Ribbits inhabit Elysea, Balaurea and likely also Asmodae.

But the Rock Shell Ribbits on the Mossy Forest Path are the most prized.

Why do you ask? Actually, the shell of a Rock Shell Ribbit isn't made of rock at all. It's made of fossils.

Player, would you collect fossilised shells at the Mossy Forest Path for me and bring them to the meeting point?
You want to trade fossilised shells this time?

Daeva looks embarrassed. Did Daeva not know that the relic searchers trade with the Changarnerk Traders?

Shugo will never tell a soul that Player is trading with relics, akakak.
