"Deacon" redirects here. For the H.A.M. member, see H.A.M. Deacon.

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; the latter two it will devour to recover lost health. Its name and, to some degree, its appearance is random, but the prefix and suffix of its name will affect its abilities.

Attempting to use prayers while fighting the demon causes it to deal extra damage when hitting you.



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 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 six seconds)
Glorious Stun (lasts for six 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 nearby players and reduces adrenaline gain of all players fighting

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.

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.
