@CountryMage He had to use 'Heal' on the skill book, though. 'Shield' is probably on the unlock path of his 'Priest' class, if there even is such a thing. For all we know,
all skills/spells come from books. Maybe there are
no innate unlocks from merely gaining levels.
My point is, MC knows
nothing about
any of the systems in this world. He doesn't know stat gains, he doesn't know skill acquisition, he doesn't even know the world's common sense for crying out loud! Betting on
possibly getting some anti-debuff skill/spell because
that's what most healer classes in games have is plain moronic. He's so focused on "oh, this is how my games worked", that he fails to consider that maybe
this world is nothing like his games. Because of that he's not even
trying to learn how it all
really works.
