Crystals

[Cilia]

The crystals do seem to be tied to your blessing, as they appear in your mindscape after getting each one and after Middy strips your blessing that mindscape seems to fall apart. Anyway, you get them in order as follows:

Water - Lv5(ish) starting city quest.
Fire - Defeat Ifrit.
Lightning - Rescue Frixio from the Thousand Maws of Toto-Rak.
Earth - Defeat Titan.
Ice - Defeat Isgebind.
Wind - Defeat Garuda(?).

EDIT: Yep, the Wind Crystal is the last one you get, after some kind of feedback from the Echo forces it out of Garuda when she tries to temper you.

Which is weird, because Ifrit tried to temper us, and that didn't happen to him. His was a big wave of fire, and Garuda's was much more of a targeted tornado on us, so perhaps it has something to do with that?

I'd like to think so; Ifrit's wave was for a group of people, so there was probably less effort put into it, leading to a weaker reaction. Since Garuda specifically targeted you, she was likely putting more effort into it, leading to the feedback phenomenon from the Echo.

We know it takes some amount of effort to temper mortals based on the Company of Heroes' strategy for besting Primals, so it's not out of the question.

I don't think it was feedback, as such. We're told at the beginning of the game that our deeds will cause the Crystals to reveal themselves to us; I posit that's what happens here. Our standing against Garuda calls the Crystal of Wind to us.
