Ripper Demon

Ripper Demons are Slayer monsters that can be found in a cave under the Abbey of St. Elspeth Citharede. They require level 96 Slayer to be killed.

According to the miner journals and the diary of Jebediah Omnis, a prospector named Jebediah Omnis hired a group of miners to excavate a new mine underneath the Abbey. The miners reluctantly agreed, finding no ore in the process. One night, when they tried to leave the mine they found that the entrance had mysteriously disappeared. Over the course several days they spent trapped in the mine, the remains of the previous Ripper started to latch onto them, painfully warping their bodies and turning each individual into ripper demons, themselves. The head of the mining excavation, Jebediah Omnis, turned out to be behind it all, turning himself into a ripper demon, as well, for he was a vengeful Zarosian zealot, wanting to please his lord in reviving the legend of The Ripper.

Location
Ripper Demons can be found in an abandoned mine under the Abbey of St. Elspeth Citharede. To access the mine, climb down the steps near to the Abbey, east of Al Kharid's east gate. Even though the area can be entered through the Kharidian Desert, the steps on the path to the Abbey are faster.

Mechanics
It is highly advised to use Protect/Deflect Melee when fighting Ripper Demons, as their attacks are extremely fast and can frequently attack three times in one go. If the player tries attacking them from a distance, they will teleport to the player and use Slaughter on them. As the mine is extremely cramped, multi-targeting abilities are not recommended as it will cause more demons to attack you.

Like a few monsters, the demons make use of the adrenaline system, gaining adrenaline as they attack. If the player's health drops below 50% of their lifepoints, other nearby Ripper Demons will attack the player as well once they leave combat. Keep health above 50% as you kill a demon or as it uses its special to prevent them from piling you.

The most dangerous ability Ripper Demons have is when they teleport into the shadows. A shadow will be seen at a random location near the player, and must be avoided. If the player is next to or directly on the shadow when the demon comes down, they will be instantly killed. It is better to run away from the shadow rather than using Surge or Escape due to the small area they reside in. This ability can be used any time after their adrenaline is filled. Their adrenaline bar will not appear for a while after this ability is used, so the demon should be killed quickly when this occurs. Playing on lower graphics will help avoid this ability as on higher graphics, the ground can be just as dark as the shadow, making it harder to avoid.

When a demon is defeated, they will start attacking wildly around them, dealing 950 melee damage per tick to nearby players before dying. Simply run away from the area when it is about to die. Devotion will not block the hits from this attack.

Trivia

 * Even though they are demons, they don't explode, similar to imps and tormented demons.
 * There is a glitch where if a Pack yak is brought and the demon uses its instant-kill ability, when it lands down a game message will say "This familiar will only attack in self-defence.", even though the demon is not targeting the yak.
