Ah, it feels good to get back to making stat topics no one cares about.
HP: Duh.
SP: Actually not "duh"! The lower this is, the weaker your attacks get. I'm still working on figuring out an exact percent this takes it down, although it seems like 0% SP = 50% attack, 50% SP = 75% attack, 100% SP = 100% attack. Don't quote me on that though. SP goes down gradually (and I mean very gradually, over the course of a duel here a character might lose 2 or 3 points) while you walk/attack/etc. Walking in place to heal causes it to go down much faster, but no one is going to bother doing that in a duel anyway. These are pretty useless in a duel (unless you allow items), but I'll list 'em anyway for completeness.
AT(K): Ah, nothing can be simple with Izuna, can it? The visible attack of a character depends on what they're equiped with, HOWEVER each character seems to have their own hidden attack stat that grows as they level up. I'm not going to bother trying to make up numbers for the hidden stats, I'm just going to get each character's damage.
D(E)F: See AT, except substitute attack for defense.
Now a note on levels. Each character joins at level 1. They do not get experience if they are not in use, even if they are your partner in the dungeon. Yes, that is a terrible idea from a gameplay standard. This obviously creates some interp issues in regards to each character's level. I personally say take everyone at the same level. This isn't like in other games where they'll manage to gain levels as you advance through the plot and will just end up with a smaller level by the end of the game. Unless you take the time to go back and level grind each character to around the same level as your party, they're not going to be able to kill anything, and thus not going to be able to gain any levels. So that'd put everyone except Izuna at level 1.
Anyway, the only listed stats (HP and SP) have a certain level of randomness to them which I'll explain in a later post. Luckily, I found a FAQ that lists starting stats and average stats at levels 50 and 99. So I'll post a character's average stats at each of those benchmarks.
Each character can only equip certain weapons, and have varying skill with each. Eventually I'll try to post damage with each of these weapon types, but that is going to be a huge pain given varying weapon stats and the game mechanics, so bear with me. Some people may just disallow weapons since the stats are so random for them. For anyone interested, the weapon types are Claws, Swords, Arms, Ranged, Dolls, Boots, and Bows. Arms can be equipped with anything but Claws, Boots, and Bows.
