Sounds like practically everyones having trouble with Valerie on rejuv - has something happened in a new update or sth? I remember destroying Valerie though... Maybe that's just me.
In V6 you're stuck on the boat and shore until you beat her. The water field makes all non water or flying types at half speed(unless you have swift swim), powers up her water attacks, increases chance of freeze and she's generally just difficult.
