Have a Blitz/SwdTech cast on the user?

Haven't looked overly hard into how those cases work or are used to be honest, but for instance Possess normally uses the type of case I mentioned above to mark the ghost to be removed from the party after being used in battle.

If you knew how to make those cases run on demand you could have the player command, possibly monster commands... maybe, do whatever extra code you wanted to run. Think Capture uses the same thing to steal after the attack.

Add it to the default Fight command and you might be able to do a lucky 7777 strike like FF7. But as I said, I haven't done more than look at it so I'm mostly guessing in that peticular area as to what could be done.
