::::::: Reduce Spell Damage ::::::
(Japanese Version Only)
Press down, right, left, up & then down again when the enemy starts to use
the magic attack. It will reduce the magic attack by 90% on Peter and 80% on
the others.
:::::: Increase Stats by 250 ::::::
(Japanese Version Only)
You must have 99 experience points, then get muddled by LV2 Muddle, because
LV 1 only decreases accuracy, and 2 makes you crazy. Then, the character must
attack one of your own guys, and HIT (not miss. I suggest that you "Quit" just
after being muddled, then try until it hits.) then you'll get a new level, and
stats will increase by 250!
:::::: Avoid all Attacks ::::::
(Japanese Version Only)
When your character is being attacked, press Right and C. The enemy will get
2 attacks and you will counter, but they will all miss.
