Do out of party members gain any XP?
Specifically, in Chapter 7:
Nia turns into a Blade.
So, when that member is out of the party, do they still get XP like a normal party member (since out of party members do get XP on discovering new locations).
Solution 1:
Yes, that party member does appear to get discovery exp. It took a while to discover a bunch of areas to test, but that member does indeed still gain exp.
