Just adding on a little bit~
emotion_c8 You know that lovely quest Deva gives you to go find Kamila? Well, basically, when you're finally finished that, you're almost attuned.
You first look in the yellow maze, which is the first section of caves (noted by the yellow lanterns blazing within). Eventually, you'll hit green room/maze, the second section of caves (name because of it's green lanterns). Here, the monsters are a lot tougher, most being 12.0+, so being 11.5CL or higher means you'll have a better chance at living! Finally, after travelling through GR, you'll hit HPR (Hundred Percent Room), where everything gets a lot bigger. (You avi isn't a tiny dot anymore)
In HPR, there are 3 counts, which you defeat one at a time. During the third count, you'll see Kamila watching you, but she won't start her dialogue until after you kill the count. (Make sure you're alive when it dies, or your quest will not progress!) Then she gives you this nice speech about wanting to rule zOMG and how she's building up her army and stuff. *SPOIlERS*
Once she leaves, head back to Deva and talk to her. She'll send you to Alastor, who asks that you kill 100 minions. Once you complete this assignment, you're now attuned and can use the domo door at anytime to go straight to GR!
BTW: This is what HPR looks like:
And here's good ol' Kam at the end:
