Belinsk Opera House

Located in Belinsk. Its main game purpose is after the activation of the Luna Tower and the Grave Eclipse Occurs. The summon Crystallux can be found here after defeating a Dark Devourer and two Dark Scuttlers. However after the party leave Belinsk, the Opera House cannot be entered again.

First Visit
Grab the Vial from a box to the left and a Smoke Bomb from a barrel to the right. The patrons inside will tell you that one of the chandelier’s here is actually a dragon.

Follow the path up to the second floor and back down to the back of the Opera House. In the back you can find 66 Coins from a barrel. The exit here leads back to Belinsk.

Second Visit
After the events at Eclipse Tower, saving both Eoleo and Hou Ju, Sveta's Spirit Sense will activate against her own will. After the scene, Kraden will then suggest going to the Opera House.

Inside take the right exit and follow the path. You'll see the monsters down below. Keep going and you'll get onto stage with them. Here you'll see the chandelier turn into a dragon, just like the legend. A small girl will come out and try to protect it, but get battered aside. The player will fight off the monsters.

This fight is against some normal monsters, and will take you but a minute to complete. After the fight you'll talk to the girl for a bit who will pass away, saddening the dragon. He'll want to help you in return, netting you the summon Crystallux which requires 3 Venus and 2 Mercury Djinn to use.
