yea, thats the idea of pipeing... each time you enter the area the chance of a monster being its rare version changes
I would say that Frying Pan rules, only because of looks.
But Agito or Sange would be a good idea to try for.
I can't think like you about the Frying Pan Shadamoo
It's to weak.... but steals a lot of tp

Heh, get a Double Saber, it takes more TP. In the DC version you could get a Book of Katana (item part, akin to an enemy part). I have no idea wat its for.
