I can confirm that she does in fact show up on the first playthrough. I am on shrine of amana now and she keeps following me into the cave with the poison mushroom bugs.

So apparently, if you pancake them with a greathammer, they stay down, as I've recently learned. You don't even have to kill them. They just lie there.

What is their dialogue when they chant? It sounds like they are saying something played backwards, similar to the Decons of the Deep who say “He’s going to kill me!” backwards when they see you and the crystal sage who says “Release me now!” Also backwards.

how can i get her armor set?

There's one that keeps walking around and she doesn't do anything, everytime i get close to her she walks away in a cute fashion.

everything fine until u read "More come out in NG+"

dammit i want their armor set :<

It sucks that you can’t get their armour. It looks incredible.

They don’t get back up from any overhead attack that ‘crushes’ them. For example, the strong two-handed attack on the Dragon’s Tooth, the Old Knight Hammer, the Large Club, etc. This means if you’re trying to run through the area and aren’t strong enough to one shot kill them, all you have to do is hit them with a single overhead crushing attack and then move on to the next one
