Mythic: N'Zoth the Corruptor

I just beat him for the first time last night in a Pug. And I am just posting things here that I remember so I do not forget, and it can probably help others to try to beat him.

These are just mechanics I know that I was following that others were stating in the group that was in that I am putting into my own words.

I am assuming that everyone has their cloaks in the group. You need that cloak. My Cloak was a rank 6 one and I was fine.

1. If someone has a yellow ring around them, stand in it so it helps your sanity. It means that someone hit their necklace. It will help you. If you hit yours, don't move until the ring disappears, if you do move your ring will disappear. Don't worry if others stand in your ring, it helps them too.
2. If you know you are going to go insane and you already used your necklace, just jump off the side and die so others can continue the fight without having you attacking them.
3. If you are Tethered to another player, get close to each other (stand on each other) so you won't go insane. By Tethered to someone I mean being Linked to another player by a beam.
4. To go down in phase 2 you will see a DARK BLUE Puddle that forms somewhere and depending on the group going down, go in.
5. When you go down, Kill the Big Guy that is running around.
6. To get back up after killing the Big Guy go and click on your spirit that is exactly where you went down to begin with. It's like a yellow orange color.

Aside from that, just kill.

I have never gotten him down before and for a very long time have tried to kill him with other PUG's. This time I got it down. I was on my Warlock on Mythic.

People just don't know what they are doing for mechanics. I hope this all helps.
Anyone wanting to add anything else please do.
