Doom - Like said earlier, places time limit on enemies life.

Card - Also talked about earlier, changes enemy into a card. You get NO exp after battle.

Mad Rush - Casts Haste, berserk, Protect, and shell on all characters.

Treatment - Cures negative status effects. Same as esuna or remedy but no cost of items or spells.

Defend - reduces damage from P.Attacks.

Darkside - This is in other games and called other names like darkness. You sacrifice some HP to damage a foe.

Recover - one of my most favorite commands, this restores all HP to a single target. This command is an instant death attack to undead/zombie foes. Its way better then using your cure spells which can be kept for stat increasings.

Absorb - Like drain but with this command you dont waste magic or items.

Revive - I like this as much as recover. It cures a KO'ed member with 100% of their life back. Much like a Full life spell but without the cost.

Mug - Can steal items from monsters. Sometimes the items you steal are different then what can be droped. Rare-Item ability can change the items droped and stolen.

Kamikaze - Sacrifice a character to damage foe. Not worth it in my opinion, the character dies and the damage isn't that great.

Level Up - Allows you to level up by 10 or so levels. Cap is still level 100 and the effect only lasts during the battle. If you use it on your enemies they will be stronger but they will also give you more EXP after battle.

Level down - Use to lower levels of targets. good for when you are fighting something tougher then you. it evens up the score nicely. Same as level up but reversed. Effect only lasts during battle. Sadly, it would have made for a good stat max cheat if effect carried on.

Devour - A command that lets you eat your opponent. The effects range from boosting stats, restoring HP or plain out harming you.

Well thats all the commands. I usally like to keep my characters like this

Recover
GF

Sometimes I change treatment in for mad rush if I know I can defeat the enemies with no problem.
