I finally got around to unwrapping my guide and flipping through it today. It's not bad. A lot of things are done right. A few strange choices, though.
I didn't see anywhere the explanation for the boss stats, though possibly I just missed it. If not... the "bonus" row is what's multiplied by Alex's level (not his HP, as it says in the beginning of the guide) and added to the numbers in the base row to get the actual stats. You can see this by inspection, but thought I should clarify; it took me a while to figure it out from the Japanese guide, which only lists the stats for the "expected" level.
The mini-boss guide for Mel in Meribia says that Alex should use Vigor, but I don't think the guide says anywhere that Alex should therefore be at Level 12 by the end of the Saline Slimer fight. I wonder if anyone will get messed up by that.
The same ludicrous height and weight -- well, weight; the heights aren't ludicrous -- stats are used as in the TSS guide. What's also used from the TSS guide is Alex's age of 15, which I'm pretty sure is wrong; he's older in the remakes. There are several other errors in the character profiles; Jessica's hometown is listed as Vane and Kyle's as Nanza, when both should be Meribia (where Kyle grew up, though not his current residence as of the time of the game). There's an obvious typo in Mia's stats chart. The stat charts themselves are great, though.
The guide also says that Dragon Healing removes status effects. I don't remember this; can anyone confirm, for this or previous games?
Sadrin: the Silver Darts you get from having the demo clear data are listed at the end of the Staves section of the weapon charts, inexplicably. They're also mentioned in the Secrets section on p. 220, since they can be purchased just before going to the Frontier, but (also inexplicably) they're described as "a great early-game weapon". The Frontier, of course, isn't early-game in any way. I would guess that they didn't want to put anything about the demo in the guidebook since presumably the demo will stop being available long before the game itself vanishes.
There's also the rather idiotic note before the Bromide section saying that while it may be a spoiler to show the bromides and their locations they can be pretty hard to get so we want to provide all the information. Then they show the bromides anyway, which is totally unnecessary to providing the instructions on how to get them.
It's strange that Mel isn't in with the bosses, just in the guide text itself. There's blank space on the bosses pages where his info could have fit. The statue isn't in those tables either.
The enemy charts are nice and comprehensive, but also lack a legend (that I could see) and need some things explained. The item drop % is out of 128, not out of 100, so it's not a percent
chance. The vulnerabilities to Alex and Kyle are to their spells, not their direct attacks. There are also other weaknesses and resistances that individual monsters have -- to various status effects and Jessica's Banish (Fear) Litany -- that are not listed. I suppose that's understandable since most players don't use status effects specifically much.
