilities, as detailed below. This is how the name of the boss will always be shown: "(prefix) (name) the (suffix)", meaning a name such as "General Acidius the Glorious". According to the names shown below, this means this demon boss has very accurate melee attacks and can stun players. Demon bosses of all sorts will use melee and magic attacks. Their magic attacks are multi-targeting, and melee attacks are against one player.

Prayer of any sort is not recommended since doing so results in the boss dealing extremely deadly hits towards praying players, especially if the boss is an executioner type. Do not bring any item you can not afford to lose when the mob spawns in the Wilderness. One should be careful of the "Frostborn" type as this means players will be constantly stunned, even with the use of Freedom and Anticipate. It is also possible for a boss to kill aggressive familiars in one hit, so players should be careful of this.

Blood Magicks heal the demon boss, accompanied by a message from the demon discouraging its use.

A new mob spawns hourly; if the demon general is not slain by one hour after spawning, he will despawn, regardless of the damage dealt on him.



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 Multi-target magic attacks


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 title Effect
Blazing Fire-based damage over time effect (deals magic damage, similar to Combust, but cannot be removed by 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 nine seconds)
Glorious Stun (lasts for nine seconds at a time)
Infernal Fire area of effect (low damaging variant of Combust)
Obscured Drains stats of nearby players
Pestilent Poison damage over time (extremely powerful poison, dealing from 600-1100 damage)
Rending Bleeding damage over time (low damaging variant of Dismember)
Shattering Melee attacks hit everyone within 3 squares of the boss
Terrifying Binds players and reduces adrenaline gain

Main namesEdit

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. The Zarosian Demon's names shown below are Latin, which is a language used exclusively by Zarosians. The Zamorakian names are not in any known language.

See Distractions and Diversions Locations/Demon Flash Mob for all possible locations.

A new flash mob spawns every hour. The location is given in the chatbox 15 minutes in advance. A demon symbol is also visible on the world map. If the demon symbol is moving, then that means the boss is on the move, most often at full health if nobody has attacked.

Wilderness mobsEdit

Due to some drops being only available in the Wilderness and the increased value of drops, and due to the need to take good quality weapons and armour to fight the demon mobs, PKers and PKing clans are hunting players who are hunting demon mobs.

Within 2 days of release, some clans began targeting demon mob clans, infiltrating them in order to arrive at the flash mob and kill players once they received drops from the demons. Players may feel safe because some of the flash mob locations are within easy distance of the level 26 teleport boundary. However, stuns and teleblocks are often used to prevent players from escaping.

Players should be aware of the increased risk when deciding whether to hunt flash mobs in the Wilderness and what items to risk.

Also, because the demon boss hits extremely hard on players using prayers, the use of the Protect Item prayer is not recommended unless you want a quick death. This makes killing demon mobs in the Wilderness very dangerous. Therefore, you should take cheap weapons and food to avoid losing millions of coins.


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 leaves or dies, the hit of 500 damage needs to be done again to still get a drop. The drop will appear under the boss.

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

Demon slayer gear is dropped alongside the drop it was going to give you. For example, a player that receives an Off-hand demon slayer crossbow can also get any of the other normal drops it gives.

Strategy Edit

The following items are recommended for a player's inventory:

  • Do not use any prayers, as this will cause the demon's hits to become stronger.
  • Many high quality food items.
  • A one click teleport, such as a tablet, can be useful for getting away from the demon quickly. If the mob is gathering near Port Phasmatys and the Ectophial was used to get there, it can double as the escape teleport.
  • An anti-poison potion may be helpful if the demon has either the suffix Corrupting or Pestilent. Much better is to have one of the Poison Purge auras; activate the aura before the fight, and use a large amount of food to stay alive for a while. After some time, the poison begins to hit very rapidly and extremely high, but if using one of these auras, you can stay alive with absolutely no food once this happens.
  • If the mob gathers in the desert, take water skins or other source of water.

Trivia Edit

  • The evil symbol (Demon flash mobs map icon) that appears prior to the spawning of the mob has a striking similarity to the one that appears as a player casts Ariane's home teleport spell.
