I've only just started on this with one game using my memory only before work, so not much has been added at all so far. I'd usually keep these things private to work on them further, but I thought I'd make this public in case of help anyone else can offer.

Uh, hm. That's pretty good, actually. Not totally complete, but a good start.
I've got to find a way to group these things together, the initial way I put the statuses was the easiest way I saw initially, but I imagine there's going to be much more to consider, and these groupings will change extensively before this is over.

some notes:
* There is no single skill that allows a person to afflict either allies or enemies with a "Saber" status. However, some enemies have access to both techs, which makes it as if they can target either.
status explanations:
* Werewolf - dramatically increases all stats. This status happens every night and goes away every day. This is no way to allict someone with it besides, uh, giving birth to them.
* Pressure point - makes the user as strong as their werewolf form, even in daylight. Has no effect at night. Essentially, this is a subset of Werewolf status -- it only matters during the day, can't be cured but goes away at the end of the battle.
* Magic barrier - gives the user new elemental advantages / weaknesses.
* Invisible - the afflicted is invincible for a short period of time.
* Snowman - the user cannot act for a short period of time.
* Chibikko - the user cannot do more than 1 point of damage or use Techs (more powerful attacks that require the user to hit the enemies X number of times before they can be used... something like AW2's CO power bar). Spells aren't affected. Enemies who become Chibikko'ed are turned into "Shell Hunters," which only give you 1 EXP when killed.
* Moogle - the user cannot use spells or do more than 1 point of damage per attack, nor can they use Techs.
* Moon Saber - normal attacks restore MP. The more damage done, the more MP regained.
* Leaf Saber - like Moon Saber, only for HP.
Undead creatures are reversed when it comes to Life/Death spells. A spell which restore life to normal characters has a chance of instantly destroying an undead one, while an instant death spell causes the monster to reappear a moment later, fully healed.
Also, there's a spell, Life3, which is supposed to be cast on a living character. When that character dies, Life3 kicks in, restores their life, then goes away.
The glitch is as simple as casting Life3 on an undead monster, then an instant death spell. The instant death spell causes the monster to vanish and then reappear, fully healed... but then Life3 is activated, destroying the undead monster. Fun!
