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 lifepoints, 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.
The demon boss can sometimes remove the player's
resonance before its attack hits.
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.

Fighting the pre-boss demons Edit
None of you will survive my wrath!
My minions will feast on your bones!
I will wear your flesh like a cloak!
You killed my heralds. Your nations will burn.
You will all fall before my minions!
Those were but my weakest followers.
Fools, the true fight begins now!
You dare meddle in my affairs? Kill them!
Demon boss finishing off its own minions Edit
My lord! I have returned!
Yes... I am reborn!
I will consume everything!
Demon boss Edit
More pain consumed!
Your destruction fuels my rage!
I will destroy you!
Your flesh is weak!
Blood! Blood heals me!
Is that all? I must have more!
More! Give me more!
Bow down, mortal!
Now to take my place!
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.
