Wow you're actually playing that hack! Even I haven't played it all the way through
Not even the "normal" version. I really made it to prove that I could completely change a character's sprite, that and I liked Golbez's 24x16 sprite and wanted to try out a completed version of it.
Uh oh, now I'm scared.

I'm not totally sure why I gave Tellah "Pray" either...LOL. I do typically use Yang's guard to fill in for most character's empty spot if they have one. I mean it's a semi-useful command and, well, there are 5 slots. I am trying more interesting stuff now though, like Cain's commands change each time he returns, he gradually acquires Yang's commands each time he defects and returns. For example he starts off with "Jump and Guard", then after Zot he has "Jump, Guard, Kick", and then after Bab-il he has "Jump, Kick, Focus/Gird". I guess I figured out a form of "Decant Ability" before Tokita and his minions built it for 4DS. 
Well, Yang's Guard command is pretty nifty, if for no other reason to increase defense. JCE's hack changed the spell used to Blink... now if that command hit rate info is found.. that would be even more interesting...
I'm slightly pissed at Cid.. that you gave him the Steal command (I have a slight updated finding about that) and you know how useless those Cure1 potions are? Give him the Medicine Command! (I know, it's lame, but for this part of the game, it actually isn't that counterintuitive!.
Anyway, there's a lot of things I'd change in that hack knowing what I do now. First off, "Cecil" would learn black magic instead of white, since I know how to change that now. The next character-mod hack I'd really like to do is one where Cecil starts as a naval officer of sorts and then becomes the Paladin. But Cain is the dark knight for the whole game, complete with uber dark-element weapons. I'm even toying with the idea of making Yang capable of using spears and having the Jump command...
Well, Cecil casting Black Magic isn't really "out of the box"... but eh, if you keep his stat growth like a Paladin (focusing on Will Power), Palom's Boast Command actually makes a ton of sense here.
I do really appreciate the descriptions of the weapons... You've certainly got more knowledge on how they work than I. I read your posts about equipping stuff in the thread about your GameFAQs post. That's really interesting insight into how to best equip your characters, some of it is counter intuitive. Thanks for the Item data updates on some of the bytes/bits too!
Most of it is my opinion, but if you go by how the FF series (at least the SNES one) calculates attacks against defense and evade, defense has less of an impact until it is closer to the max... evade has a stronger impact in general. Even though magic defense will generally look like it is in the vicinity of suckage, the spells enemies cast on you in generally aren't powerful to begin with. It is all relative to the enemies you fight against. Maybe it's just me that I prefer to trade defense for magic defense/evade (like FF6's choice between the Genji Armor vs Force Armor... I pick the Force Armor over Genji all the time).
Well...when I get some time to update that page I'll incorporate your data into there.
Ah, cool. Those are just my opinions.. feel free to use them if you wish.
There is going to be an "Objects/Items" section on FinalFantasyIV.net, eventually, when the stars align correctly or something, that will have detailed information on every weapon/equipment/item in the game. What's holding me back is the database design (not sure how best to implement it and the relational data tables right now) that and I'm going to use scans from one of the old NTT data books to add the original concept art of each object (some of them are pretty cool). However these images are going to probably take hours to scan and days to prepare for use. Anyway, I'll definitely be able to use your data there, along with the data in from the ROM.
Ah cool.. though I'm not sure why I'm not that into the fanart for this game...
