It's a real tragedy that they didn't go and find all of the chests you need Schala's pendant for, at the soonest opportunity. I believe I did that once I had the flying Epoch. Though to be fair, the game doesn't force you to do that or make it clearly that such good elemental resist gear is out there, and I didn't remember the location of all of them and looked some of them up, because it's hard to remember all of them. Still, they really come in handy when the game throws obviously unfair elemental attacks at you.
Also it's just really unfortunate that they threw away those Ruby Vests from 65,000,000 BC almost immediately after buying them, because c'mon, even if the defense stat is terrible, you should clearly hold onto something that just flat-out always significantly reduces fire damage.
Also, gotta love that they don't really remember why their group might be banned from Guardia Castle in the present. No big deal, they just got sentenced to prison and then escaped and are fugitives.
