For anyone who's wondering...
The rockbeast fight is nothing but a complete waste of time. It took what felt like 10-15 minutes to kill him, and I almost died at that, with 1hp left at the end of the battle. Kinda retarded when you have to go Super Sonic (the problem's chronic!) and almost die to beat one lonely monster in a random encounter. You don't level up, you don't get anything for beating him as far as I can tell.
Anyway, it was...simply put, boring. I did kinda like the music though, being reminded of Grandia 2 felt good.
