Cliff's transformation quest..

One question; is it repeatable?

I don't believe so. But you can trade 10 Rascal snowpieces for this party transform potion that affects everyone in your party [not sure about yourself]

it is repeatable, actually, it's marked "daybyday" like the Naomi quest was the first time it came out, so we should be able to find out in about 1 hour 15 minutes :p
