This event is more or less a carbon copy of the last one. Expect to farm the same amount of materials as the last one over the course of the week. As for myself, I'll do exactly what I did then and hope for the same result.
WTF? :P I did not notice at all. I hope it's buffing the right element... I wonder if this is some sorta translation mistake because it's an event Eidolon and the last even Eidolon was Dark/Fire?
*edit* Seems to happen after limit break? My fresh Phoenix shows Light/Thunder
I think I'll dub the dark/fire glitched phoenix Jean Grey
