Alright, so I've been running around as a tankhealer for a while, and I've just noticed this little quirk about the game that seems... off.
So a few hours back, I got my hands on a decent Oak Staff with Cure II available on it (I'm only still level 13, so yeah, I still run around with that kind of thing) - and it was great. Each use allowed me to heal for over 572 HP - so naturally I kept this Oak Staff and decided to upgrade it.
Upgrading went p well. I went with the Skill Evolution V artisan option, though, which meant that it'd increase the rank of whatever skill had the lowest rank on the weapon at the moment (Cure II) - which I thought was a good thing until I got Cure III.
Now, the skill details (in-game) DO inform us that Cure II has a base ratio of about 529, whereas Cure III has a base ratio of 788. When I tried this out, however, Cure III only heals for about 158 HP. I'm assuming that this was a mistake? Was Cure II supposed to heal that much, or is Cure III just munted?
