Here's my conclusion given the provided info:right before the phase starts, n'zoth casts Конвергенция to merge his dimension & the chamber.at 84% of limit's attempt in mythic, magni yelled "champion's, n'zoth is breaching dimensions to assault the chamber of heart"and how do we skip dimensions to protect the chamber of heart?right!https://wow.zamimg.com/uploads/screenshots/normal/904017-dimensional-gateway.jpgthe heroic difficulty hinted at it being a thing. see https://i.gyazo.com/c8f1f58da0da77c777a86d987dfad068.pngso that thing has to be somewhere.once we get there, n'zoths eye will be covered in nightmare https://wow.zamimg.com/uploads/screenshots/normal/905241.jpgto clear the nightmare we get an extractionbutton (Маяк титанов) that is provided by picking up this object (Маяк титанов).before that, Протокол очищения will probably be initiated to summon the beacon at the countermeasure's locationand we have to avoid damaging it with Аннигиляция since we require the countermeasure's to spawn more beacons?
Oh yeah, time for my boy Magni to kick some mythic raiders' arrs
It's not uncommon to have a mythic or heroic only phase or boss, in firelands for instance, the last phase of Ragnaros is the true end of the raid.I don't think the end of nzoth in mythic will have another cinematic, but it will show us the true end other this arc.In previews expansions, the last raid always setup the next expansion "big problem":Pandaria: Garrosh corruption and the travel to old draenorDraenor: Archimonde throwing Guldan through the dark portal leading the legion to our world.Legion: Sargeras stabbing the sword on azeroth forcing the heroes to collect the planet power and leading the story to the nzoth release.With the shadowlands cinematic, maybe Sylvanas need us to defeat nzoth?In my opinion, if Sylvanas needs the power of the anima that souls represents in shadowlands, make no sense release nzoth to enslave and corrupt all living things on azeroth.It sound more like "let making them distracted solving this new problem until I'll start the new phase of my plan"Maybe the previous events like the magic used to open the screen Argus that leave a permanent red star on the sky and the sword weakening azeroth make the break of helm of domination possible?Sorry for the long text and the possible English errors :)
I See you...........
Well if this is the case he may actually go out in a proper fashion instead seemingly dieing with zero fight
