ReCast FF3: War of the Magitek

Glad you're enjoying it. Riverstep (the slot 4 dance) should be learnable in any blue cave (such as the cave to South Figaro), as well as on the Veldt and in the Magitek Research Facility. There might be a few other places for it, but Zozo teaches CliffJive because the skyscrapers are like man-made cliffs.

You're probably thinking "Why the Veldt?". Because Barren Falls dumps out on the Veldt, so a water dance felt appropriate to learn there.

You won't learn the slot 8 dance until the World of Ruin.
