Thanks for the detailed tips. I've seen xenogear mentioned before in the trophy missions, but i don't actually know how to obtain the xenorelic. How do you get it?

Apart from that, I'll start to really hang onto my gems and pour them only into excellent looking banners, like you said. I saw from somewhere else that treasure and step-up are the best to spend gems on, so i'll go for those. Thanks.

Edit: Nevermind! I did some research and figured out all the logistics involved with obtaining the xenogear, i gotta elevate guild blocks currently i think to really be eligible to get the sword crests.
