Thanks for the detailed responses! There are a few things I would like to clear up since I'm still fairly new.

-What are exceed weapons?
-I'm running fodla in the back, are more healers (such as gryla) really necessary? I feel like I have plenty of sustain and would benefit more from other abilities as of right now.
-What is a Phantom Grid?
-Is thunder f2p friendly enough, or should I consider trying to continue rerolling for another 120% edilon? I got quite lucky pulling 2ssr kamihime including Baal with Nid
