Deprogramming is another of the new ICC weekly raid quests, and arguably the easiest. If this is your weekly quest, you will find the quest-giver atop the stairs just outside of Lady Deathwhisper’s room. The quest asks you to defeat Deathwhisper while keeping on the the adds, Darnavan, alive.
During phase 1 of the fight, Darnavan will spawn in place of one of the fanatics, usually during the first or second wave of adds. There are two main ways to deal with him. You can have a plate-wearing dps tank it in an out of the way spot, or you can have a druid keep it rooted for the duration of the fight. He seems to be immune to other forms of CC like sheep or traps. The add has a Bladestorm-type ability that will make him immune to roots temporarily, so watch out for that. He also has a fairly low health pool so he should be kept away from the raid, and out of any possible AOE effects, as much as possible.
Residue Rendezvous is another one of the new weekly ICC quests. If this is your weekly quest, you will find the quest giver in the upper reaches, just past the teleport. The description of the quest is a little misleading. Although it specifically mentions Professor Putricide, he isn’t involved in the quest. Instead, you must fight Festergut and Rotface.
To do this quest, you must get a special debuff from both bosses. You get Festergut’s debuff by having a spore explode on you, which is a normal part of the fight. You get Rotace’s debuff by taking a tick of slime spray damage. Each debuff lasts 30 minutes and will be removed if you die or get DI’d. To complete the quest, only one member of your raid actually needs to have both debuffs (but I’d suggest having as many people as possible get them to be safe). Just have everyone run back to the quest giver and the whole raid will get credit for it.
It’s a good idea to clear all the trash in the hallway between Festergut and Rotface’s rooms before you engage one of them to avoid wasting time and the possibility of accidental deaths. If one of the bosses is more troublesome for your raid group, make sure to tackle that one first, as wiping on the 2nd boss will make you fail your quest.
Of course, there are ways to cheat and complete this quest without actually killing the bosses, but what fun is that?
