Now that I have a nice shiny opening post, let's get down to some business.
Firstly: 退魔の力
The wiki calls this exorcism power, while the translations I got for the items calls this Antimagic. I'm unsure of the exact game play effects it has, but the all damage reducing item states that it doesn't reduce Antimagic damage. So I assume it's defense piercing power. I think Antimagic gets the point across more, but maybe there is a better translation, ideas?
Also 魔. Magic or Mystic? The majority of the files have it as Magic, but it may be confused with magic in general. Items typically have all their elements listed though, so it might not be a huge deal. It's just something we should nail down.
Next, 行動制限 is best as impair (covers Blind, Silence and Confusion) and 行動不能 as disable (Paralyze, Petrify and Sleep). There were some various inconsistencies with the naming of these status groups I had to fix, may of missed some as well.
Edit:I can get all the English we have back in, but since the skills aren't translated they become gibberish. So the game isn't really playable as the wiki can't be used to reference the skills anymore. No patch for now then.
