On this route, it is generally raining which weakens Template:Type2 moves while strengthening Template:Type2 moves. Once you climb up the stairs near the entrance, cross the bridge to find a honey tree. Then follow the path east and talk to the guy in the Black Belt clothes to receive TM66 (Payback). Once you follow the path north and defeat the Black Belt trainer, use Cut on the small tree to find another Black Belt trainer, along with the Fist Plate, which enhances Template:Type2 attacks.
