If you look at the FF VIII Character Elimination style, this is basically that but an FF IX version and a few additions and revisions. Every characters start with 180 HP, and on one post, you can heal, hurt and protect someone. Healing will add 30 HP, and attacking will take away 30 HP. Max HP is 300. If you protect a character, no damage will be done in the next turn. You can post after every 5 posts. Protect will only work after one post of another member.
These are all the characters. I hurt Queen Brahne (her hp is now 150), I heal Dagger, and I protect Eiko.

EDIT: OKAY, PROTECT WILL NEUTRALISE ANY ATTACKS. THIS MEANS NO ONE CAN DAMAGE IT IN THE NEXT POST. (In short, the character you protected will be invincible from the next poster.) Also, you can only post EVERY 6 posts. (I think this is enough) There you go.
