@Jethzki I don't think so, the undead thing usually is something like a curse, so the armor is taking the for she would have if she wasn't cursed, or maybe the author just wanted to show how her body would be if she wasn't a skeleton.
This is interesting, as he goes on in the dungeon instead of it getting harder as he goes on, it will get easier.
Also, if the armor fuses with flesh and blood our lady aint got any of that, so she is pretty much free to take it out whenever she wants.
I feel like this has a lot of Kenichi vibes, but in the case of Kenichi he was an actual martial artist learning martial arts the hard way, this guy is training specific things to confront specific situations without training anything else (exept endurance, that is useful no matter what).
This is too good, he prepared himself with profesional acting just to realize one fantasy of his. He also somehow always says bullshit that goes in par with the actual story, maybe he has something similar to an unconcious mental conection with the faith, so his imagination draws information...
