me and some friends got destroyed by a Necrotic Wake 7, that necrosis or whatever Affix is a son of a bitch. We still finished it so it counts for the vault in a few days (213) so thats cool.
We then pissed on a Sanguine Deapth 6, so much so that I was shocked it didnt upgrade +2, it only gave us +1, but we had like 6 or 7mins left so that was a bummer.
Anyway the point of this little story is, as we were getting wrecked in the NW7, I started wondering how people do these higher keys (like the 10+ stuff) if 7 was already this hard, but then at the same time a short time later as we were crushing the SD6, I thought to myself "I guess just 1 week ago we were struggling with 6s" so in the end a bit of better gear on everyone really goes a long way.
7 is the point at which the third affix (Necrotic, this week) is introduced, so there's a significant difficulty bump between 6 and 7.
Necrotic Wake is also regularly considered one of the hardest dungeons in Shadowlands, particularly on Tyrannical when the second and third bosses can be major gear blockers (though the second boss got a
lot easier with the nerfs from a week or two ago).
As for dealing with Necrotic, you need to come up with a plan that fits your tank / group comp and be ready to deploy it on large pulls. Around 30 stacks, the tank should start determining whether they need to kite away, at which point the DPS should deploy slows, roots, stuns, knockbacks, and other control tools in order to give the tank the room they need to drop their stacks.
There are also lots of cheesy tactics that you can pull off. Phial of Serenity will clear it if your tank is Kyrian. Monk Ring of Peace works wonders for keeping your tank from getting hit. As a Paladin, I can hit 50+ stacks and then tap Divine Shield (with
Final Stand) to remove them all. :D It's definitely an affix that takes some practice though; it'll crush you if you don't pay attention to it.
So are these cinematics part of the Twisting Corridors? Still haven't even seen the first confrontation between the two yet in-game.
They're probably related to the weekly Bolvar quests that are being rolled out (which are supposed to connect to Twisting Corridors at some point, iirc). But yeah, both this cinematic and the one preceding it are only accessible from datamining at the moment; the story hasn't reached that point in-game yet.
