How do you fix the action replay code for the guardian vocation on the UK dragon quest ix?

Answer 1

The 'guardian' vocation is the one your character starts with, and only exists for the intro section, before your character loses their wings and halo, and becomes Minstrel class.

There's no way to 'fix' it per se, because it is not broken. A character only holds that vocation for the intro, as above. If a hacking tool is used to change back to it, then problems will arise, the vocation hasn't been designed to be played for any further part of the game after that. It has no skills, no stat/level progression table, and an action replay simply can't add that in.
