Dessous

Dessous, the Harvester of Blood is a vampire lord who must be killed during the Desert Treasure quest. The player is told of Dessous by Malak, one of the four guardians of the Diamonds of Azzanadra, who wants him dead in order to claim Dessous' land as his own. In order to achieve this, Malak tells the player that Dessous guards the diamond and if they wish to retrieve it they must eliminate him; it is when the player encounters Malak after the fight that he confesses that he is the real guardian and then gives the diamond to the player as a reward for his troubles.

Strategy
Dessous attacks with a combination Magic/Ranged attack (a swarm of bats) each of which does double 50s for a total of 100 life points. He mainly attacks with a much stronger and rapid melee attack (attack speed of 7, equivalent to a shortbow or throwing rings on rapid) which hits up to 190. Using either Protection from Magic or Ranged will stop half of the damage done by the bats. Players are advised to use Protect from Melee and to take armour which is resistant to magic attacks. Another option is using Protect from Magic and your best melee armour. A third option is to bring splitbark armour or dragonhide armour, as it protects from both melee and magic attack. If players try to hit Dessous from a long distance away, he will teleport closer to them, and if Dessous teleports three times in total he will get "bored of toying with you" and go back to his grave (this means you have to refill the silver pot and start the fight again). Melee attacks don't work well on him, so using powerful magic spells up close is a good strategy since he has a low magic defence. In particular, Dessous is commonly thought to be most weak to any of the air spells although earth spells work comparatively well. Another method that works well enough is to use fire blast and protect from melee to avoid his powerful melee attack; a decent player shouldn't need more than half an inventory of monkfish.

Because of his rapid attack speed, a Ring of recoil is particularly effective in this fight.

Dessous' magic/ranged attack has a loud, piercing cry when he uses it, so it could help to turn off the sound effects so it doesn't distract players when fighting him.

If any part of the quest is not followed correctly (for example, if the pot is not blessed), Dessous will say "You will never defeat me" when reduced to 0 life points and regenerate all his life points ready to fight again, so be careful!

Location
The site of the fight is Dessous's Tomb, which is found in the south-east of Mort Myre, in an area called the Graveyard. To awaken him, players must use a blessed silver pot containing blood, garlic and spice on his grave.

Trivia

 * Dessous' missile attack is similar to the Trick emote obtained from the 2008 Hallowe'en event.
 * Dessous in French means 'underneath', 'under' or 'below', perhaps pertaining to him being in a coffin.
 * In Recipe for Disaster, you fight Dessourt, who is a play on Dessous.
 * On many computers his bat attack's sound effect may cause intense lag due to its spammy nature, due to this it is recommended to turn sound off when fighting him.
