Lost Rex Cage (3)

Toul

Rucia's messenger arrived while you were gone, and asked me to find the key to the Rex cage. I'm sure that the Rex are suffering, cooped up in the cages for so long, so we need to let them out before it's too late. The Blackhands probably took the keys, but there's no way to tell which key will unlock the Rex cage you find. I guess the only thing you can do is take a bunch of keys from Blackhand Purgee Burglars around the Ruins of Lament and Cyclone Heights in Lux Plains. After you retrieve 20 keys, bring them to Rucia.

Rucia

Ah, you've brought the keys. I hope I can find the right key to the cage.
