Hi thunderhill,
At the start of each fight, you can see the HP the monster has from the card that displays the stats.
The trick is to turn off Fast Scan otherwise you won't get all the addresses.
Once I do some damage to the monster that reduces its HP, I scan for a Decreased value.
There should be two values that is relevant to the monster. I then just modify it to 1 and then attack it again. If done correctly, its health bar will drop all the way to zero upon a successful attack (eg. the monster doesn't duck your attack).
Hope that helps.
hmm. will this work across every fight? From the looks of it, you have to do it for every new fight.
